Detection of Salmonella sp in pork carcasses in slaughterhouses in Lima, Peru

Descripción del Articulo

The aim of this study was to detect the frequency of Salmonella sp by isolation techniques in pork carcasses intended for human consumption. Three hundred carcasses from two slaughterhouses in Lima, Peru were studied. Samples were taken by swabbing the skin of the head, abdomen, back and leg, repres...

Three hundred carcasses from two slaughterhouses in Lima, Peru were studied. Samples were taken by swabbing the skin of the head, abdomen, back and leg, representing 1200 subsamples. They were taken to the laboratory in Falcon tubes with buffered peptone water, and processed following the protocol for isolation of bacteria based on ISO 6579:2002. The isolates were identified by biochemical tests and specific antisera. In 6.3 ± 2.4% (19/300) of carcasses and 1.8% (21/1200) of subsamples were detected Salmonella sp. The highest frequencies of isolates were obtained from the head (33.3%, 7/21) and the abdomen (33.3%, 7/21). The isolates were serotyped and identified as Salmonella enterica subesp. enterica serotype Derby. The results confirm the need to implement control measures and detection of the bacteria to reduce the frequency of contaminated pork that reaches the consumer.El objetivo del presente estudio fue detectar la frecuencia de Salmonella sp, mediante técnicas de aislamiento, en carcasas porcinas destinadas al consumo humano. Se muestrearon 300 carcasas beneficiadas en dos camales de Lima Metropolitana, Perú. Las muestras fueron tomadas mediante hisopados sobre la piel de la cabeza, vientre, lomo y pierna, representando en total 1200 submuestras. Estas fueron transportadas al laboratorio en tubos Falcon con agua peptonada tamponada, donde fueron procesadas, siguiendo el protocolo de aislamiento bacteriano basado en la norma ISO 6579:2002. Los aislados fueron identificados mediante pruebas bioquímicas y antisueros específicos. En el 6.3 ± 2.4% (19/300) de las carcasas y en 1.8% (21/1200) de las submuestras se detectó la presencia de Salmonella sp.
