Varies by country, usually requires a degree and/or certification
An environmental health officer (EHO), also referred to as an environmental health practitioner (EHP) or public health inspector, is a person responsible for carrying out measures to protect public health,[1] which includes the administration and enforcement of legislation related to environmental health and safety hazards.
EHOs aim to keep water, food, air, land, facilities, and other environmental attributes in compliance with local legislation. They control health hazards, including biological, chemical, or physical through the application of environmental safety law. EHOs address factors influencing human behavior outside the workplace. In contrast, workplace factors, such as workplace injury, are addressed by Occupational Safety and Health officers.[2][3] They also assess and control environmental factors that can potentially affect health to prevent disease and create health-supportive environments.
Environmental determinants of health, such as air, water, and food quality, are significant factors in a community's overall health and well-being. Inspectors play a crucial role in improving population health by reducing the incidence of disease and its consequences.
EHOs are trained to maintain a safe and healthy environment for the public.[4] They often require a degree[5] and additional training and certifications, including public health inspections, policy development, emergency response, disease prevention and control, and health promotion and education.[6][7] EHOs are responsible for preventing and addressing health risks as well as educating the community about these risks.
EHOs may be familiar with microbiology, epidemiology, chemistry, toxicology, environmental science, and food science. They are skilled in tracking and controlling communicable diseases and investigating environmental health incidents.[8][9] They must also be familiar with relevant laws and regulations related to public health and safety in their region. As practitioners, they work with government agencies, local municipalities, businesses, and community groups to protect public health. Depending on the specific laws and definitions in their jurisdiction, environmental health practitioners may also go by other titles, including environmental health specialist, public health inspector, and health official. Some historical titles for this role include inspector of nuisances, sanitarian, and sanitary inspector.
Local, state, or federal health departments usually employ environmental health professionals to advise and enforce public health standards. However, many are employed in the private sector, the military, and other third-sector agencies such as charities and nongovernmental organizations.
Roles and Responsibilities
Environmental Health Officers are involved in:
Inspection and enforcement services
Environmental health consulting and education
Communicable disease investigations and outbreak control

EHOs are employed by local, state, or federal health departments, private sectors, military, and third-sector agencies like charities and NGOs.
Local Authorities: Enforcing health regulations at local councils.
Government Agencies: Working in agencies like CDC's NCEH or EPA.
Public Health Organizations: Ensuring compliance with health and safety standards.
Private Consulting Firms: Specializing in environmental health and safety services.
Private Sector and Healthcare: Roles in public health, healthcare, occupational safety, and more.
Occupational Health and Safety: Ensuring worker safety in both public and private sectors.
Environmental Protection and Sustainability: Addressing issues related to climate change and sustainability.[12][13][14]
An EHO investigates health hazards in many settings and will take action to mitigate or eliminate hazards.[15] Depending on the jurisdiction, EHOs may have broad job duties, including inspecting swimming pools, substandard housing conditions, shelters, public schools, daycares, nursing homes, conveyances (e.g., cruise ships, ferries, airplanes, trains), and personal service establishments (e.g., tattoo parlors, tanning salons, beauty salons, laser hair removal facilities, barbershops).
EHOs may also permit and inspect wells, private water systems, and individual subsurface sewage disposal (septic) systems. Other tasks include campground inspections, special events inspections, waste management inspections, petting zoo inspections, correctional facility inspections, mobile home park inspections, and homeless encampment inspections.
Some EHOs are trained in communicable disease control and prevention. During a disease outbreak they may investigate and recommend/apply interventions to stop the spread of disease. They may also be trained in noncommunicable disease (NCD) prevention and control. They can work to prevent NCDs and control risk factors. EHOs also may play a vital role in community projects such as those concerning health promotion, health equity, tobacco use reduction, healthy built environments/healthy communities, food security, and emergency preparedness.
They may also respond to complaints such as animal bites (rabies control), garbage complaints, noise complaints, odour complaints, or sewage overflows. Depending on their educational background and training, they can provide information and referrals concerning lead, radon, mould, and emerging diseases (e.g., West Nile virus, avian influenza, COVID-19). The field also overlaps with hazardous materials (hazmat), and many hazmat responders are licensed environmental health practitioners or registered environmental health specialists.
During a public health emergency, such as a pandemic, they may take on crucial emergency response roles, provide public education and advice, enforce public health orders, and take necessary actions to protect public health. Likewise, they respond to other emergencies such as natural disasters by undertaking roles outlined in emergency response plans.
Related Roles
Related roles include environmental health scientists, policymakers, safety inspectors, and others.
The common identifier of environmental health personnel is that they are responsible for the identification, evaluation, and management of risks to human health from factors in the environment, whether on behalf of government agencies or private sector organizations.[14]
Working conditions
Environmental Health Officers (EHOs), also known as Public Health Inspectors, have working conditions characterized by a variety of factors:
Work Environment: EHOs typically operate in diverse settings, including government agencies, private companies, and non-profit organizations. Their role often entails visiting various locations, such as restaurants, public facilities, and industrial sites, to ensure adherence to health and safety regulations.
Schedule: The work schedule of EHOs can be variable. While some may adhere to regular business hours, others might work evenings, weekends, or be on-call for responding to public health emergencies.
Physical Demands: The job can be physically demanding, requiring EHOs to spend long periods on their feet and sometimes work under challenging conditions. Handling and testing samples is also part of their duties, necessitating manual dexterity and strict adherence to safety protocols.
Mental and Emotional Demands: EHOs face the challenge of keeping up-to-date with complex regulatory frameworks and public health guidelines. Dealing with non-compliant operators or handling public health emergencies can add to the stress levels.
Travel: Frequent travel within their jurisdiction is common for EHOs, and they may occasionally need to travel farther for training or conferences.
Safety Risks: EHOs are sometimes exposed to health and safety hazards, including hazardous materials, contaminated environments, or infectious diseases. This necessitates the use of protective equipment and strict safety procedures.
Training and Continuous Learning: A degree in environmental health or a related field is typically required, along with ongoing professional development to stay current with regulations and best practices.
Interpersonal Interactions: The role involves significant interaction with the public, business operators, and other stakeholders, necessitating strong communication and sometimes negotiation skills.
Job Satisfaction: Many EHOs find their role satisfying, as it significantly contributes to public health and safety.
Career Advancement: Advancement opportunities may include specialized roles, supervisory positions, or movement into related fields like policy development or environmental consulting.[16][17]
History
The role of environmental health officers (EHOs) has evolved significantly over the centuries, beginning as early as the Renaissance in the Republic of Venice, where a type of court of health inspectors was established to contain the spread of epidemics. These inspectors, appointed by the Venetian Senate and later by the Council of Ten, were among the earliest forms of organized public health efforts.
During the early Industrial Revolution, particularly under the Factory Act 1802, local magistrates in England appointed two sanitary inspectors to oversee factory sanitation. These early inspectors, including a former cleric and a justice of the peace, played a crucial role in addressing the health and sanitation issues arising from industrialization.
The field of environmental health as we know it today can be traced back to the 1840s in England. Edwin Chadwick, a Poor Law Commissioner, conducted an inquiry into poverty's causes, highlighting the link between poor health and bad environmental conditions. Chadwick's campaign for improved sanitation led to the Public Health Act 1848 (11 & 12 Vict. c. 63), establishing a General Board of Health and allowing local boards to correct discovered issues based on an inspector's survey.
In 1883, the Association of Public Sanitary Inspectors, which later became the United Kingdom's Chartered Institute of Environmental Health, was established. This marked a significant development in the professionalization of the field. Over the following decades, the role and qualifications of environmental health practitioners evolved, transforming into a graduate profession by the 1960s. The profession's enhanced role and status were further recognized with the grant of a royal charter in 1984.
Reflecting the changes in their roles and educational requirements, the titles of these professionals have evolved over the years, from inspectors of nuisances to sanitary inspectors, and then to public health inspectors or environmental health officers. This progression also mirrors International Trends, as the titles and roles of environmental health officers have adapted to reflect their advanced education and expanding responsibilities.
Throughout history, Environmental Health Officers have been integral to public health, adapting their roles and expertise to meet the challenges of their times, from the spread of epidemics in Renaissance Venice to the complex public health needs of modern societies.[18][19][20]
Inspector of nuisances
"Inspector of Nuisances" was a title given to officials in various English-speaking jurisdictions, primarily associated with public health and sanitation from the mid-19th century onwards. While now considered archaic in many places, its historical significance remains notable.
The first Inspector of Nuisances appointed by a UK local authority health committee was Thomas Fresh in Liverpool in 1844. The role was formalized with the passage of the Nuisances Removal and Diseases Prevention Act 1855 and the Metropolis Management Act 1855, under the title 'Sanitary Inspector'. In jurisdictions with established boards of health, the title was 'Inspector of Nuisances'. Eventually, 'Sanitary Inspector' became the standardized title across all UK local authorities. In 1900 the Australian National Council of Women was drawing attention of the authorities to the success of women as sanitary inspectors in England appointed by Thomas Orme Dudfield.[21]
The job title in Britain was changed to 'Public Health Inspector' by an Act of Parliament in 1956. Similar offices hadbeen established throughout the British Empire.
In the modern context, the nearest equivalent in the UK is the 'Environmental Health Officer', a title adopted following the Local Government Act 1972, on the recommendation of the Central Government.
In the United States, an example of the continued use of the title 'Inspector of Nuisances', albeit with a different scope, is found in Section 3767 of the Ohio Revised Code. This defines the role as investigating nuisances broadly covering establishments associated with lewdness and alcohol. The environmental health role in US local authorities is typically undertaken by officers titled 'Registered Environmental Health Specialist' or 'Registered Sanitarian', depending on the jurisdiction. Within the US Public Health Service, these functions are carried out by commissioned (uniformed) 'Environmental Health Officers'.[1][22]

An emergency medical technician is a medical professional that provides emergency medical services. EMTs are most commonly found serving on ambulances and in fire departments in the US and Canada, as full-time and some part-time departments require their firefighters to at least be EMT certified.
A paramedic is a healthcare professional trained in the medical model, whose main role has historically been to respond to emergency calls for medical help outside of a hospital. Paramedics work as part of the emergency medical services (EMS), most often in ambulances. They also have roles in emergency medicine, primary care, transfer medicine and remote/offshore medicine. The scope of practice of a paramedic varies between countries, but generally includes autonomous decision making around the emergency care of patients.
The Occupational Safety and Health Administration is a regulatory agency of the United States Department of Labor that originally had federal visitorial powers to inspect and examine workplaces. The United States Congress established the agency under the Occupational Safety and Health Act, which President Richard M. Nixon signed into law on December 29, 1970. OSHA's mission is to "assure safe and healthy working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education, and assistance." The agency is also charged with enforcing a variety of whistleblower statutes and regulations. OSHA's workplace safety inspections have been shown to reduce injury rates and injury costs without adverse effects on employment, sales, credit ratings, or firm survival.
Environmental health is the branch of public health concerned with all aspects of the natural and built environment affecting human health. To effectively control factors that may affect health, the requirements that must be met to create a healthy environment must be determined. The major sub-disciplines of environmental health are environmental science, toxicology, environmental epidemiology, and environmental and occupational medicine.
A fire marshal, in the United States and Canada, is often a member of a state, provincial or territorial government, but may be part of a building department or a separate department altogether. Fire marshals' duties vary but usually include fire code enforcement or investigating fires for origin and cause. Fire marshals may be sworn law enforcement officers and are often experienced firefighters. In larger cities with substantially developed fire departments the local fire departments are sometimes delegated some of the duties of the fire marshal.
The National Institute for Occupational Safety and Health is the United States federal agency responsible for conducting research and making recommendations for the prevention of work-related injury and illness. NIOSH is part of the Centers for Disease Control and Prevention (CDC) within the U.S. Department of Health and Human Services. Despite its name, it is not part of either the National Institutes of Health nor OSHA. Its current director is John Howard.
Occupational hygiene or industrial hygiene (IH) is the anticipation, recognition, evaluation, control, and confirmation (ARECC) of protection from risks associated with exposures to hazards in, or arising from, the workplace that may result in injury, illness, impairment, or affect the well-being of workers and members of the community. These hazards or stressors are typically divided into the categories biological, chemical, physical, ergonomic and psychosocial. The risk of a health effect from a given stressor is a function of the hazard multiplied by the exposure to the individual or group. For chemicals, the hazard can be understood by the dose response profile most often based on toxicological studies or models. Occupational hygienists work closely with toxicologists (see Toxicology) for understanding chemical hazards, physicists (see Physics) for physical hazards, and physicians and microbiologists for biological hazards (see Microbiology, Tropical medicine, Infection). Environmental and occupational hygienists are considered experts in exposure science and exposure risk management. Depending on an individual's type of job, a hygienist will apply their exposure science expertise for the protection of workers, consumers and/or communities.
Nuisance is a common law tort. It means something which causes offence, annoyance, trouble or injury. A nuisance can be either public or private. A public nuisance was defined by English scholar Sir James Fitzjames Stephen as,
"an act not warranted by law, or an omission to discharge a legal duty, which act or omission obstructs or causes inconvenience or damage to the public in the exercise of rights common to all Her Majesty's subjects".
The Chartered Institute of Environmental Health (CIEH) is a professional membership body concerned with environmental health and promoting standards in the training and education of environmental health professionals.
The U.S. Army Veterinary Corps is a staff corps of the U.S. Army Medical Department (AMEDD) consisting of commissioned veterinary officers and Health Professions Scholarship Program (HPSP) veterinary students. It was established by an Act of Congress on 3 June 1916. Recognition of the need for veterinary expertise had been evolving since 1776 when General Washington directed that a "regiment of horse with a farrier" be raised. It has evolved to include sanitary food inspectors and animal healthcare specialists.
Hazardous Waste Operations and Emergency Response is a set of guidelines produced and maintained by the Occupational Safety and Health Administration which regulates hazardous waste operations and emergency services in the United States and its territories. With these guidelines, the U.S. government regulates hazardous wastes and dangerous goods from inception to disposal.

The field includes those who work as a nurse, physician, physician assistant, registered dietitian, veterinarian, veterinary technician, optometrist, pharmacist, pharmacy technician, medical assistant, physical therapist, occupational therapist, dentist, midwife, psychologist, audiologist, or healthcare scientist, or who perform services in allied health professions. Experts in public health and community health are also health professionals.
Right to know is a human right enshrined in law in several countries. UNESCO defines it as the right for people to "participate in an informed way in decisions that affect them, while also holding governments and others accountable". It pursues universal access to information as essential foundation of inclusive knowledge societies. It is often defined in the context of the right for people to know about their potential exposure to environmental conditions or substances that may cause illness or injury, but it can also refer more generally to freedom of information or informed consent.
Bioenvironmental Engineers (BEEs) within the United States Air Force (USAF) blend the understanding of fundamental engineering principles with a broad preventive medicine mission to identify, evaluate and recommend controls for hazards that could harm USAF Airmen, employees, and their families. The information from these evaluations help BEEs design control measures and make recommendations that prevent illness and injury across multiple specialty areas, to include: Occupational Health, Environmental Health, Radiation Safety, and Emergency Response. BEEs are provided both initial and advanced instruction at the United States Air Force School of Aerospace Medicine at Wright-Patterson Air Force Base in Dayton, Ohio.
Occupational health nursing is a specialty nursing practice that provides for and delivers health and safety programs and services to workers, worker populations, and community groups. The practice focuses on promotion, maintenance and restoration of health, prevention of illness and injury, and protection from work‐related and environmental hazards. Occupational health nurses (OHNs) aim to combine knowledge of health and business to balance safe and healthful work environments and a "healthy" bottom line.
Occupational safety and health (OSH) or occupational health and safety (OHS) is a multidisciplinary field concerned with the safety, health, and welfare of people at work. OSH is related to the fields of occupational medicine and occupational hygiene and aligns with workplace health promotion initiatives. OSH also protects all the general public who may be affected by the occupational environment.
In Sri Lanka, the Public Health Inspector (PHI) profession started in 1913. The PHI plays a crucial role in the public health sector for over a hundred years.
