contracted from sushi or lightly marinated,
salted, or cold-smoked preparations. Farmed
salmon are much less likely to be infected
than wild salmon.
Tapeworms and Flukes Larvae of the
tapeworm Diphyllobothrium latum, which can
grow in the human intestine to as long as 27
feet/9 meters, are found in freshwater fish of
temperate regions worldwide. Notable among
these is the whitefish, which caused many
infections when home cooks made the
traditional Jewish dish gefilte fish and tasted
the raw mix to correct the seasoning.
More serious hazards are a number of
flukes, or flatworms, which are carried by
fresh- and brackish-water crayfish, crabs, and
fish. They damage the human liver and lungs
after being consumed in such live Asian
delicacies as “jumping salad” and “drunken
crabs.”
