Condições higiênico-sanitárias de uma indústria de processamento de conservas de polpa de pequi na região norte do Estado de Minas Gerais

Abstract

An evaluation of the hygienic-sanitary conditions of a processing industry of pequi (Caryocar brasiliense Camb.) pulp preserve located in the northern area of the state of Minas Gerais was accomplished. The microbial load of the pulp of the fruit in natura, the freshly detached pulp, the pulp stored after the bleaching, hands of handlers, surfaces in contact with the pulp, air, and water were evaluated. The following analysis were carried out: total aerobic mesophilic bacteria, yeast and mould, enterobacteria, total coliform and coliform bacteria at 45ºC, as well as the research of bacteria potentially pathogenic, such as Salmonella spp. and Staphylococcus coagulase positive. In variable proportions, the presence of indicators of fecal contamination, pathogenic and spoilage microorganisms were verified. Inefficiency of the procedures of personal hygiene and sanitization of the manipulation surfaces were demonstrated. The water used by the industry was in non-conformance with the bacteriological standards required by the Brazilian legislation. The results alert for the need of implementation of a microbiologic monitoring system in the processing area of pequi pulp preserves, including equipments, utensils, surfaces, air, water and handlers. The implementation of Good Manufacturing Practices will be an essential tool for the evaluated industry to guarantee the safety of the final product.
