GUILHERME, Ana Lucia Falavigna et al. Prevalence of intestinal parasites in horticulturists and vegetables from Feira do Produtor de Maringá, Paraná, Brazil. Rev. Soc. Bras. Med. Trop. [online]. 1999, vol.32, n.4, pp.405-411. ISSN 0037-8682. http://dx.doi.org/10.1590/S0037-86821999000400012.
Few studies have assessed the contamination of vegetables at Brazilian production sites. From April 1996 to December of 1997, the sanitary conditions of raw consumed vegetables sold in the Feira do Produtor de Maringá were investigated. We based the analyses on the contamination of vegetables, of the producers (stool samples and material under the fingernails) and of the water used for irrigation. It was observed that 16.6% of 144 samples of five different types of vegetables were contaminated with intestinal parasites. Forty three of 163 individuals (26%) were infected with one or more parasites. Only three of the 49 samples of material under the fingernails analyzed were positive for intestinal parasites. Analysis of samples of the water used for vegetable irrigation showed that the water did not satisfy bacteriological standards of potability. We conclude that in the investigated area the contamination of vegetables occurred during the production phase and that a sanitary education campaign directed at the producers is needed.
