Data by the Pan-American Health Organization show that the death of about two million people a year and over 200 types of diseases are associated with increasing food contamination. Several types of technology and extensive legislation have been developed and targeted to this issue to reduce food microbiological load to safer levels and meet the expectations of increasingly demanding consumers. Current research investigates the process of sanitization of equipment and utensils in the fish industry by microbiological analyses. The study was conducted in a fish industry, installed in São Roque, State of São Paulo, Brazil. Swab technique was employed prior to cleaning and after sanitizing. Microbiological analysis comprised total counts of coliforms, fecal coliforms, psychrotrophic bacteria, mesophylls and Pseudomonas. In present study, microbiological analysis available in compendium of methods for the microbiological examinations of foods were useful for establish possible contamination by microorganisms. Correct sanitization throughout the manufacturing process has been targeted to maintain the quality and safety of the final product. Satisfactory results of present study may contribute to the discussion about standardization of sanitary procedures for fishing industry. Further research on the fishery industry should be undertaken to establish reliable standards to be employed nationwide.
