Abstract

BARRIENTOS H, Edy Waldo et al. Presence of listeria monocytogenes in pig carcasses in Lima, Peru. Rev. investig. vet. Perú [online]. 2015, vol.26, n.1, pp.135-139. ISSN 1609-9117.  http://dx.doi.org/10.15381/rivep.v26i1.10907.

The aim of this study was to determine the presence of Listeria 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.

Keywords : carcasses; slaughterhouse; pigs; in situ hybridization.
