The Japanese Broad Tapeworm is the largest worm known in wild salmon and can grow up to 30 feet long in the human body, per the Centers for Disease Control (CDC). Eating raw fish like sashimi or sushi is associated with tapeworm infection.
Imagine seeing something hanging out of your butt when on the toilet, and you think it’s your insides…but no, it’s alive and wiggling!
That is what has happened to a few, but thankfully it only happens rarely. But you just never know, so check where your salmon and sushi is coming from, how fresh it is, and if it has been frozen.
5. Raw Fish
Consuming uncooked salmon, either in sushi or smoked, is the main source of tapeworms. At first, scientists thought the parasite was only common in Asian countries, but the CDC found it has shown up in North American fisheries and in Alaskan wild salmon. Tapeworms have also been found in freshwater fish of trout, perch, and pike.
4. Tapeworm Life Cycle
The tapeworms start out when the eggs of infected animals or humans are transported from feces into water. Then crustaceans like shrimp ingest these larvae or eggs, which are then consumed by bigger fish. Then when a human eats a piece of raw or undercooked fish like salmon, it attaches to the walls of your intestines.
