ABSTRACT
Objective:
The present study aimed to evaluate the presence of helminthes and intestinal protozoa in vegetables commercialized in Diamantina, a municipality located at Jequitinhonha Valley, one of the poorest regions of the world.
Methods:
A total of 108 specimens, including lettuce, green onion and rocket, were monthly collected from the most popular open street market, green grocery and supermarket of the municipality. The samples were processed by a concentration method and evaluated by light microscopy for parasitological identification.
Results:
The percentage of contamination was 50.9% (55/108), with predominance of nematode larvae (36.5%), cysts of Entamoeba coli (26.0%) and eggs of hookworms/Strongyloides spp. (12.9%). Lettuce showed greater contamination rate (61.1%) and samples from the open street market were more contaminated (77.8%). Information collected at each point of sale pointed the field cultivation as the critical step for such contaminations.
Conclusion:
Vegetables marketed in Diamantina presents a wide variety of intestinal parasites, which may represent a potential risk to the health of consumers of fresh vegetables.
