Abstract
Campylobacter fetus subsp. jejuni was commonly present in the feces of unweaned calves (2 to 3 weeks old) and from two of four groups of sheep. One new season lamb (12 to 16 weeks old) carried the organism, but the bacteria were not isolated from cattle. With unweaned calves, the fractions of animals infected and carcasses contaminated were similar. Contamination of carcasses usually involved low densities of C. fetus subsp. jejuni (ca. 1 to 10/cm2), which were isolated from flank but not rump areas. The organism was recovered less frequently from chilled carcasses and deboned veal. Small numbers of C. fetus subsp. jejuni could be recovered from equipment during the processing of unweaned calves but not after routine cleaning.
