Evaluation of intestinal parasites present in vegetables sold in the city of imperatriz, maranhão, Brazil

Worldwide, diarrheal diseases caused by helminths and protozoa represent a public health problem. Despite the benefits that vegetables and fruits have as non-pharmacological prophylaxis against diseases, they are also sources of transmission of pathogens of fecal origin. The carelessness in planting and handling vegetables brings harm to human health if there is not adequate hygiene. Thus, the study aimed to analyze the presence of helminths and protozoa in leafy vegetables lettuce (Lactucasativa) and cauliflower (Brassica oleracea) sold in supermarkets and street markets in the city of Imperatriz, Maranhão, Brazil. A total of 30 samples were analyzed by the sedimentation method, all of which were collected in different months and at the same locations. Thus, the most common parasites in cauliflower and lettuce leaves were Balantidium coli, Strongyloidesstercoralis and Ascarislumbricoides. In addition, it was highlighted that all 30 samples were positive, and parasites such as Hymenolepisdiminuta, Trichuristrichiura, Enterobiusvermicularis, Entamoebahistolystica and Giardialamblia were also found. Based on the study, it is suggested that direct actions by specific government agencies are necessary for education and sanitary inspection, as errors in the production and commercialization of these foods represent a risk to the population.
