[Intestinal parasites in the vendors and consumers of street food. A study conducted in the Dakar area].
In order to assess the parasitic risk for street-food consumers, the authors conducted two studies from September to August 1996, one on street-food sellers (305) and the other on consumers (235). Among the consumers, 127 were considered as not exposed to risk, since they did not frequent the sector being surveyed, and 108 were exposed because they consumed at least one meal per day cooked by the sellers of this area. Both groups filled out a questionnaire and had their stools analysed according to the RITCHIE method. The infection rate was 60% among sellers and 45.5% among consumers. Protozoans were predominant in both groups. Among the consumers, those exposed were significantly more infected. Even though the sellers represent a parasitic risk due to their level of infection and the typology of parasites they shelter, one cannot assume that consumers are contaminated only by the sellers of street food. However, appropriate measures must be implemented in order to minimize risks for street-food consumers.
