Uso de análise estatística para tomada de decisão: aplicação de métodos estatísticos para comparação de resultado microbiológicos de carcaças de frango de corte com e sem pigmentação na pele.

Abstract

Currently, Brazil is the largest exporter of poultry protein in the world, but the sector is impacted by economic losses arising from total and/or partial condemnations of poultry carcasses made by the Federal Inspection System (SIF), along the line of inspection, during the slaughter process. Faced with these challenges, the application of statistical tools is relevant, since most scientific hypotheses need to be validated to be accepted or rejected. The objective of this work was to apply the statistical tests of Analysis of Variance - one-way combined with the Tukey-Kramer test in order to compare microbiological results of carcasses of broilers with and without skin pigmentation, resulting from biliary contamination. This explanatory quantitative study was conducted in a chicken slaughterhouse, in the interior of São Paulo, Brazil. After applying the statistical tools, it was observed that the results of the microbiological analyzes performed on chicken carcasses with persistent skin pigmentation did not show a significant difference in relation to carcasses without pigmentation, with no need for total or partial condemnation of these carcasses.
