The work was focused on changes in the prevalence and numbers of Campylobacter sp. on processed broiler carcasses in Poland in the annual cycle. The subjects of the analysis were skin samples collected monthly directly from the poultry processing line, prior to the breast filleting production stage. The procedure used included simultaneous pre-enrichment and direct plate counting according to ISO 10272 (1995) with the detection level (1cfu g⁻¹), followed by biochemical identification of the species. For the strains identified biochemically as C. jejuni confirmation by the nested PCR method was done. The incidence rate of campylobacter contamination of processed broiler carcasses tested exceeded 88%, with numbers of Campylobacter sp. ranging from 10º to 10⁴ cfu g⁻¹ and C. jejuni being the most frequently isolated species. The differences in the incidence rate of campylobacter contamination of the skin of the processed broiler carcasses were statistically significant among the seasons and highly statistically significant among months. As for the campylobacter contamination level of processed poultry carcasses, variations in the numbers of the bacteria were statistically not significant among the seasons and highly significant for months, being visibly lower in June and the highest in July.
