The isolation rate of Campylobacter from the cecal contents of chickens at a poultry processing plant in Hiroshima Prefecture was 12% (13/108), and all of the isolates were identified as Campylobacter jejuni. After the chickens with Campylobacter-positive cecal contents (the carriers) were processed, the bacterium was also isolated from the surfaces of the carcasses and the chiller water. Conversely, after the chickens with Campylobacter-free cecal contents (the non-carriers) were processed, the bacterium was not isolated from either the carcasses' surfaces or the chiller water. The bacterium was isolated from the carcasses of the non-carriers when they were processed after the carriers, suggesting that cross-contamination resulted from the carriers. Since the bacterium was isolated from the carcasses after they were chilled, it appears to be difficult to eliminate Campylobacter contamination using the hygiene control system currently employed in poultry processing plants. On the other hand, cross-contamination was prevented by processing the non-carriers prior to the carriers (sectioned processing). We therefore suggested that sectioned processing is effective for preventing the cross-contamination of non-carriers with Campylobacter from carriers.
