Collaborative partners including four Universities (Ohio State, Minnesota, North Carolina State and Iowa State), industry and federal agency (USDA) conducted a one year on-farm monitoring project in swine production systems focusing on four major swine producing states: Iowa, North Carolina,…
Occurrence and molecular epidemiology of Methicillin Resistant Staphylococcus aureus (MRSA) on-farm, at slaughter and pork.
This study was conducted on ten conventional swine farms in Ohio to investigate the occurrence and prevalence of specific bacteria known to be resistant to methicillin called methicillin-resistant Staphylococcus aureus (MRSA) in pigs on-farm (before transportation), at lairage (after transportation),…
Genotyping of Campylobacter coli in Pigs from Farm to Fork
Campylobacter is a bacterial organism that causes 2.4 million foodborne illnesses annually in the United States. Pigs can be infected with these pathogens without symptoms, and fecal contamination of meat during processing could be of high food safety risk. The…
Analysis of in-plant Factors and Genotyping of Antimicrobial Resistance among Four Organisms Isolated from Swine Processing Plants
We investigated the role of factors within processing plants including environmental and body site sources for carriage of for food safety significant pathogens and dissemination of antimicrobial resistance factors among them. The objectives of the study were to determine the…
Epidemiology, Toxino- and Geno-typing of Clostridium difficile in swine at farm, slaughter and retail
We investigated the role of pigs in carrying important strains of C. difficile and the main goal was to determine the prevalence and compare strains of human and porcine origin. Samples were collected from swine farms in Ohio and North…
Serological Analysis of Toxoplasma gondii, Trichinella spiralis and Salmonella enterica among niche market antimicrobial-free and conventionally reared pigs
Three globally important zoonotic foodborne pathogens including Salmonella, Trichinella and Toxoplasma, were studied. Serological analysis of these pathogens was conducted on samples collected from two distinct pig production systems: antimicrobial-free, niche market type (ABF) and conventional (indoor-reared). The results from…
Development of a Microarray for the Rapid and Simultaneous Detection and Tracking of Bacterial and Viral Foodborne Pathogens
We developed a microarray for the rapid detection and characterization of three important bacterial pathogens including Campylobacter, Salmonella and Yersinia and a viral pathogen including Noroviruses. Probes that were printed on the glass slide were selected after analysis and through…
