ABSTRACT
Objective:
To determine the prevalence of Salmonella species during slaughtering and dressing of broiler chickens at four poultry processing plants in Trinidad using three isolation methods. Design andMethodology:
In this cross-sectional study, a total of 396 samples were collected from all four commercial poultry processing plants in Trinidad. Samples collected comprised swabs of cloacae pre-slaughter, pre evisceration and post evisceration carcasses; immersion chiller water, neck skins, whole carcasses and chicken parts (final product). Isolation and identification of Salmonella spp. were performed using standard bacteriological techniques (whole carcass enrichment, whole carcass rinse and neck skin methods).Results:
The overall prevalence of Salmonella spp. was 27.5% (109/396). The prevalence of Salmonella spp. was 2.2% (2/90), 55.6% (25/45), 37.8% (17/45), 27.8% (25/90), 5.6% (2/36), 44.4% (20/45) and 40.0% (18/45) for cloacal swabs, preevisceration carcasses, post evisceration carcass swabs, neck skins, immersion chiller water, whole carcass and chicken parts respectively (p<0.001). Salmonella was isolated from 52.3% (46/88), 19.3% (34/176), 11.4% (5/44) and 27.3% (24/88) of the samples from Plant A, B, C and D respectively (p<0.001). Overall, Salmonella was detected in 27.2% (49/180), 27.8% (25/90) and 39.4% (71/180) carcasses by whole carcass rinse, neck skin method and whole carcass enrichment method respectively (p= 0.028).Conclusion:
Data from the study indicate the extent of contamination by Salmonella spp. throughout the various stages of broiler processing at the four plants studied and, of significance is the risk of salmonellosis posed to consumers of contaminated, undercooked chicken sold to retail outlets by these processing plants in the country.
