Technical Abstract: Recent studies have shown a significant presence of Campylobacter in the semen of mid-life and late-life roosters. The present study was done to determine if several foodborne pathogens (Campylobacter, Salmonella, Clostridium perfringens) could be isolated from the ductus deferens, testes and ceca of 45-65 week old commercial broiler breeder roosters. Five roosters from each of three separate commercial breeder farms were transported to the laboratory. Limited necropsy to remove ductus deferens, testes and ceca without contamination from blood and other tissues was carried out. All samples were analyzed for each of the three previously mentioned bacteria and for total aerobic bacteria, and Enterobacteriaceae. None of the three foodborne pathogens were isolated from the testes of any of the 15 commercial roosters. Clostridium perfringens was isolated from one of the 15 ductus deferens, while no Campylobacter or Salmonella were isolated from this tissue. Campylobacter was cultured from the ceca of all 15 roosters, Clostridium perfringens from 4/15, and Salmonella from 2/15. A quarter of all commercial broiler breeder's semen samples were found to be contaminated with Campylobacter in a previous study, however this organism along with Salmonella and Clostridium perfringens were not found in intra-abdominal tissues. Escherichia coli and Enterococcus faecium were occasionally cultured from the ductus deferens. The data suggest that the contamination of semen by these foodborne pathogens is a result of sources (cecal/fecal contamination) external to the testes and ductus deferens.
