Qualidade microbiológica e parasitológica de açaí na tigela comercializado em lanchonetes

Abstract

Abstract: We evaluated the microbiological and parasitological quality acai in the bowl sold in coffee shops in a city of Bahia Reconcavo. 15 samples were collected in five separate establishments. Held application of a checklist (checklist), to evaluate the sanitary conditions of sale sites, microbiological analysis for the quantification of indicator organisms, total coliforms and Escherichia coli (E. coli) and parasitological for research protozoan cysts, eggs or larvae of helminths. Considering the handling of food, mismatch was found in the handler apparel (53.33%), followed by long nails and enamel (46.66%). Although there is in law a standard for total coliforms, the population of this group ranged from 1.5 log UFC / g to 3.3 log UFC / g, with a mean of 1.93 log UFC / g, and 66.7% of the analyzed samples showed microbial population above 2 log UFC / g, indicating possible poor hygiene during processing and storage of the product. All the samples tested showed populations below 1 log UFC / g Escherichia coli. The parasitological analysis revealed absence of protozoan cysts, eggs or larval helminths and the presence of adult mites and fungi in two samples at two different points of sale. It follows that the existence of handling failures, and high populations of coliforms and against mites and fungi, highlights the need for training of handlers on Good Handling Practices for the safe production of acai in the bowl sold in cafeterias.
