Excerpt
The need for the elaboration of strategies and methods for control of zoonoses and foodborne diseases was recognized by the Thirty-first World Health Assembly held in May 1978. In its resolution WHA31.48 on Prevention and control of zoonoses and foodborne disease due to animal products, the Assembly invited Member States to formulate and implement countrywide programmes for the control of these diseases as an integral part of national health programmes and requested the Director-General to promote the extension of a network of zoonoses centres in all regions, so that the necessary support can be provided to country health programmes. It also requested further development of national, regional and global strategies, and of methods for the surveillance, prevention and control of zoonoses and foodborne diseases.
