Informal fish marketing is an important source of food and income for many families. However, it is also a public health issue, since the quality of fish can be compromised during marketing. The microbiological quality of fish sold in town fairs in the municipalities of the Bahia Reconcavo region, Brazil, was assessed to characterize isolates based on antimicrobial susceptibility and to investigate gene virulence. Samples of mullets (Mugil sp.), mussels (Mytella sp.), and mollusks (Anomalocardia brasiliana) were collected in town fairs in the municipalities of Cachoeira, Cruz das Almas, and Santo Ant ?nio de Jesus. The presence of mesophylls, molds and yeasts, total coliforms, Escherichia coli, and Staphylococcus aureus was evaluated. E. coli and S. aureus isolates were subjected to antimicrobial susceptibility tests and the presence of the gene stx in E. coli isolates was investigated. Total coliforms and S. aureus ranged between 0 and 9.50 log CFU/g, while high counts of mesophylls, molds, and yeasts were detected. E. coli had greater resistance (76.8%) to amoxicillin and S. aureus had greater sensitivity to gentamicin. The stx gene was not identified in any of the samples studied. Results showed that some fish sold in the town fairs of the three municipalities possessed unsatisfactory microbiological quality, which may pose risks to consumer health, and may be vectors for the dissemination of bacteria resistant to different antimicrobial agents.

Tuberculosis and Cysticercosis in Brazil: A Review

引用

Food and Nutrition Sciences 2018年第6期9卷 642-662页

Tuberculosis and the taeniasis-cysticercosis complex, typical cases of zoonosis, have great importance for public health, since they cause economic liabilities to the Brazilian beef production chain. They are actually a synonym of technical inadequateness in Good Production Practices. Both diseases have existed since ancient times and their occurrence should be controlled by basic sanitary measures. However, there is a significant neglect attitude by authorities of countries with high occurrence rates, or rather, tropical underdeveloped nations, to focus on public policies for the control and decrease of the prevalence and the occurrence of these diseases. Current review elucidates the epidemiological profile of the diseases and contributes towards the elucidation and establishment of measures ensuring control.
