The aim of this study was to determine the presence ofListeria monocytogenes in pig carcasses in Lima, Peru. Samples were collected from the the surface of 88 carcasses in a slaughterhouse. Samples were enriched with BLEB medium and PALCAM broth. The pathogen was identified using the in situ hybridization molecular technique. The 13.9 ± 6.1% of carcasses were positive to L. monocytogenes, possibly due to deficiencies in the application and control of good manufacturing practices and standard sanitary operations in the slaughterhouse.
