Development and application of rapid PCR-based methods for the detection of potential human foodborne pathogens in livestock and turkeys. Pathogens of interest include Salmonella, Listeria monocytogenes, Campylobacter, Yersinia enterocolitica, and Arcobacter butzleri. Efforts are focused on-farm and post-slaughter.
