Aspecto microbiológico e parasitológico de alface lisa (Lactuca sativa L.) produzida em sistema convencional por hortigranjeiros do sertão paraibano.

Abstract

Vegetables have been one of the most food-related food-borne outbreaks worldwide, especially as they have been implicated as vehicles of pathogenic microorganisms of public health significance. In this context, the objective of this work was to evaluate the microbiological and parasitological profile in lettuces of the Municipalities of Patos and Teixeira in the Paraíba hinterland. Microbiological and parasitological analyzes were carried out on 30 lettuce (Lactuca sativa L.) samples, 15 of which were collected on rural properties in the municipality of Patos and 15 in the municipality of Teixeira. Of this total, 60% (9) of the lettuce samples collected in the municipality of Patos were at unsatisfactory levels, while in the municipality of Teixeira 90% (14) 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.
