Controle da qualidade sanitária em frigorífico de suínos do Paraná

Abstract

Maintaining hygienic conditions in food production is considered a key part of obtaining safety food. The aim of the present work was to elaborate the criteria to increase the control of the sanitary quality in equipment and utensils of a pork abattoir in Paraná. The development of the work began with the analysis of the microbiological results of the collection of swabs in equipment and tools of the process after the hygiene, following the standards of the companies authorized to export. Based on the concepts of the standards that concern the sanitary conditions in the productive environments, as well as the existing bibliography, a scale of evaluation of the conditions favorable to hygiene in equipment and utensils of the process was elaborated and applied. The results of the microbiological evaluations showed a 75.54% compliance rate for aerobic mesophilic microorganisms and 88.96% for enterobacteria and a prevalence of unacceptable results during the analyzed periods, specifically on conveyors. represent pockets of contamination and risk in the microbiological control of meat. The scale developed is composed of nine criteria that evaluate the characteristics favorable to hygiene and the operational characteristics of the process. The application of the scale indicates that the groups of conveyors and cutting equipment were those that presented the highest percentage of inadequacy to the criteria. Finally, the prevalence of enterobacteria was significant (p <0.01) (at the significance level of 5%) for the group of conveyors when compared to the other groups of equipment, so the differences in characteristics in the equipment can be related to the hygiene efficiency.
