Zoonoses as a risk when handling livestock or animal products

The risk of zoonotic disease transmission when handling livestock or animal products is substantial. In industrialized countries, the classical zoonotic diseases such as tuberculosis or brucellosis are no longer in he foreground. Latent zoonoses such as salmonellosis and campylobacteriosis can cause serious disease in humans and have become a major public health problem during the past years. Since animals infected with these pathogens show only mild transient disease or no clinical signs at all, new concepts in the entire production line (<< stable to table >>) are necessary in order to avoid human infection. Two emerging viruses with zoonotic potential - avian influenza virus and Nipah virus - have been found in Asia in 1997 and 1999. Both diseases had a major impact on disease control and public health in the countries of origin. In order to cope threats from infectious diseases, in particular those of public health relevance, a combined effort among all institutions involved will be necessary. The proposed << European Center for Infectious Diseases >> and the << Swiss center for zoonotic diseases >> could be a potential approach in order to achieve this goal.
