【 摘 要 】

Water and raw vegetables consumed in ten nursery schools were evaluated for the presence of transmissible forms of enteroparasites. The water was submitted to filtration through membranes. The washed membrane water was submitted to the Faust method. The in natura and washed vegetables were washed and the water analyzed by the sedimentation method. Contamination was not detected in one school; in two schools, all the materials were contaminated; in four schools, two items were contaminated and in three, one material presented contamination. The water presented a contamination index of 0.7% contamination (Hymenolepis diminuta, Strongyloides stercoralis and Ancylostomatidae); the vegetables in natura, 3.9% (Strongyloides stercoralis, Ancylostomatidae, Ascaris lumbricoides and Giardia lamblia) and the washed samples 1.3% (Strongyloides stercoralis, Ascaris lumbricoides and Giardia lamblia). The water and vegetables are enteroparasites vehicles. The larval form predominated. The vegetables in natura presented higher contamination than those that were washed. Elimination of these forms in vegetables was not guaranteed by washing.
