Foodborne diseases represent a major risk to public health worldwide. Pathogenic bacteria can live in the form of biofilm within food industry, providing permanent source contamination. The aim this study was evaluate influence types adhesion surfaces on Salmonella formation at eight different times, and analyze action time bacteriophage pool established biofilms. Most samples used were classified as weak producers, with serovars Enteritidis Heidelberg showing highest frequency formation. Glass stainless steel significantly favored 60 36 h incubation respectively, but polyvinyl chloride surface did not favor production, suggesting that type material may interfere production. period focused 3 h, treatment 9 glass biofilms superior other treatments because it affected largest number samples. These results suggests some serotypes promote indicate bacteriophages an alternative control But further studies are required prove effectiveness safety therapy antimicrobial processing plants.
