Qualidade bacteriológica de meias-carcaças bovinas oriundas de matadouros-frigoríficos do estado de Goiás habilitados para exportação

Resumo

Many are the bacteriological standards adopted by some countries to verify the quality of the imported bovine meat. Among these standards, in the most of these countries, bacteriological analyses are included as: counting and determination of the Most Probable Number (MPN) of the indicative microorganisms, besides counting and pathogen research. The present study aimed to evaluate the bacteriological quality of half-carcasses originated from slaughterhouse-freezers of Goiás State, Brazil, qualified to export, and to offer information so that the federal organs of regulation and inspection to specify standards for those meats. In this experiment, 160 half-carcasses bovine were appraised, hot and refrigerated, from June to September, 2004. The following analyses were accomplished: determination of the MPN of total Coliforms, fecal Coliforms and Escherichia coli; counting standard of aerobic mesophils microorganisms, strict or facultative, counting of psicrophiles microorganisms, counting of coagulasepositive Staphylococcus and counting of Clostridia sulfitereducer. The obtained results revealed that bacteriological quality of half-carcasses was acceptable for the main microorganisms to evaluate the “bacteriological status”, and, also, that there was no statistical difference among the results of the bacteriological analyses for both hot and refrigerated half-carcasses. However, there is a need of constant evaluation to improve industry’s quality control systems, in order to prevent that the alues, maintained in acceptable levels, as well as the effective bacteriological standards established by importer countries will not be xceeded.
