Abstract Soil samples collected near municipal schools (public/EMEI and private/EPEI schools), clubs (CLB), public squares (PS) and residential condominiums (CND) and samples of animal faeces from the Zoonosis Control Centre (CCZ) of the municipality of Votuporanga/SP were analysed using the Baermann method for the detection of zoonotic helminth larvae. The prevalence rates of the nematode genera identified were determined, and the results were compared using Fisher’s exact and chi-square frequency tests. Information about cases of larvae migrans in the population were collected from the Family Health Units and the private health plans. All sites were positive for Ancylostoma spp. and, with the exception of EPEIs and dog faeces, for Strongyloides spp. The prevalence of Ancylostoma spp. was 87.5% for CND samples, 74.29% for EMIEs, 63.64% for CLB, 61.76% for PS and 64.29% for dog’s and 42.86% for cats at CCZ. The prevalence of Strongyloides spp. ranged from 14.29% (cats/CCZ) to 41.18% (PS). Cases of cutaneous larva migrans were reported during interviews. Thus, from the public health perspective, the risk of individuals that frequent recreational areas in the municipality, especially children, to be infected by helminth larvae is noteworthy, indicating the need to develop policies aimed at controlling this important zoonosis.
