Contamination of meat with Campylobacter jejuni in Saitama, Japan.
To determine the source of food contamination with Campylobacter jejuni, we investigated retail meat, a chicken processing plant and a broiler farm. C. jejuni was found in domestic retailed poultry (45.8%) and imported poultry (3.7%), but not in beef or pork. In the poultry processing plant, there is significant contamination with C. jejuni in chicken carcasses, equipment and workers' hands. This contamination increases during the defeathering and evisceration processes. RAPD analysis shows that contamination with C. jejuni is of intestinal origin. In a broiler farm, C. jejuni was first isolated from a faecal sample of broiler chicken after the 20th day of age. Two weeks later, all birds in this farm became C. jejuni positive. RAPD analysis indicated that C. jejuni spread rapidly from one broiler flock to the other flocks on the farm.
