Interpretive Summary: Campylobacter bacteria are the main cause of human foodborne diseases. Therefore, an experiment was conducted to check for the presence of Campylobacter on chicken carcasses and in scald water taken from a chicken processing plant. Samples were collected from the plant from January through June, and the numbers of Campylobacter in scald water and on chickens taken from various processing steps was determined. The ability of the bacterium to survive on processed carcasses refrigerated for 7 or 14 days was also examined. A computerized, automated system was used to identify bacteria isolated from the samples. Results showed that no Campylobacter were recovered from samples collected in January or February, but the pathogen was recovered from samples collected in March, April, May, and June. Processing generally reduced the number of Campylobacter carried on the chickens, and the number of Campylobacter on the chickens generally decreased during refrigeration. Two different types of Campylobacter were recovered from the samples. Studies showed that poultry may carry different kinds of Campylobacter into processing plants and that the bacteria may be recovered from different processing operations. Campylobacter apparently is unable to survive in the processing facility between processing days however; therefore, the same group of bacteria is not able to contaminate broilers processed at later dates in the same plant.
