Interpretive Summary:

Technical Abstract: The reduction of microbial pathogens in food products is the most pressing food safety problem today, and research is needed to elucidate the fundamentals of growth and survival of pathogens in situ. Our goal is to reduce the risk of foodborne disease by determining how pathogens interact within biofilms in processing environments and to use this information to develop effective intervention strategies that minimize contamination of products. Bacterial isolates from a poultry processing facility have been collected and identified. The resistance of the isolates to 10 therapeutic veterinary antibiotics was determined, and samples of pathogens of concern in poultry processing (e.g., Salmonella sp., E. coli, etc.) were analyzed for comparison. The antibiotics to which the most resistance was noted were penicillin G, sulfadimethoxine, and erythromycin whereas the least resistance was noted to enrofloxacin. Isolates exhibited multiple resistance to as many as 6 antibiotics, with a common resistance among gram-negative bacteria to the three antibiotics noted previously. Differences in resistance patterns occurred between gram-positive and gram-negative bacteria and between species within the same genus. The data will be used to select media to maintain, experimentally manipulate, and re-isolate specific organisms to study their interactions and characterize their role in biofilm development. Data from susceptibility testing of individual species will also give some indication of the antibiotics for which resistance may develop in biofilm communities and which may lead to resistance in pathogens released from these biofilms.
