Abstract

Animal meals present potential for microbiological contamination, however they are still widely used in animal feeds. The objective of this study was to evaluate the microbiological quality of these meals processed in eight units distributed in the Minas Gerais state. Samples of viscera meals (248), meat and bone meals (224), and feather meals (216) were collected for microbiological evaluation from the receiving area of a feed mill located in the city of Viconde do Rio Branco, MG, Brazil. The results showed a high index of bacterial contamination of the species Salmonella sp. (5.3x102) and Staphylococcus sp. (4.5x105), total coliform (2.8x105), thermotolerant coliforns (3.3x105), total mesophiles (4.7x105), and fungi colonies (3.6x105). The animal meals processed in the unit “A” showed the highest levels of microbiological contamination. Additionally, the viscera meals were the by-products with lowest quality. Furthermore, processing units of animal meals cannot guarantee the microbiological control of products and may contaminate the fi nal feed. It was concluded that the animal meal does not meet the minimum quality for commercialization in feed mills.
