Recent surveillance data indicates the prevalence of Campylobacter colonization among poultry populations in Norway. During the seasonal monitoring period from May to October 2025, the positivity rate among broiler flocks reached approximately 5%.
According to the findings, diagnostic screening identified 99 Campylobacter-positive flocks out of a total of 2,014 cohorts tested prior to slaughter, at less than 51 days of age. The comprehensive screening program included sample collection from 492 distinct poultry production facilities across the country.
These updated epidemiological metrics highlight a notable shift in the baseline distribution of the pathogen within the region’s commercial poultry sector, emphasizing the ongoing challenges of controlling foodborne pathogens at the primary production level. Carcasses from positive flocks were either heat-treated or frozen for a minimum of three weeks before being placed on the market.
This year’s prevalence of 4.9% falls within the range observed in previous years and remains comparatively low. The prevalence is also substantially lower than that reported in most other European countries.
