Sixty samples were collected between May and August 2016 at informal selling sites (fairs, butcher shops, abattoirs) and in supermarkets of ten municipalities of the Rec?ncavo da Bahia region. Hygiene and sanitary conditions were assessed through a check list. Total coliforms, Escherichia coli, mesophylls, psychrotrophic organisms, molds and yeast, and Salmonella spp. were counted. Results revealed statistical difference for total coliforms and Escherichia coli only, featuring greater concentration rates in fairs, butcher shops and abattoirs. Further, 31.7% of samples indicated 31.7% Salmonella spp. and 16.6% of samples failed to comply with sanitary legislation on Escherichia coli. Observational analysis demonstrated that 61.83% and 38.1% of the samples respectively on informal sites and in supermarkets did not comply with legislation and indicated a co-relationship of some variables with the growth of total coliforms, Escherichia coli and mesophylls. Pathogenic and indicator microorganisms suggest flaws in hygiene and sanitary conditions in the commercialization of chicken cuts and health risks to consumers.展开更多

One hundred and thirty-eight samples were collected during the dry and rainy periods in ten fish farms. Aeromonas spp. counts and tests for sensitiveness to antimicrobials were performed, coupled to the physical and chemical analyses of water. Tests revealed that 70% of samples were contaminated by Aeromonas spp., with water averaging 2.92 Log CFU/100 mL during the rainy period and 3.16 Log CFU/100 mL during the dry one. Fish contaminated by Aeromonas spp. averaged 2.58 Log CFU/100 mL during the rainy period and 3.53 Log CFU/100 mL during the dry one. Aeromonas spp. samples were multi-resistant to 2 or 8 antimicrobials in 62.5% of the samples. Ampicillin was the antimicrobial with the highest resistance percentage rate. Results showed that fish bred in amateur fish farms constituted a health risk for the population.展开更多

Even with technological innovations in the production, storage, and distribution of eggs, food poisoning continues to occur. Therefore, in the present study, we 1) evaluated the microbiological profile and the hygienic and sanitary quality of eggs commercialized in town fairs and markets and 2) verified whether there is any correlation between microbiological results and commercialization conditions. Thirty-six samples were collected from six municipalities in the region of Rec?ncavo from Bahia, Brazil. The hygienic and sanitary conditions were analyzed by quantifying the total coliforms, E. coli, mesophilic and psychrotrophic microorganisms, molds, and yeasts, and by the presence of Salmonella sp. The observational analysis showed that 91% and 68% of the samples in town fairs and markets, respectively, did not comply with the requirements of the current Brazilian legislation. There was no significant difference in the microbiological profile among samples from the fairs and markets. Several samples presented relevant significant values, indicating inadequate hygienic conditions and fecal contamination. Salmonella sp. was found in one sample. There was co-relationship between microorganism count and the variables “external dirt”, “external stains”, and “closeness to other products”, with high concentrations of total coliforms and E. coli in the non-conforming samples. Although no limits exist for mold and yeast counts, the presence of fungi makes the product unfit for consumption. Thus, the commercialization of eggs would benefit from more attention and supervision by the relevant authorities.展开更多
