Food insecurity, restrictions on poultry imports, rising protein needs, and the search for alternative sources of income have driven a rapid increase in backyard poultry farming across Nigeria. While this trend reflects resilience and enterprise, it has also resulted in the indiscriminate siting of poultry farms in residential areas, often without regard for public health, environmental safety, or biosecurity standards.
Across many states in the country, backyard poultry farms are commonly located within residential neighbourhoods, in some cases less than ten metres from homes. Alarmingly, most of these farms operate without basic biosafety measures. This situation persists largely because Nigeria lacks clear national or local regulations on locational clearance for poultry farms, allowing unsafe practices to become normalised.
Although the Food and Agriculture Organization (FAO) has not prescribed a universal international distance standard, it strongly advises countries to establish national guidelines based on health and environmental considerations. Key factors include topography, proximity to water sources and homes, climate, humidity, and rainfall. Countries such as India and Indonesia, which share similar socio-economic contexts with Nigeria, enforce a minimum distance of 500 metres between poultry farms and residential buildings. Nigeria has yet to adopt such safeguards.The siting of poultry farms close to homes poses serious risks to human health and quality of life. Common nuisances include foul odours that can travel several kilometres depending on weather conditions and waste management practices. Backyard farms also contribute to noise pollution and attract reptiles like snakes, drawn by birds and eggs, creating additional safety hazards.
More critically, poultry farming carries a high risk of zoonotic diseases, including avian influenza, Newcastle disease, fowl pox, Gumboro disease, and avian encephalomyelitis. The growing frequency of emerging and re-emerging animal-to-human diseases has become a major global health concern, with poultry identified as a significant reservoir.Nigeria has experienced multiple outbreaks of highly pathogenic avian influenza (HPAI) over the past decade.
Key drivers of these outbreaks include poor biosecurity practices, indiscriminate siting of farms and live bird markets, uncontrolled movement of birds across regions, and limited knowledge of biosafety among backyard farmers. In many cases, bird droppings are left to accumulate for days or weeks, stored in bags for sale as manure, or openly burned.These practices release offensive odours and harmful pollutants, contaminate the air with pathogens and increase the risk of respiratory infections, including walking pneumonia in humans. Poultry waste also contributes to climate change through emissions of methane, nitrous oxide, and carbon dioxide, especially when burnt openly.
Prolonged exposure to these pollutants can cause respiratory irritation, chronic illnesses, and allergic reactions. Noise from densely kept birds further disrupts sleep, increasing the risk of conditions such as hypertension, heart disease, diabetes, and obesity.
Nigeria cannot afford to compromise public health in its quest to meet growing protein needs. There is therefore an urgent need for coordinated action. The Federal Ministries of Health, Livestock Development, and Environment, working with agencies such as the Environmental Health Council of Nigeria, the Nigeria Institute of Animal Science, NESREA, and the Standards Organisation of Nigeria, should convene a stakeholders’ forum to establish national standards for locational clearance, minimum biosafety requirements, and basic competency levels for poultry farmers.In the interim, intensified public education, routine sanitary inspections, proper waste handling, and simple mitigation measures such as windbreak planting can help reduce risks.
Safe poultry production is achievable, but only through clear regulation, sustained awareness, and responsible practices that protect both livelihoods and public health.
