as a sentinel in the assessment of antimicrobial resistance in the tilapia production chain: from production environment to the final product.

Introduction: The intensification of tilapia production has increased animal density in tanks, leading to more frequent exposure to pathogenic agents and compromising the quality of fish products. Antimicrobial resistance is a global concern that affects human treatment, and sentinel microorganisms like are crucial for monitoring production chains, especially in aquaculture, where research is still limited. The aim of this study was to identify the presence of and investigate its antimicrobial resistance profiles throughout the entire tilapia production chain.

Microbiological assessment at slaughter of chicken carcasses from commercial, backyard and semi-backyard production systems.

Introduction: Smaller scale, alternative, chicken production systems are gaining popularity globally. However, this brings public health and market confidence concerns, especially where there are no established standards of production. The aim of this study was to carry out a microbiological analysis of chicken carcasses from the commercial, backyard and semi-backyard production systems, slaughtered in the same slaughterhouse.
