Resumen:
We subtyped 32 Salmonella enterica strains isolated from carcasses (n = 10), theenvironment (n = 14), head meat (n = 1) and viscera washing and chilling water (n = 7) in provin-cial abattoirs with no Hazard Analysis Critical Control Point (HACCP) system from Buenos Aires,Argentina, before and after implementing improvement actions. Pulsed-field gel electrophore-sis (PFGE) was carried out using the XbaI restriction enzyme. Strains belonged to six serovars,from which 10 restriction patterns were obtained (five unique patterns and five clusters). Wefound different clones of S. enterica serovars in the same abattoir by XbaI-PFGE. In addition topromoting good hygiene practices, the implementation of an HACCP plan is necessary to meetthe zero-tolerance criteria for Salmonella on beef.
