Resumen:
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.
