Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government what assessment they have made of the impact of large intensive chicken farms on human health, environmental standards, and animal welfare.

The Environment Agency assesses the environmental risk through the assessment of environmental permits to protect habitats from air pollution, and compliance with regulations to protect land and water. Measures are checked through regular compliance inspections.

There are a number of different farming systems in use in England and farms of all sizes have a role to play in promoting sustainable agriculture. All farms, regardless of size and type of production system, must comply with comprehensive legislation aimed at protecting animal health and welfare. The Government remains firmly committed to improving animal welfare and wants to work closely with the farming sector to deliver high standards. Ministers recently met with several representatives of various farming sectors to discuss the Animal Welfare Strategy. This outlines the Government’s plans to improve farm animal welfare including through transitioning away from intensive confinement systems such as cages or crates.

Ammonia from poultry farms contributes to fine particulate matter (PM2.5) pollution concentrations across the country. The precise contribution is difficult to assess and will vary according to the prevailing weather conditions and other sources of PM2.5. Long term exposure to fine particulate matter is associated with a number of serious health conditions. Intensive poultry farms with a capacity of 40,000 poultry places or more require a permit under the Environmental Permitting Regulations, to control their emissions into the environment.

Where animal welfare is impacted by farming practices, this can lead to increased health risks to humans through either the food chain, direct animal contact or through environmental contamination. For gastrointestinal disease this can occur through increased shedding of human pathogens where animals are at heightened stress, such as Salmonella spp and Campylobacter spp. Increased shedding of bacteria can also increase the risk antimicrobial resistance can spread.

Any individual exposed to positive detections of HPAI in poultry will be managed according to UKHSA’s public health guidance. Guidance for the management of people exposed to birds or other animals infected with influenza A(H5) - GOV.UK (copy attached).
