Prevalence of campylobacteria in the Finnish broiler chicken chain from the producer to the consumer

M Aho et al. Acta Vet Scand. 1988.

Abstract
in English, German

The prevalence of Campylobacter jejuni is 1.7 % (9/600) in the faeces of 4–5 week broiler chickens in Finland and 24 % (117/490) in the caeci of broiler chickens at slaughter. All waste waters at a processing plant, except water in a chlorinated (25 ppm) chilling tank, contained campylobacteria when a Campylobacter positive flock was slaughtered. Caeci contained mean logio 7.2 CFU campylobacteria/g. After chilling in a chlorinated ice–water tank there were still mean log10 4.5 CFU campylobacteria/carcass. Campylobacteria were detected from 7.0% (14/199) of deep–frozen broiler chicken carcasses at the market level. The concentration of C jejuni in naturally contaminated deep–frozen broiler chicken carcasses decreased by 2 log10 units in 4 weeks.

All prevalence figures were lower than in other developed countries outside Scandinavia. In Finland one of the reasons for low prevalence may be the extensive use of Nurmi cultures in Salmonella prevention programs.

Prevalensen av Campylobacter jejuni i Finland är 1.7 % (9/600) i avföring av 4–5 veckor gamla broilers och 24% (117/490) i caeci vid slakten. Alla avfallsvattenprov, med ett undantag av en klorerad avkylningstank (25 ppm), i produktionsinrättning innehöll campylobakterier när en campylobakterpositiv flock slaktades. Caeci innehöll log10 7.2 CFU campylobakterier/g (medelvärde). Efter avkylning i en klorerad isvattentank kunde log10 4.5 CFU campylobakterier isoleras från en kropp (medelvärde). På handelsnivå isolerades campylobakterier ur 7.0 % (14/199) av djupfrysta broilers. Förekomsten av campylobakterier hos naturligt kontaminerade djupfrysta broilers efter fyra veckors förvaring i −18°C var 2 log10 enheter lägre än hos kropparna strax efter slaktningen.

Alla prevalensvärden är mindre än i andra utvecklade länder med undantag av de skandinaviska länderna, kanske för att Nurmi kulturer användes allmänt för att bekämpa Salmonella i Finland.
