We classified commercial chickens as general broiler (General), Meigara-brand (Meigara), and Jidori-Japanese native (Jidori), and investigated contamination with Campylobacter spp. (C spp.) and Listeria spp. (L spp.). We isolated C spp. from 57 of 90 samples and C. jejuni from more than 50% of Jidori and Meigara chickens. We found that the amount of contamination with C. coli was less than half that of C. jejuni. L spp. was isolated from 49 of 65 samples. The segregation rates of both C spp. and L spp. were high for Jidori and Meigara, but low for General. We isolated both C spp. and L spp. from 43% of the samples. The number of samples in which only L spp. was isolated was three times greater than in the number of samples in which only C spp. was isolated. In terms of bacterial species, combined contamination with C. jejuni and L. innocua was most common. This study showed possible differences in the contamination level among Jidori, Meigara, and General chickens.
