Qualidade higiênico-sanitária de alface comercializada em Dourados - MS

Abstract

The vegetables may contain protozoan cysts, helminth eggs and larvae serving as a viable route of transmission for intestinal parasites especially when eaten raw, due to the potential health risk. Among the striking consequences of triggering intestinal parasites are diarrhea, anemia, bleeding, nutritional imbalances and in some rare cases leading to death. Based on these aspects and considering, especially the lack of information in Dourados-MS tried to analyze qualitatively and quantitatively the presence of parasites, which can be transmitted through oral ingestion of lettuce sold in the supermarket aisle of the city. We evaluated two methodological techniques (flotation and sedimentation spontaneous) and two varieties of lettuce (curly and flat), in which there was the presence of the main genres of intestinal parasites that can cause infection in man. So, this way the sanitary conditions of such fresh vegetables could be evaluated. We found eggs of genres: Ancylostomideos, Ascaris sp. Balantidium sp. Diphyllobothirum sp. Enterobius sp. Hymenolepis sp. Paragonymus sp. Shistosoma sp. Taenia sp. and Trichuris sp. The technique of spontaneous sedimentation extracted most eggs of parasites compared with the flotation.
