ABSTRACT:
1. INTRODUCTION/CONTEXT
Brazil stands out as one of the largest producers of animal-derived foods. Its products are exported to over 180 countries, demonstrating the robustness of Brazil's official inspection services. In the third quarter of 2025 alone, Brazil slaughtered over 10 million head of cattle (IBGE, 2025). Regarding fish, according to the Brazilian Fish Farming Association (Peixe BR), farmed fish production in Brazil reached 968,745 tonnes in 2025 (Peixe BR, 2025). Even greater growth is projected, given that Brazil possesses the largest supply of available freshwater (Conab, 2021; FAO, 2018). In this context, ensuring microbiological safety throughout the food production chain is vital for maintaining the value of these products in both domestic and international markets and for avoiding trade embargoes. In general, animal-derived foods play a significant role in determining human exposure to biological or chemical contaminants (LIEVAART, 2005). Foodborne outbreaks involving fresh products occur due to the transfer of pathogens such as *E. coli* and *Salmonella* spp. via direct or cross-contamination with feces during processing; this is because products like meat and milk obtained from healthy animals are initially sterile—meaning any contamination originates from inadequate processing practices. Thus, effective control of these agents requires an integrated approach that encompasses the entire production chain (NORRUNG, 2009).
