Campylobacter in broiler flocks

The Norwegian Veterinary institute monitor the situation of Campylobacter in broiler flocks on assignment from the Norwegian Food Safety Authority.

Campylobacteriosis is currently the most commonly reported bacterial infectious disease in the Norwegian human population. In almost half of the cases, the infection is acquired in Norway. Consumption of poultry meat purchased raw has been identified as a significant risk factor together with the drinking of undisinfected water, eating at barbecues, occupational exposure to animals, and eating undercooked pork (Kapperud et al. 2003, Am J Epidemiol, 158:234-242).

The files called Handlingsplan is the action plan of the surveillance program, and is only available in Norwegian. 


Surveillance in 2017 showed that a total of 136 flocks (7.1%) tested positive for Campylobacter spp. when all broiler flocks slaughtered before 51 days of age during the period May – October were tested. In total 1,919 flocks from 521 farms were sampled. There are regional differences in the proportions of positive farms. Of the positive flocks, 42.6% originated from 5.0% of the farms. The carcasses from the positive flocks were either heat treated or frozen for a minimum of three weeks before being marketed. This year’s result is nearly the same as in 2016, which was the least favourable since 2009. The prevalence is still very low though, compared to most other European countries.
