History of Environmental Health



Environmental Health Practice in Nigeria

History of Environmental Health 

PREPARED BY ENVIRONMENTAL HEALTH OFFICERS REGISTRATION COUNCIL OF NIGERIA (EHORECON)    www.ehorecon.gov.ng/welcome 

The history of and the development of Environmental Health are unique and complex in every country of the world. It is not possible to assign a specific date from which problems relating to environment started. However, the need to control the environment in the interest of public health has been evolving for a long time. For convenience, it has been possible to divide the evolution of environmental health control into four time zone in which time can be assigned. First, the agricultural revolution following Malthus observation (1750-1850). The period was characterized by low living standard among the farmers who lived in overcrowded damped houses, bearing large number of children, and eating poor diet. There was also marked increase in the number and incidences of diseases and deaths, poor domestic environment and low life expectancy. Second is the industrial revolution of 1850-1900, which witnessed the beginning of industrial pollution as a result of using rudimentary machines and unprocessed toxic substances for industrial processes. The third is the period between 1900 and 1945, while the fourth is 1945 to the present date.
The initial phases of sanitary activities centered on keeping human excreta out of food. Indeed, about 10,000 BC, nomadic hunters simply left their wastes and move to another location. Today, the field covers an imposing spectrum of activities of high technical and scientific dimension. The trend has been to draw away from activities, which involve repair, correction and enforcement toward programmes that are proactive and promotive in nature. Until recently, public health activities have been based upon negative concept, resulting in programmes designed to attack things that have gone wrong like isolating infected person, filling decayed tooth or purifying polluted water. Now, environmental health principles are focused on maintenance of cleanliness, promoting hygiene practices and prevention of ill health.
Environmental health programme (EHP) being perfected today started during the industrial revolution of the 18th and 19th centuries’ following the mass migration of people from rural areas to the cities in search of jobs. Living conditions then became poor and outbreak of several communicable diseases with high morbidity and mortality became rampant. In 1842, Edwin Chadwick of Great Britain, a Lawyer by profession spearheaded the Poor Law Commission, which enquired into the sanitary condition of the labouring classes. The report of the Commission recognized the association between the general environment of the dreadful living conditions of the poor and the development of illness. This led to the enactment of the 1848 Public Health Act, which was borne out of the desire to control these environmental conditions and abate them. !!!!!!!!!!!!!!
In Nigeria, the development of environmental health has had a more challenging history. As far back as the 18 th century the Colonial government took the issue of À preventive health services serious because of the need to prevent the breeding of mosquitoes, which was a major killer of the colonial settlers. They introduced the then Sanitary Inspectors to the Colony of Lagos. The position of the Sanitary Officer was a very top position in the then Colonial government. That was why the Senior Municipal Sanitary Officer was statutorily made a member of the Legislative Council in 1913 on the amalgamation of both the Southern and Northern Protectorates of Nigeria, (Akinyede, 1957).
The present day environmental health services in Nigeria started in 1920s, when Dr. Isaac Ladipo Oluwole came back from Britain as a Public Health Physician. He was the first African Medical Officer of Health (MOH) in the Lagos Colony, who also pioneered the establishment of School Health Services using the then Sanitary Attendants. His focus then was on inspection of schools and vaccination of school children in their school. He also started the first Nigerian School of Hygiene at Yaba, Lagos in 1920 (now School of Health Technology), where qualified persons from all over Nigeria were trained as Sanitary Inspectors. At the end of their training, they obtained the Diploma of the Royal Institute of Health (R.I.H) London, which was later changed to Royal Society of Health (R.S.H) Diploma, London. The work of Sanitary Inspectors was greatly noticed during the outbreak of bubonic plagues in 1924, when Dr. Oluwole revitalized Port Health Services and sanitary inspection of ships and port premises. Their impact was much felt during the control of yaws of 1930 and small pox of 1970s. Since then the development of environmental health in Nigeria has continued to increase in terms of the number of practitioners trained and number of schools training the practitioners.
To a greater extent, the development of environmental health in Nigeria has been retarded due to the dominant influence of the medical profession, which assumed superiority and erroneously annexed every thing health into medical practice. Again unlike in other countries where people other than physicians initiated some environmental health control; in Nigeria, environmental health services were initiated by a physician. This strange marriage existed for so long that it was nearly impossible to establish or convince any one that environmental health was a profession. Whereas WHO has recognized environmental health as a profession, it was totally impossible to say so among policy makers in the health sector in Nigeria.
The development of environmental health profession started in Britain in 1877, when the Royal Sanitary Institute was established. Even in Britain, environmental health was not recognized as a profession till late 1956. In Nigeria environmental health has existed as an occupation since the days of colonial administration when the practitioners were known as Inspector of Nuisance. Despite their contribution to environmental health control in the 1920s to early 1980s, there was nothing to suggest that this group of health workers merited professional recognition.

Environmental Health Officers Registration Council of Nigeria

Environmental health remained unregulated in Nigeria over the years until 2002, when the democratic government then decided to grant it professional recognition through the enactment of the Environmental Health Officers (Registration, etc) Act 11 of 2002. The Act established the Council charged with the responsibility of regulating Environmental Health profession in Nigeria. The specific objectives of the Council include:
  • determining what standards of knowledge and skill are to be attained by persons seeking to become members of the profession of Environmental Health and improving those standards from time to time as circumstances may permit;
  • securing in accordance with the provisions of the Act the establishment and maintenance of a register of persons registered under the Act as members of the profession and the publication from time to time of lists of those persons ;
  • conducting examinations in the profession and awarding certificates or diplomas to successful candidates as appropriate and for such purpose, the Council shall prescribe fees to be paid in respect thereof, and
  • performing the other functions conferred on the council by the act.
 
The first Council of eleven members was inaugurated in March 2004 by Col. Bala Mande (rtd), the then Hon. Minister of Environment, on behalf of the President of the Federal Republic of Nigeria. Since then, the members have dedicated themselves to the cause with great determination, in the face of daunting challenges to carry out the mandate of the Council. To this end, the Council opened register in July 2004, in which members have been registering. It has developed various curricula for the training of its members and has also been conducting examinations for new entrants into the profession. The Council is reaching out to other professional bodies and stakeholders for the proper regulation of the field and is determined to continue to explore every avenue to ensure that Nigerians live in an environment devoid of hazards and threats to their lives, which also increase disease burden, which is currently more than 70% environment related in the country.

Environmental Health Practice

Environmental health has been defined recently as comprising of those aspects of human health, including quality of life, which is determined by physical, biological, chemical, social and psychological factors in the environment. It also refers to the theory and practice of assessing, correcting, controlling, and preventing these factors that can potentially affect, adversely the health of present and future generations. Environmental health programmes are organized community efforts to monitor and modify man environment relationships in the interest of better health.
Environmental Health is a major branch of public health, which plays a significant role in disease prevention, control and the sustenance of environmental integrity. It has been defined as ‘the control of all factors in man’s physical environment which exercise, or may exercise, a deleterious effect on his physical development, health or survival’. Environmental Health therefore is a broad concept in public health, which is ‘the science and art of preventing disease, prolonging life and promoting health through organized efforts of the society.
The outcome of environmental health organization is the prevention, detection and control of environmental hazards which affect human health through the following functions as specified by World Health Organization:-
  • waste management;
  • food control and hygiene;
  • pest and vector control;
  • environmental health control of housing and sanitation;
  • epidemiological investigation and control;
  • air quality management;
  • occupational health and safety;
  • water resources management and sanitation;
  • noise control;
  • protection of recreational environment;
  • radiation control and health;
  • control of frontiers, air and sea ports and border crossing;
  • pollution control and abatement;
  • educational activities (health promotion and education);
  • promotion and enforcement of environmental health quality standards;
  • collaborative efforts to study the effects of environmental hazards (research);
  • environmental health impact assessment.(EHIA).
Environmental Health Practitioners
Environmental Health Officer (EHO) is one of the health professionals whose creation was based on need and exigencies rather than desire or sentiments. This was the case since 1831 in Britain when the first set of Sanitarians were put together to control the worst cholera outbreak in that country. The 1848 Public Health Act provided for the appointment of Inspector of Nuisance to tackle sanitary issues.
The Inspector of Nuisances as of then had no qualification, and their main job was to point out all breaches of sanitary regulations and enforce the byelaws and rules of the council and health committee. It is worthy of note that in the 1846 Liverpool Sanitary Act, the Inspector of Nuisance was defined as an officer of the council independent of the Medical Officer of Health, but by nature of his functions, cooperates closely with him. It should also be noted that as far back as 1860, Edmund Parkes, the first Professor of Hygiene developed Military Hygiene into a science before the Army Medical School became the Royal Sanitary Institute, and Inspectors of Nuisance have had their recognition not just as health professional but as key operators in the prevention of diseases.
In 1877, the Royal Sanitary Institute was introduced with specific training for Nuisance Inspectors. With the acquired skills and knowledge, their role changed with the change in title in 1956 to Public Health Officer, and again in 1974 to Environmental Health Officers. These changes mirrored increasing expertise, as inspector acquire more knowledge about pollution and other environmental hazards.
In Nigeria, the pattern and change in nomenclature followed that of Britain; from Sanitary Attendants in the 1915s to Sanitary Inspectors of 1930s, to Health Superintendents of 1970s, and to (EHOs) in 1988, which brought the nomenclature in line with the international recognized and accepted name for the practitioners. The EHOs came into existence in Nigeria as a distinct occupational group during the colonial era and they were known as Sanitary Inspectors. Their duties included sanitary inspection of premises, control of infectious disease such as yaws, small pox and other such diseases; disinfections and disinfestations, liaison with other professional groups on disease control efforts, prosecution of sanitary offender, verification of notices issued and enforcement of environmental health standards, laws and regulations.
Sanitary Inspectors were a force to reckon with in the colonial era in the area of preventive health services in Nigeria. This cadre of professionals forms the backbone of environmental health services worldwide. Their training is related to the environmental health aspect of a cross-section of development sectors, with emphasis on inter-sectoral liaison, community participation and health promotion.
EHOs today may be regarded as the general practitioners of public health since they are in daily contact with the source of ill health in the community, but their training, qualification and job evaluation put them at par with any other professional group with specific responsibility on environmental health control. This is enormous responsibility, which is capable of lifting the profession and the practitioners to the sky, can equally bring them to the mud. EHOs therefore must take the challenge and responsibility for failures in the health status of our communities as their role in disease prevention, health promotion and rehabilitation is a direct consequence (positive or negative) of how we fare. It is the failure of environmental health control programmes that determine what happen in the other spectrum of the health care delivery system, more so as over 70% of health problems on Nigeria are environment related.
EHOs are well placed to participate meaningfully in new approaches to environment and health management. Presently, there exist a scientific society, the Society for Environmental Health of Nigeria and an Environmental Health Officer’s Association of Nigeria, a professional group whose aim is to protect and promote the welfare of the professionals. The profession also has sub-professional groups that must work under the supervision of the EHOs. These cadres include:
  • Environmental Health Technicians
  • Environmental Health Assistants.
The challenges posed to mankind by inadequate management of environmental factors, emerging and re-emerging of infectious diseases in our communities, have necessitated the need to regulate the profession and strengthen the professionals.
To perform environmental health functions effectively, the EHO requires: (i) investigative skill; (ii) analytical skill; (iii) communicative skill; (iv) educative skill; (v) organizational skill and (vi) attitudinal skill.
EHO activities include:-
  • Administration, inspection, education and regulation in respect of EH. EHO is a generalist across the range of basic EH activities.
  • Surveillance over health related environmental conditions, including necessary monitoring activities, providing professional advice and guidance, thereby gaining community confidence and encouraging participation.
  • Acts as a public arbiter of EH standard, maintain close contact with community. Must at all time be aware of the general environmental circumstances including new hazards to health in his area of jurisdiction and what resources are available to tackle them.
  • Application of professional standard in his work in relation to non-professionals involved in EH, and relate professionally with other health professionals like physician, veterinarian, toxicologist, sanitary engineer, laboratory scientist, nurse etc.
  • Maintenance of effective liaison with other professional officers who have a contribution in promoting EH eg water resource manager; waste manager; housing manager; rodent, pest, insect control officers; and recreational facility manager. EH is much a team concept, and this must be recognized in any organizational arrangement.
  • Carry out the well-established duties of sanitarian, including inspection of housing and food hygiene, monitoring and control of new hazards due to intensive industrialization eg pollution by chemical, biological and physical agents; and preventive role in relation to environmental hazard to health.
  • Understanding the principles and practical knowledge involved in personal health, animal health, microbiology, provision of water etc. This will enable him contribute to broad base decisions and to make the decisions alone. He must understand the environmental aspects of the problems, which are the concern of other professionals, and contribute to their solution.
  • Plan and coordinate activities between different professional discipline, agencies, authorities, and maintain continuous link with these professionals eg physician, microbiologist, chemist, civil engineers, veterinarian, lawyers, technician and other ancillary personnel and artisans.
  • Act independently in both advisory and enforcement capacities, exercising self-reliance and initiatives, functioning as a member of broader team with other professionals in implementing environmental health programme.
  • Interpret legislation, promote and maintain standard and solve problems, which may come to light.
  • Acquaint self with actual or potential environmental hazards and ensure that appropriate action is taken to deal with them – with the backing of strong legislation.
  • Combine training in public health, toxicology and environmental sciences to enable him cope with such problems as soil pollution, chemical pollution, liquid radioactive wastes from industries, pollution of the home environment due to such products as cosmetics, detergents, paints, pesticides and gas fuel; heavy metal contaminant eg mercury, barium, cobalt and other metals, and new problems in food safety such as irradiation of food.
  • EHO within the public service should perform the following basic functions:-
- improve and protect human health from environmental hazards,
- enforce environmental health legislation,
- develop liaison between the inhabitants and local authority, and between local authority and higher authority,
- act independently to provide advice on environmental health matters,
- initiate and implement advocacy and health promotion and education programmes to promote an understanding of environmental health principles.

World Environmental Health Day, 2014 Commrntary

IN CELEBRATION OF WORLD ENVIRONMENTAL HEALTH DAY 2014 WITH THE THEME: ADDRESSING ENVIRONMENTAL HEALTH INEQUALITIES” WRITTEN BY Sanitarian ISAH ADAMU, MEMBER, REPRESENTING NIGERIA ON THE COUNCIL OF THE INTERNATIONAL FEDERATION OF ENVIRONMENTAL HEALTH (IFEH)

The World Environmental Health Day (WEHD) was declared for commemoration in 2011 by the International Federation of Environmental Health (IFEH) to bring world attention to the vital role of environmental health profession and services to the improvement of health and well-being of the earth’s inhabitants. The Council of the International Federation of Environmental Health Proclamation of 26th September 2011 as the foundational World Environmental Health Day which would be commemorated every September by diverse interests with stakes in Environmental Health the world over. In that famous declaration, the IFEH Council considered various fronts from which the noble profession of Environmental Health positively impacts, central to which is the continuing threats to human health posed by pollution, climate change, urbanisation, globalisation  and poverty, among others and the urgent need to adopt a preventive approach so as to maintain and improve the quality of the natural environment, air, water, food, housing and communities in order to reduce the impact of disease and the public health.
There is no gain-saying to stress the need identified by the Federation in addressing the hydra-headed problems associated with climate change, urbanisation and excruciating poverty to which the developing world is seriously exposed especially the sub-Saharan Africa where our dear country is located. The urbanisation occasioned by the Industrial boom of the early 19th century in Europe set the stage for the complex interaction between Man, his environment and Etiologic Agents of diseases. In the process, diseases hitherto unknown emerged including Plague and Cholera and devastated a sizeable population. In Great Britain, the Cholera outbreak in Northern London was traced to contamination of sources of drinking water with human excrements. The Poor Law Commission which investigated the matter, resulted in the enactment of the Public Health Act in 1848 which introduced a brand new public servant – the Nuisance Inspector responsible for monitoring human endeavours for the purpose of tracking infractions in daily life that could harm human health. This further gave rise to the metamorphosis of the Nuisance Inspector to that of Public Health Officer in 1950s, and finally the Environmental Health Officer in 1972 – spanning over a century. It is important to note that it did not end with just the change of nomenclature but rather encompassed the birth of a profession amidst the array of professions flourishing in Britain and elsewhere in Europe namely the Environmental Health Profession. This resonated to Nigeria where the Sanitary Attendants changed to the Sanitary Inspectors who worked in the then British colonies making the Senior Municipal Sanitary Officer a statutory member of the Legislative Council in 1913 on the amalgamation of both the Southern and Northern Protectorates of Nigeria. Like in Britain the transformation continued until the mid 1980s culminating in the designation, Environmental Health Officer (EHO).
This leads us to ask what Environmental Health means. Simply put, Environmental Health refers to the control of all factors in man’s physical environment which exercise, or may exercise, a deleterious effect on his physical development, health or survival. This for sure is one of the integral parts of Public Health which aims at promoting health and prolonging life of the human being. In Nigeria this noble profession is composed of these components: waste management; food control and hygiene; pest and vector control; environmental health control of housing and sanitation; epidemiological investigation and control; air quality management; occupational health and safety; water resources management and sanitation; noise control; protection of recreational environment; radiation control and health; control of frontiers, air and sea ports and border crossing; pollution control and abatement; educational activities (health promotion and education); promotion and enforcement of environmental health quality standards; collaborative efforts to study the effects of environmental hazards (research); and environmental health impact assessment.(EHIA).
The Federation, in supporting the World Health Organization’s declaration through the World Health Assembly resolution (WHA65.8) which welcomed WHO’s move to facilitate equitable access to health by all through “all-for-equity” and “health-for-all” global actions, therefore decided to focus attention in this respect hence this year’s WEHD theme “ADDRESSING ENVIRONMENTAL HEALTH INEQUALITIES” becomes very relevant most especially in Nigeria where the health sector is prepondently turned to medical circle with the Nation paying dearly for this. The WHO declaration significantly focuses most attention to the Social Determinants of Health as emphasized by the Commission which did the study and prepared its report from which the resolution was arrived at, that health equity was not only achievable but was the right thing to do. These determinants include among several others, Economic ventures; Housing; Transportation; Education; and Infrastructure provisioning. It is evident that each one of these portends a great deal of danger to the health of Nigerians in no small measure since all of them individually or collectively place an individual, a family or indeed a Society on a position in the social gradient. Inadvertently peoples’ standing on the gradient determines how healthy or otherwise they will be such that the poorer the person the lower the position they occupy. That is why Nigeria’s standing on the WHO Country profiles is nothing but discouraging as the gap between the poor and the rich, the educated and non-educated; the urban-based and the rural-based is so wide. These combine to paint a rather gloomy picture of Nigeria’s morbidity and mortality indices.
In considering the health inequalities, IFEH has decided to work with partners ‘to close the gap in inequities within a generation’ by means of improving Environmental Health Services world-wide.
As has been established inequity and inequality lead to poor health. In fairness, the worst kind of inequity is that in regard to health services where in Nigeria like in other settings, have been ‘medicalized’. This is evident in the allocation of resources; prioritization of policies and programmes at every tier of Government whose leadership are mostly concerned with provision of hospital buildings, equipment and consumables as well as hospital-based manpower, leaving out the preventive health aspect. For any addressing of health inequalities to succeed, Governments and societies must have a re-think concerning environmental health which is the vehicle that will improve the Social determinants of health that will in turn impact on the goals of WHO’s resolution 65.8. Over the years Environmental Health has been relegated to the background as a result of neglect of the highest order, little wonder that the country’s morbidity and mortality continue to deteriorate because the basics have been forgotten. The Federal Government that ought to provide leadership is not willing, the State governments that are supposed to guide feel unperturbed while the Local Government which has responsibility to deliver EHS is grounded and moribund.  
In addressing health inequities, the starting point should be addressing environmental health inequalities by accepting the roles assigned to the profession of environmental health by the WHO. When one takes a look at the housing sector for instance, what is glaring is the existence of slums not only in the densely populated settlements but also in high profile or exotic settlements where inhabitants feel they are above board. In fact you technically can detect a lot of issues that warrant declaring some high brow dwellings as posing health risks for their inhabitants. The collapse of building is a common occurrence now – this is mostly attributed to failure of engineering. Agreed, but collapse does not happen overnight, it gives signs like cracks on the walls especially near beams or pillars which degenerate to the point of having the strength of the building compromised. This could easily have been detected by the simple routine Sanitary Inspection of Premises can reveal the smallest potential threats which would be highlighted in the improvement notice to the owner report of which would be forwarded to the town engineering department to enable appropriate actions. Other health hazards include poor ventilation leading to poor air circulation consequence of which is impacting negatively on both out-door and in-door air quality,   as the buildings are erected without recourse to health considerations. Poor ventilation gives rise to moisture which attracts disease vectors like mice and cockroaches and mold which cause and/or aggravate allergic illnesses. In the same manner, finishing materials like paints are improperly used leading to chronic lead poisoning. Due to unavailability of adequate human and material resources, these go unchecked to the extent that buildings remain uninspected for a long period of time and hence resulting in the exacerbation of housing associated health hazards which are silent causes to disease conditions.
The same scenario plays out in the other components of Environmental Health thereby resulting in very poor health indices as reflected by Nigeria’s high morbidity and mortality which are mostly attributable to poor environmental health services organization and management. The conscious and combined efforts of those who think are lords and who know it all in the running of the health services has ensured that environmental health services (EHS) remain the way they were when bequeathed by the colonial masters in the mid 20th century. This way, their myopia has ensured that environmental health is thus reduced to only everyday sanitation and hygiene when it goes far beyond that. If it were only for sanitation and hygiene, the G-7 nations would not have any needs for it, but quite contrary the world economic super powers like Great Britain and the United States of America do not only maintain robust environmental health structures but also prioritize it among their most important services at all levels of governance.
It is imperative to note that poor leadership of EHS has been the major drawback. At the Federal level, the absence of a full pledged Directorate of EHS in any Federal Ministry has left the profession vulnerable without the much needed leadership thereby leaving it in the wilderness and scattered around the Ministries of Environment and that of Health – resulting in conflict of authority between the two. Despite all entreaties spanning decades the Government is yet to be allowed to do the right thing as every move is blocked by the ‘chosen ones’. This is a form of inequality that remains fatal till today. A sharp comparison is what obtains in our peer that is South Africa which has a Directorate of Environmental Health headed by an EHO in the National Department of Health which is the equivalent of our own Federal Ministry of Health.
It is quite reprehensive that despite having avalanche of well trained Environmental Health Officers who distinguished themselves in their chosen career in the Federal Civil Service, it was not until 2008 that an EHO was promoted into the Directorate Cadre much to the amazement of many. As is known, the Directorate cadre is the circle where policy statements and decisions are moulded for upward submission for approval. This is the policy level where critical thinking, professional articulation and masterly deliveries are supposed to lead via sound professionals well grounded in the job are at the helms of affairs. In place of the rightful bearers of these positions – the EHOs, the job of articulating professional inputs for EHS is left at the mercies of clinicians who by virtue of their training are not equipped to lead EHS. The end result is so glaring for everyone to see. What is more manifest as inequality than this?
The budget of EHS is virtually nonexistent at levels. Where some budget line is provided is solely for municipal solid waste disposal. This is an ugly trend where an important and very crucial sector is maligned and marginalised in terms of funding whereas other health services which are basically clinical get the lion share year-in year-out without justifying the huge sums allocated evident in the ever rising cases of environmental sanitation-related diseases in the country. For the country to make meaningful progress in disease control, preventive health – in all its ramifications must be accorded the necessary attention it desires most especially funding which is the bedrock of any service provisioning.
As Environmental Health flourished in the 1970s the Federal Government in collaboration with the World Health Organisation concluded that it was time that its status needed academic upgrading to suit the changing socio-economic realities in the country. This resulted in the introduction of the Bachelor Degree in Environmental Health programme at the then University of Ife in the early 1980s. To the surprise of Environmental Health family, the Programme was rationalised just after graduating two sets of trainees. The rationalisation, it was much later discovered was achieved as a result of the plot of the self-acclaimed leaders of Nigeria’s health team who touted that there was no need for the then Health Superintendent and Medical laboratory cadre to acquire first degree. For over three decades now Environmental Health Officers’ quest to reach the zenith in the Civil service remains a mere desire as the best they could attain is reaching the bar and retiring at the salary grade level fourteen i.e the Chief Environmental Health Officer cadre.  It is however heart-warming that this situation is gradually becoming history because a few Nigerian Universities with support of the National Universities Commission have reintroduced the programme which the EH community regard as a turning point for the profession such that the educational inequality is eliminated once and for all. In another respect, the profession was most unpardonably sidelined in partaking in the highly regarded Master of Public Health (MPH) programme which was exclusively reserved for physicians when it commenced in some of the first generation Federal Universities in the 1980s. A drama played out when one of us was admitted into the programme in one of the Universities but was refused registration for not qualifying to have been admitted in the first place since he was not a medical doctor. The fellow refused to give up and passionately struggled and succeeded to be registered. It was most ironical that the same unqualified fellow emerged the best student among his ‘super qualified’ physician peers.  We are however glad that this is changing and members of the profession are proving their worth among the diverse professionals who make it into the MPH programmes of non conservative Nigerian Universities.      
Another element of inequality was meted out on EH in the 1990s when the Federal Government granted professional status to every cadre in the health industry by establishing regulatory bodies for them through Military Decrees except the Environmental Health cadre. In explaining it away, the then Minister of Health, a well decorated and celebrated Physician who initiated and ensured the success of the monumental change, upheld that Environmental Health needed not to be recognised as a profession but rather a mere occupation. The fear was if EH was empowered, it would not continue to be the milking cow of the medics. This, the EH family have understood through the fact that, take away Environmental Health Officer, any other health professional is clinic based. And that when his job is robustly done, all other clinic based cadres will have little to do since diseases are prevented thus leading to reduction of clients’ traffic into hospitals for medication.
Fortunately albeit lately, the more-than-fourty-year-struggle for the cadre’s recognition as a profession came to fruition in 2002 when the then President of the Federal Republic of Nigeria, Chief Olusegun Obasanjo assented to the Environmental Health Officers Registration etc Bill into Law giving birth to the Environmental Health Officers Registration Council of Nigeria. There has since then, been tremendous improvement in the services rendered by EHOs nationwide while all necessary policy frameworks are being put in place to ensure that EH regains its pride. Governments at all levels are indicating readiness to returning to the good old days when Environmental Health was the fulcrum of healthcare services.
The IFEH calls on National Governments including that of Nigeria, to make their policies and programmes embrace all the key sectors of society not just the traditional health sector that limits itself to the medical model of public health. It also emphasizes as the WHO Commission has argued, “that in any country the ‘Minister of Health’, who should also be the lead on environmental health issues, and the supporting officials, are critical to achieving the necessary changes. They can champion a ‘social determinants of health’ approach at the highest level of society, they can demonstrate effectiveness through good practice, and they can support other ministries such as the economic, social, housing and environment, as well as planning authorities, in creating policies that promote health equity”.  Furthermore the Commission asserts that “‘achieving health equity within a generation is achievable, it is the right thing to do, and now is the right time to do it”. The Nigerian Government is therefore strongly advised to embrace this clarion call of the WHO in order to make the much needed progress of reducing morbidity and mortality – by improving Environmental Health Services. Little wonder therefore that the slogan of the profession in Nigeria, Sanita Sanitatis; Omni Sanitas – in latin meaning, ‘The health of one man is the health of all’ continues to be relevant any day.
