    • Tue, 06/21/2022 - 04:00
    • Oxytetracycline is an antibiotic authorized for use in aquaculture and is often detected in seafood products, especially shrimp. Previous studies investigating the fate of oxytetracycline in shrimp tissues after cooking were limited to quantification of parent compound residues, and did not describe any potential transformation products formed. Hence, the main objective of this study was to apply a non-target analysis workflow to study the fate of oxytetracycline in shrimp muscle.

  17. The CODEX Guidelines for Risk Analysis of Foodborne Antimicrobial Resistance are Incompatible with Available Surveillance Data

    • Tue, 06/21/2022 - 04:00
    • Foodborne antimicrobial resistant (AMR) microorganisms are a global food safety concern. Antimicrobial drug use (AMU) in livestock may increase the risk of resistant foodborne bacterial infections in humans via contaminated animal products. Consequently, countries have implemented different livestock AMU restriction policies, opening the potential for trade disputes.

    • Frontiers in Microbiology
    • Hepatitis E virus (HEV) is an emerging zoonotic pathogen with multiple species and genotypes, which may be classified into human, animal, and zoonotic HEV. Codon usage bias of HEV remained unclear. This study aims to characterize the codon usage of HEV and elucidate the main drivers influencing the codon usage bias. A total of seven HEV genotypes, HEV-1 (human HEV), HEV-3 and HEV-4 (zoonotic HEV), HEV-8, HEV-B, HEV-C1, and HEV-C2 (emerging animal HEV), were included in the study.

    • The biofilm community of microorganisms has been identified as the dominant mode of microbial growth in nature and a common characteristic of different microorganisms such as Pseudomonas aeruginosa, Staphylococcus aureus, and Staphylococcus epidermidis. The biofilm structure helps in the protection from environmental threats including host immune system and antimicrobial agents. Thus, the biofilm community has led to a higher prevalence of multidrug-resistant (MDR) strains in recent years.
