“…Metacercariae isolated from M. liza and incubated in mullet muscle tissue at different temperatures showed that all metacercariae were dead after heating for 15 min at 60˚C, 100˚C and 180˚C. When frozen, all metacercariae died after 2 hr of exposure to −35˚C and −20˚C, but 24 hr of exposure to −10˚C was necessary to kill all metacercariae in the fillets [95]. The specific procedures for inactivation of parasites was important to prevent outbreaks of trematodiases caused by A. longa.…”

“…Although heterophyid species are already included in the List of Risk Classification of Biological Agents by the Brazilian Health Ministry [ 92 ], human cases are no longer reported. Studies on the viability of heterophyid metacercariae of A. longa have been perfomed [ 93 , 94 ] with methodological standardization performed by Borges et al [ 95 ]. Metacercariae isolated from M. liza and incubated in mullet muscle tissue at different temperatures showed that all metacercariae were dead after heating for 15 min at 60˚C, 100˚C and 180˚C.…”

Fish-borne heterophyid trematodes are known to have a zoonotic potential, since at least 30 species are able to infect humans worldwide, with a global infection of around 7 million people. In this paper, a ‘state-of-the-art’ review of the South American heterophyid species is provided, including classical and molecular taxonomy, parasite ecology, host-parasite interaction studies and a list of species and their hosts. There is still a lack of information on human infections in South America with undetected or unreported infections probably due to the information shortage and little attention by physicians to these small intestinal flukes. Molecular tools for specific diagnoses of South American heterophyid species are still to be defined. Additional new sequences of Pygidiopsis macrostomum, Ascocotyle pindoramensis and Ascocotyle longa from Brazil are also provided.
