“…They found that the average counts of mesophilic and psychrotrophic microorganisms were 5.4 × 10 7 and 1.1 × 10 11 , respectively. Additionally, in other regions of Brazil, studies have detected mussel samples with poor microbiological quality and the presence of potentially pathogenic agents [ 15 , 16 ]. This underscores the need for actions aimed at improving the quality of both seafood products, mussels and shrimp, in the commercial seafood market in Brazil, with shrimp samples being significantly more contaminated.…”

The consumption of seafood is crucial for food security, but poor hygiene along the food production chain can result in low microbiological quality, posing significant risks for public health and seafood quality. Thus, this study aimed to assess the microbiological quality and antimicrobial sensitivity of E. coli from 69 samples of illegally marketed shrimp and mussels in the Vitória Region, Brazil. These foods exhibited poor microbiological quality due to high counts of mesophilic, psychrotrophic, and enterobacteria microorganisms. While this issue is widespread in this area, shrimp samples displayed higher microbial counts compared to mussels, and fresh mussels had elevated counts of enterobacteria compared to frozen ones. Among the 10 E. coli isolates, none carried the genes blaCTX-M-1, blaCTX-M-2, blaCTX-M-3, blaCTX-M-15, mcr-1, mcr-2, mcr-3, mcr-4, and tet, associated with antibiotic resistance. Phenotypical resistance to tetracycline and fosfomycin was not observed in any isolate, while only 20% demonstrated resistance to ciprofloxacin. Regarding ampicillin and amoxicillin with clavulanic acid, 60% of isolates were resistant, 10% showed intermediate susceptibility, and 30% were sensitive. One isolate was considered simultaneously resistant to β-lactams and quinolones, and none were conserved as ESBL producers. These findings highlight the inherent risks to local public health that arise from consuming improperly prepared seafood in this area.

Bivalve molluscs are important fishing resources for human consumption around the world. However, for safe consumption, good hygiene conditions must be ensured throughout the production chain. Eating bivalve molluscs, particularly raw, can pose a significant health risk to consumers because they can act as vectors of infectious pathogens. This study aimed to evaluate the microbiological quality of mussels from Niterói, RJ and the use of cooking to ensure food safety, as well as assessing the susceptibility of Escherichia coli and coagulase-positive Staphylococcus strains to different antimicrobials. Therefore, microbiological analyzes were performed on mussels Perna perna before and after thermal processing, the impact of cooking on the microorganisms was verified. Cooking the mussels in water at 95°C for 1 (one) minute reduced product contamination. The use of the time x temperature binomial was sufficient to reduce pathogenic microorganisms to acceptable levels according to Brazilian legislation, although the pathogens were only completely eliminated after five minutes. The bacteria investigated had a high antibiotic resistance index: 66% of E. coli strains and 34.78% of coagulase-positive Staphylococcus strains were found to be resistant to multiple drugs.

O consumo de pescado é reconhecido como benéfico à saúde devido à sua composição rica em nutrientes, como proteínas, cálcio e fósforo. No entanto, sua alta perecibilidade exige rigoroso controle microbiológico. O sururu (Mytella strigata), molusco bivalve encontrado em manguezais, é vulnerável à contaminação por descarte inadequado de esgotos. Este estudo avaliou bactérias aeróbias psicrotróficas (BAP), aeróbias mesófilas (BAM) e Salmonella spp. em oito amostras de carne de sururu resfriada, coletadas em supermercados de São Luís - MA, durante dois meses de 2022. Todas as amostras apresentaram contagens de BAM abaixo do limite de 10⁷ UFC/g estabelecido pelo ICMSF (2018), enquanto 87,5% das amostras de BAP estavam dentro do limite de 10⁷ UFC/g (ICMSF, 2015). Uma amostra excedeu esse limite, indicando deterioração. Contudo, 25% das amostras testaram positivo para Salmonella spp., evidenciando risco à saúde pública. Os resultados reforçam a importância de monitoramento contínuo e de boas práticas no manuseio e comercialização do sururu.
