Its adults are known worldwide, but its larvae have been reported in fish only from Peru, where most human cases have been reported. In the Argentine sea, sea lions host this species, which allow infer that previous records of pseudophyllidean larvae in Argentine hakes, Merluccius hubbsi, belong to this species. Aim: To identify plerocercoids parasitizing hakes and, from a pubic halth perspective, to assess the risk of parasitism for consumers.Methods: A total of 471 hakes caught in 11 samples in the southern Patagonian waters were measured, headed and gutted (H&G) and examined for plerocercoids. H&G fish were washed and parasites were retained in a sieve. Then, each fish was filleted and examined by transillumination. Larvae were characterized by sequencing the partial lsrDNA (D1D3 domains) and almost complete cox1.Results: Larvae were recovered from H&G fish in 5 samples at prevalence
