Veterinary medicine in the 21st century: the challenge of biosecurity.
Review
Overview
abstract
The veterinary profession is presently challenged with developing and maintaining on-farm biosecurity protocols to protect the nation's food supply from acts of bioterrorism, from the growing threat of foreign animal diseases, and from multidrug resistance among pathogenic organisms. This challenge comes at a time when the supply of food animal veterinarians in the United States is progressively in decline, and raises the possibility that the profession is not adequately prepared to fulfill its responsibilities to the health and productivity of the US livestock and poultry populations. Causes of the decline in demand for veterinary services are discussed. They include consolidation of the food animal industries and a trend toward transferring performance of tasks traditionally carried out by veterinarians to the province of lay staff. This development potentially reduces veterinary surveillance of food animal populations. It also runs the risk of delay in recognizing and controlling serious health problems when they arise. Several remedies are proposed, including profound changes in the curriculum for educating food animal veterinarians to serve the consolidated but vulnerable livestock and poultry industries suitably. Also advocated is the initiation of training programs for herdsmen on the symptoms of foreign animal diseases, together with advice on when to call a veterinarian. Significant investment of federal or state resources will be required if these changes are to become reality.
