Food safety concerns know no global boundaries. Information is disseminated daily, and even hourly via Internet, which describes concerns ranging from E. coli 0157:H7 in American beef to Listeria monocytogenes in Greek feta cheese. According to the CDC website (2002), an estimated 1.4 million cases of salmonellosis occur annually in the United States with an estimated 500 or more fatal cases each year. Although these numbers are rather staggering, Hedberg (2001) indicated that pork or pork containing foods were implicated as the source for only 3% of salmonellosis outbreaks reported by CDC from 1990-97. Sarwari et al. (2001) indicated that serotypes impacting human illness may not correlate as well as expected to those found in animals. There remains the question of variable virulence between types of Salmonella spp., which might cause one to reconsider treating all Salmonella as equals. Investigations into virulence of specific strains of Listeria monocytogenes and Campylobacter are being conducted as well.
