Integrating animal health and foodborne disease surveillance. (Special Issue: Coordinating surveillance policies in animal health and food safety 'from farm to fork'.)

摘要

The control of foodborne diseases from an animal source has become an important part of public health policy. Since the agents that cause these diseases originate in animals, Veterinary Services, as well as Public Health Services, must be involved in their control. Control programmes should be established either through cooperation between the two Services or by the consolidation of all those involved into a single food control agency. Surveillance is an important part of these control programmes. The following questions must be addressed when planning an effective surveillance programme. What is the relative incidence, morbidity, mortality and economic cost of the foodborne disease in humans Is the animal population the exclusive or a significant source of the human foodborne infection What kind of surveillance is needed to identify the disease-causing agent in the animal population Are we interested in identifying all cases of a disease in order to eradicate it or is our aim to reduce its incidence in the animal population Do we have the ability to control the disease in the animal population What disease detection tests are available What are the sensitivity, specificity and cost of these diagnostic tests Finally, does the country, region or agency involved have the legal, financial and educational resources to carry out this surveillance and follow it up with appropriate action After these questions have been resolved, the veterinary and public health sectors must jointly decide if surveillance and control are feasible. If so, they can then begin to develop an appropriate programme.
