Technical Abstract: Salmonella are ubiquitous in nature and have been recovered from nearly all vertebrates (Taylor and McCoy 1969). Over 2,400 species have been identified. More cases of meat and poultry food borne disease are attributed to Salmonella or Campylobacter than any other agent (USDA: APHIS 1990). In a study of food borne disease from 1977 to 1984, Bryan (1998) observed that pork was responsible for 11% of the Salmonella outbreaks attributed to meat. Lammerding et al. (1988) recovered Salmonella from a number of different animal carcasses at slaughter. While the impact on the consumer is manifested after consumption of contaminated foods, the problem begins with infected animals on the farm.
