I read in "Eléments de parasitologie médicale" that

 *humans are infested when they eat *predator* fish, mainly [brochet,
perche, lotte d'eau douce] (sorry, no French/English dictionary)

 *The symptoms can be mild. 88% of the Canadian Eskimos, and 25 to 100% of
the Finns (depending on districts) are infested by that tapeworm.

 *Niclosamid (sp?) = Tredemine (TM) is very efficient against the parasite.

Best wishes,
