| Abstract: | The prevalence of Campylobacter in chicken sold at “pluck shops” in Trinidad was investigated. “Pluck shops” were classified as medium or low sale and samples were collected from 6 counties in Trinidad. Swab samples of cloacae of birds before slaughter and the carcass surfaces after processing, were plated on blood-free Campylobacter agar base containing CCDA Selective Supplement and plates incubated at 42°C in 8% CO2 for 48 h. Of the 645 of each type of sample collected, 517 (80.2%) and 541 (83.9%) of the cloacal and carcass samples, respectively, were positive for Campylobacter spp. Campylobacter was recovered from 519 (81.1%) of 640 samples taken from medium-sale shops and from 539 (82.9%) of 650 samples from low-sale shops. The prevalence of Campylobacter was statistically significantly different when related to the length of time a bird is kept in the shop (p=0.03) and the location of carcass for sale (p=0.02). The frequency of Campylobacter in chickens sold at “pluck shops” in Trinidad is high and poses a potential health risk to the consumer. The need to institute sanitary conditions at these establishments cannot be over-emphasized. |
