Parasitological examinations were performed in material derived from 220 vegetables to detect cysts and eggs of intestinal parasites. This material was collected from supermarkets in northern and southern areas and from CEASA (Central Supply Market--40 vegetables) in Rio de Janeiro city. Vegetables proceeding from the northern areas presented a greater degree of contamination mostly of helminth eggs; lettuce was the most contaminated vegetable. The authors suggest that differences found between the northern and southern areas of the city may be due to either packing or manipulation by shop assistants and consumers.
