Animal health and welfare

As is the case for humans, animal health can be threatened by various viruses, bacteria and parasites. ANSES's expertise offers insights into the complex interactions between pathogens, animals and rearing conditions, while supporting the management of health crises. It therefore contributes to prevention and control of the main animal diseases affecting livestock and wildlife, as well as the zoonoses affecting human health. It also works to improve animal welfare while ensuring the safety of the food chain and the sustainability of the different production sectors.
