Qualidade microbiológica do ambiente, alimentos e água, em restaurantes da Ilha do Mel/PR

Abstract

Each year, several outbreaks of foodborne diseases are reported in Parana state, Brazil. Bacteria are responsible for 70% of these outbreaks and 95% of cases of food poisoning. There are reports that kitchen equipment and utensils contaminated have participated of approximately 16% of outbreaks. The aim of this study was to evaluate the microbiological quality of water, fresh foods, frozen foods, ready to eat food and sanitary conditions of three restaurants in Ilha do Mel - Paraná, Brazil, using PetrifilmTM. The results showed that 72.2% surfaces of had unsatisfactory sanitary conditions. Cutting boards, scrub sponge, kitchen sinks and dish towels had the highest average contamination. According to Brazilian law, samples of food outside of the standard were: seafood sauce, with 7,0 x 102 CFU/g of E. Coli, frozen mussels, with 7,0 x 102 CFU/g of E. coli; sample lettuce and grated carrot, considered clean, with 1,0 x 103 e 2,0 x 105 CFU/g of EC, respectively. All samples of food, in general, had high bacterial counts. Vegetables were the main responsible for the contamination of kitchen boards and sinks. The water used in the three restaurants had satisfactory microbiological quality. Better hygienic sanitary conditions were found in the restaurant where the employees had training in good manufacturing practices.
