Análises parasitárias e microbiológicas de hortifrútis no município de Juazeirinho - PB.

Abstract

The present study had the following objectives: 1) Determine the parasitological contamination of vegetables, Lettuce (Lactuca sativa) and Coriander (Coriandrum sativum).Twelve samples were collected from two different producers (7 coriander and 5 lettuce), which were analyzed by the spontaneous sedimentation method of Hooffman, Post and James or Lutz, through an electron microscope reading. Procedure repeated after two hours, for observation of the presence or absence of parasites. The species found were Ancylostoma spp, trematode oocyst, Cestodéo Echynococcus granulosus. 2 ° To evaluate the presence or absence of microorganisms that cause food infections (fecal coliforms and total coliforms) and to identify the presence of the Escherichia coli bacterium through laboratory analysis with subsequent dilutions and determination of the density of viable microorganisms present in the sample under analysis through NMP (Most Likely Number). Twelve samples were formed, divided into three groups of producers. Group A with 5 samples of coriander (Coriandrum sativum), group B with 5 samples of lettuce (Lactuca sativa) and group C with 2 samples of coriander. Biological samples showed a high level of contamination of total and fecal coliforms and presence of E. coli bacteria confirmed by biochemical tests in at least one dilution of the twelve samples analyzed during the months of March and June of 2017.
