Technical Abstract: In recent years it has become apparent that emerging foodborne pathogens including Extraintestinal Pathogenic Escherichia coli (ExPEC), Staphylococcus saprophyticus, and Klebsiella pneumoniae are associated with human health conditions such as inflammatory bowel disease (IBD), ulcerative colitis (UC), and urinary tract infections (UTI). IBD and UC affect more than 3.5 million people in the United States and European Union annually, and represent a major global health problem. UTI affect more than 150 million people worldwide and are responsible for ca. 10 million physician’s office visits in the US. ExPEC is responsible for ca. 75% of UTI while and S. saprophyticus is responsible for an additional 6%. The economic cost of these diseases (IBD, UC, UTI are ca. $7 billion annually in the US alone. While the fraction of these infections directly linked to food contamination is not certain, the public health threat is certainly greater than that from more typically recognized foodborne pathogens. In our research we present the inactivation kinetics for ExPEC, S. saprophyticus, and K. pneumonaie in meat and poultry purge, iceberg lettuce, and spinach using a variety of food safety intervention technologies including thermal inactivation, high pressure processing, ionizing radiation, and light-based technologies.
