title: Seasonal variation in Campylobacter-contaminated retail chicken products: a year-round investigation in Japan.
abstract: Campylobacter was isolated from retail meat samples collected during the fiscal year 2009 in Japan. The higher percentages of contamination of chicken products were observed from June (39.3%) to November (83.3%). However, the highest number of human campylobacteriosis cases was reported in June in the Infectious Agents Surveillance Report. The chicken isolates with distinct clusters IVb and I, based on the restriction fragment length polymorphism of the flaA gene, were predominantly obtained during the periods between April and November 2009 and between February and March 2010, respectively. Extensive monitoring of Campylobacter contamination in chickens produced in various places is needed to analyse the seasonal variations between contamination of the meat products and the number of human cases with campylobacteriosis.
