Abstract

A study was performed with the aim to investigate associations between Campylobacter in chicken caecum, carcass skin, underlying breast muscle and packaged breast fillets. Samples were taken from 285 chickens from 57 flocks and analysed according to ISO 10272. Campylobacter spp. were isolated from caecal samples from 41 flocks. From birds of the same 41 flocks Campylobacter could be detected and quantified in 194 (68%) skin samples. Moreover, Campylobacter spp. were enumerated in 13 (5%) underlying muscle samples originating from 9 of the 41 flocks. The mean number of Campylobacter spp. in the 194 skin samples which could be counted was 2.3 log cfu/g and for the 13 underlying muscle samples 1.3 log cfu/g. Campylobacter could only be quantified in those breast muscle samples with a finding in corresponding skin sample. Five packaged chicken fillets were taken from each 25 of the 57 flocks and analysed both quantitatively and qualitatively. In qualitative analysis Campylobacter was detected in 79 (63%) fillets from 16 flocks and quantified in 24 (19%) samples from 11 flocks. The results showed a significant association (P < 0.05) between findings of Campylobacter on carcass skin (log cfu/g) and the proportion of Campylobacter pos...Continue Reading
