Abstract :
The prevalence of Salmonella spp. on broiler chicken carcasses and risk factors at the slaughterhouse were studied in 2008. A total of 425 carcasses were collected from 58 French poultry slaughterhouses over a 12-month period. Salmonella was isolated on 32 carcasses leading to a prevalence of 7.52% (CI95% = [5.01–10.05]). Thirteen different serotypes were identified. S. Indiana was the most prevalent serotype (33.3%) followed by S. Kottbus (13.9%); S. Enteritidis was isolated in only one batch (2.8%) and S. Typhimurium was not isolated on any sample. The enumeration performed on a subset of 219 samples using a miniaturized MPN technique, revealed very low numbers of Salmonella (1.6 and 110 cfu/g) in only 4 samples. The logistic regression analysis revealed 2 parameters as potential risk factors: (1) Gallus gallus as the sole species of poultry slaughtered in the slaughterhouse (OR = 7.08) and (2) less than 2 people present during evisceration (OR = 4.65).
