This study was conducted to evaluate the contamination for parasites in the frog Telmatobius jelskii, used in the preparation of extracts intended for direct human consumption in the form of beverages expended in public areas. Frogs (n=84) were taken in 21 food carts in Lime city center. Direct coproparasitological techniques and the Travassos technique were used for the detection of gastrointestinal parasites. For the detection of metazoan parasites the small and large intestine, liver, lung and bladder were revised. All frogs had parasites of at least three species, identifying the presence of two digenea: Gorgoderina attenuata (7.2%) and Gorgoderina sp (11.9%), two nematodes: Hedruris heyeri (100%) and Capillaria sp (6.0%) and two zoonotic protozoa: Cryptosporidium sp (100%) and Balantidium sp (100%). The results showed high contamination with parasites in frogs that are used in the preparation of extracts, which implies a risk of infection for consumers if considering that extracts were prepared with whole frogs that are not are not subjected to cooking processes.
