Abstract

Fecal samples from beef cattle (n=75), swine (n=105) and broiler chicken (n=32) and samples of ground beef (n=50) and ground pork (n=50) were examined for isolation of Arcobacter, Campylobacter, and Salmonella. Arcobacter spp. were isolated from 4.0% of cattle, 23.8% of swine, and 62.5% of chicken fecal samples; Campylobacter spp. from 76.0% of cattle, 63.8% of swine, and 50.0% of chicken fecal samples; Salmonella spp. from 0.0% of cattle, 3.8% of swine, and 53.1% of chicken fecal samples. All isolates detected from Campylobacter-positive cattle and chicken fecal samples were C. jejuni. Those from swine fecal samples were 97.0% C. coli and 3.0% C. jejuni. Ground-meat samples harbored no Campylobacter or Salmonella, although Arcobacter were isolated from 20.0% of the ground pork and 6.0% of the ground beef. A. buzleri was the most prevalent species in the Arcobacter-positive samples. S. Infantis was the predominant serovar in both swine and chicken fecal samples. These results indicate that fecal samples of livestock may be a potential vehicle for transmitting food poisoning caused by Arcobacter, Campylobacter and Salmonella.
