Surveillance study reveals high Campylobacter jejuni contamination across chicken processing plants, suggesting poultry intestinal colonization drives market product contamination.

Key Points

To determine the prevalence of Campylobacter jejuni and identify primary sites of cross-contamination within commercial chicken processing facilities.
Assessed two federally inspected processing facilities across four groups defined by bird age, plant site, and scald water temperatures (49°C, 53°C, and 60°C).
Collected samples from 12 distinct points along the processing line, including ceca, fecal matter, feather pickers, chilling tanks, and edible parts.
Campylobacter jejuni was isolated from 68% of ready-for-market poultry products and 60% to 100% of cecal samples, with fecal counts exceeding 10^6 organisms/g.
Scald water temperatures of 60°C did not reduce C. jejuni prevalence in edible cuts compared to 49°C or 53°C.
Feather pickers and chilling tanks served as primary sites of cross-contamination, with intestinal tract colonization correlating with final product contamination.
