Meeting Abstract. Volume 1: Page 1; CIRMS; Gaithersburg, MD 4/18 - 4/20/16. Interpretive Summary: Technical Abstract: In recent years understanding the role of foodborne pathogens in human disease has evolved to include conditions outside the gastrointestinal diseases typically associated with bacteria such as Salmonella, Shiga toxin-producing Escherichia coli (STEC), Listeria monocytogenes, etc. Other human pathogens have recently emerged which are globally disseminated in the environment, wild and food animals, produce, and meat and poultry such as Extraintestinal pathogenic E. coli (ExPEC), Staphylococcus saprophyticus, and Klebsiella pneumoniae which can colonize in the GI tract after consumption and cause urinary tract infections, cystitis, kidney infections, sepsis, and meningitis when contaminated human feces are accidentally transferred to other body parts such as the urethra. Deaths associated with these pathogens in the US are significantly higher than those associated with the typical diarrheal foodborne pathogens. Because the Centers for Disease Control and Prevention has recommended foods treated with food safety intervention technologies for “at risk” persons with underlying medical conditions we have determined the inactivation kinetics for ExPEC, S. saprophyticus, and K. pneumoniae suspended in poultry meat and purge using a variety of intervention technologies including gamma radiation, high pressure processing, ultraviolet light, and thermal processing. In this presentation the incidence and prevalence of these extraintestinal foodborne pathogens will be discussed. The data presented will include the inactivation kinetics for these pathogens in chicken meat and purge, as well as comparison to historical data for traditional intestinal foodborne pathogens such as the STEC and S. aureus. |
