The cost associated with food borne related illness in humans is estimated to be between $7.7 and $8.4 billion dollars annually and for the period 1973-1987 Salmonella accounted for 42% of the outbreaks and 51% of the cases (I). Pork was implicated as the food vehicle for 25 outbreaks during this period. In other studies (2), pork was responsible for II% of the Salmonella outbreaks attributed to meat. The presence of Salmonella spp. in meat animals has resulted in salmonellosis becoming the most important zoonosis in developed countries.
