Anisakis, a parasite found in fish and cephalopods, has caused health problems for many people, especially as the consumption of raw fish has increased in Spain. Besides digestive problems, fever, and other symptoms, anisakis has another consequence, though not as serious: the need to freeze the fish to ensure the parasite is killed. This obviously affects the taste and texture of the fish. But a new machine could eliminate this parasite as a problem. At the Madrid Fusión congress, a prototype, invented by the University of Zaragoza, was presented that kills anisakis without the need to freeze the fish, allowing it to be eaten with all its properties intact.
