New diseases of food animals are emerging at an increasing rate. Many of the same factors leading to emergence of human diseases are responsible for the emergence of animal diseases, and many of these diseases are zoonotic.
This presentation reviews recent examples of emerging diseases in food animals and discusses reasons for their emergence and dissemination. It suggests reasons for the increasing rate of emergence of food animal diseases and the implications of these diseases on public health and food security. Challenges in the control of zoonotic and non-zoonotic food animal diseases are described, and infrastructure changes needed to improve prevention and control of food animal diseases are listed.
