Abstract

VENTURA-RAMON, G.H et al. Detection of Salmonella spp. in beef from TIF and non-TIF slaughterhouses in Nayarit, Mexico. Revista bio ciencias [online]. 2020, vol.7, e902.  Epub Nov 18, 2020. ISSN 2007-3380.  https://doi.org/10.15741/revbio.07.e902.

In Mexico, beef for human consumption comes from federal-inspection type (TIF, tipo inspección federal) or non-TIF slaughterhouses. The latter do not comply with all national quality and hygiene standards established by the Ministry of Agriculture and Rural Development (SADER, Secretaría de Agricultura y Desarrollo Rural), while TIF beef is certified by the National Service of Health, Safety, and Food Quality (SENASICA, Servicio Nacional de Sanidad, Inocuidad y Calidad Agroalimentaria), which reports to SADER. In this work the presence of Salmonella spp. was analyzed in TIF and non-TIF beef commercialized in supermarkets, as well as non-TIF beef commercialized in local butchers in Tepic, Nayarit (Mexico). Salmonella spp. was detected using qPCR, and the results indicate its presence in the three types of beef analyzed. Although a smaller proportion of contaminated samples and a lower degree of contamination were detected in it, TIF beef is not free from the presence of this pathogen and thus cannot be considered an innocuous product.
