Investigation of public health issues by regional field disease investigation units

The conventional means of delivering animal health services to agricultural animal producers (private veterinary practitioners and state animal disease diagnostic laboratories) leave a gap where important regional disease problems are inefficiently addressed. This gap was successfully targeted by Dr. Clive Gay in the development of the Field Disease Investigation Unit (FDIU) for the northwestern region of the United States. The FDIU has also successfully targeted several zoonotic public health concerns and its success demonstrates the existence of a similar gap in the investigation and control of important public health issues including disseminated Salmonella clones and emergence of antimicrobial resistance.
