most helpful answer yes you can get infected with certain types of ‘worms’ by eating raw or improperly cooked smoked marinated or salted fish. these worms can be found in herring mackerel north american salmon cod halibut rockfish sardines and squid. after eating improperly prepared fish these worms invade the intestinal wall or lining of the stomach. an infection in humans can cause stomach pain nausea and sometimes vomiting and diarrhea within a few hours of eating fish. freezing fish at -20°c (-4°f) for at least five days kills the ‘worm’ and makes sushi safe for eating.
