Perfil da qualidade de hortaliças fornecidas em creches públicas urbanas no Município de Patos-PB.

Abstract

The study evaluated the microbiological and parasitological quality of tomato (Solanum lycopersicum) and coriander (Coriandrum sativum) vegetables in 10 public urban day care centers in the city of Patos-PB, totaling 40 samples. Questionnaires were applied to cooks addressing issues of storage and hygiene of vegetables, use of personal protective equipment and personal hygiene. The most probable number of coliforms to thermotolerant (45°C / g) were evaluated; presence of Salmonella spp. and coagulase positive staphylococci; search for E. coli strains. The antibiogram verified the microbial activity of strains of Staphylococcus coagulase positive and Escherichia coli. The parasitological techniques used were spontaneous sedimentation and centrifugal flotation in zinc sulphate and evaluated qualitatively. The samples evaluated were unfit for human consumption because they had thermotolerant coliforms, 80% of coriander and 20% of tomatoes; Strains of E. coli were present in 40% of the nurseries surveyed, Staphylococcus coagulase positive in 78% and suggestive presence of Salmonella spp. by 80%. The parasitological evaluation verified the presence of Endolimax nana, Entamoeba histolytica / dispar, Giardia, Ascaris lumbricoides, Tenia, Dipylidium, Trichuris and Ancylosmota eggs. The antibiogram revealed a difference in sensitivity between strains of E. coli and Staphylococcus coagulase positive and the antibiotics tested. The result of the questionnaire showed that 11% of the cooks claimed to wear gloves; 22% reported wearing masks when they were ill; the use of props was affirmed in 44.5%; 22% were hygienic before storage; vegetables were stored with protection in 89% of day care centers and 11% of the vegetables had contact with the floor before being stored. It was noted that the absence of good manufacturing practices should be undertaken as a necessary measure for disease prevention, for this, public institutions should provide training courses, in addition to conducting periodic inspections.
