Paleoparasitological investigations in these open-air sites are challenged by the severe taphonomic processes affecting parasite vestige preservation. Previous palaeogenetic work reported parasite helminth infection by\n                    <jats:italic>Ascaris<\/jats:italic>\n                    sp. in an individual from Jabuticabeira II (JABII)\n                    <jats:italic>sambaqui<\/jats:italic>\n                    , located in the Santa Catarina state, Brazil (2890\u00a0\u00b1\u00a055 to 1805\u00a0\u00b1\u00a065\u00a0years BP). To expand our knowledge about helminth infections in\n                    <jats:italic>sambaqui<\/jats:italic>\n                    people, this study applied a palaeogenomics approach in JABII. Sediments from pelvic and sacral regions of 3 JABII individuals and environmental samples underwent ancient DNA extraction and\n                    <jats:italic>cox<\/jats:italic>\n                    1 gene PCRs. High-throughput sequencing data were compared to a custom-built reference database. The JABII dataset revealed reads that are mapped against plathelminth and nematode parasites. Plathelminth observations are probably attributable\u00a0to pseudo-parasitism and are associated with the animal hosts identified within the JABII faunal assemblages. Two JABII individuals exhibited\n                    <jats:italic>Anisakis simplex, Contracaecum osculatum<\/jats:italic>\n                    , and\n                    <jats:italic>Ascaris<\/jats:italic>\n                    sp. Anisakids are common parasites of marine fish, crustaceans, and mammals that infect humans by consuming fish. Most of the fish identified at the JABII site are currently documented as being infected by Anisakidae.\n                    <jats:italic>Ascaris<\/jats:italic>\n                    sp. is verified in different JABII individuals from the previous study, confirming the spread of this soil-transmitted helminthiasis.
