Análise parasitológica e microbiológica em alface crespa produzidas por hortigranjeiros do Sertão da Paraíba.

Abstract

Contamination of food has become a relevant topic for the moment, since many foods are consumed in natura, such as fruits, vegetables and vegetables, and need to be studied the real microbiological and parasitological situations of these foods, so that the final consumer does not suffer With possible pathologies, including serious infections, that may arise from the consumption of contaminated food. In this context, the objective of this work was to evaluate the microbiological and parasitological profile in lettuces of the municipalities of Teixeira and Patos in the Paraíba hinterland. Microbiological and parasitological analyzes were carried out on 30 lettuce samples (Lactuca sativa), 15 of which were collected on rural properties in the municipality of Teixeira and 15 in the municipality of Patos. From this total, it was found that 40% (6) of the lettuce samples collected in the municipality of Teixeira were at unsatisfactory levels, while in the municipality of Patos 80% (12) were satisfactory to consumption according to Resolution - RDC No. 12 Of January 2, 2001 of the National Agency of Sanitary Surveillance - ANVISA, which recommends raw vegetables, prepared for direct consumption, can not contain Salmonella spp / 25g of the product and thermotolerant Coliforms above 10² CFU / g. Samples from both municipalities presented immature forms of nematodes and protozoa and it was found that the lettuce samples were contaminated by structures of parasites of dogs such as Toxocara spp. and Ancylostoma spp. and protozoa such as Giardia and Toxoplasma. Further studies are needed to track the entire production system, consisting of analyzing the quality of the water used for irrigation, the amount of inputs (organic matter), hygiene and the orientation of the manipulators.
