Determinación de enteroparásitos en frutas, verduras y hortalizas como vehículo de infecciones en Pungal Grande y San Pedro, Guano.

Foodborne diseases are a major global health problem, including parasitic infections, caused mainly by fecal contamination of agricultural products. The objective of the present work was to determine the enteroparasites present in fruits and vegetables and their role as a vehicle of transmission, in the communities of Pungal Grande and San Pedro. The study employed a quantitative, non-experimental - transversal, descriptive methodology. We collected 773 samples, 310 fruits, 188 vegetables, and 275 vegetables from crops in the area. Three diagnostic techniques were used for the analysis: Direct Examination, Ritchie and Ziehl - Neelsen. Positivity was 74.51%, with 576 parasitized samples, most of them with 555/320 protozoa (71.80%) (χ2 26.113 P<0.0001), in contrast with helminths 131/773 (16.95%) (χ2=33.980 P<0.0001) The anthropozoonotic species detected were Blastocystis (57.19%), Entamoeba (15.66%), Cryptosporidium (7.65), Cyclospora cayatenis (6.56), Balantidium coli (3.64%), Cystoisoporo belli (0.73), Giardia (0.55%). Vegetables were more frequently parasitized 86.55%, than fruits 67.1% and vegetables 69.15% (χ2=32,743 p<0.0001). Among the risk factors for contamination of these vegetables, we consider irrigation of crops with water conducted through open channels, contamination by direct defecation or by fertilizer with animal excreta and inadequate sanitary conditions. To control parasitic transmission, health education is essential to make the population aware of the importance of hygiene in the handling of agricultural products.
