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.
