Qualidade microbiológica da ração seca para pet comercializada de forma a granel

Abstract

This study aimed to evaluate the microbiological quality of bulk pet food commercialized in different municipalities of the state of Alagoas, Brazil. Six samples were collected, including three cat food samples and three dog food samples, obtained in the municipalities of Satuba, Atalaia, and Maceió. Microbiological analyses were performed using the Most Probable Number (MPN) method to determine total coliforms, thermotolerant coliforms, and Escherichia coli, as well as the enumeration of fungi and yeasts in appropriate culture media. The results showed that five out of the six samples presented contamination by total coliforms. Sample 6 exhibited the highest thermotolerant coliform count (3.6 × 103 MPN g−1) and was classified as unacceptable according to ABINPET standards. Escherichia coli was detected in samples 2 and 4, while sample 4 showed the highest count of yeasts and molds (1.5 × 102 CFU g−1). Nevertheless, all samples complied with the established standards for aerobic mesophilic bacteria, yeasts, and molds. The findings highlight the need for proper storage and handling practices during the commercialization of bulk pet food in order to ensure animal food safety.
