Freezing fish to an internal temperature of -4 degrees Fahrenheit for at least seven days will kill parasites. Cooking seafood to an internal temperature of at least 145 degrees Fahrenheit for 15 seconds also kills parasites, the CDC says.
Can fish parasites be killed by cooking?
Most of these parasites cause mild to moderate illness such as nausea, vomiting, diarrhea, and abdominal pain, but more serious problems such as central nervous system and organ damage can occur. These parasites are usually killed by cooking the fish to a temperature of at least 145°F for fifteen seconds.

Cooking at core temperature 60–75 °C for 15–30 min inactivates parasites in most matrices. Freezing at −21 °C for 1–7 days generally inactivates parasites in FoAO, but cannot be relied upon in home situations. Parasitic stages are sensitive to 2–5% NaCl, often augmented by lowering pH.
Can tapeworms survive cooking?

Can you get worms from fish?
When humans eat raw or undercooked infected fish or squid, they ingest nematode larvae. Once inside the human body, the larvae can invade the gastrointestinal tract. Eventually, the parasite dies and produces an inflamed mass in the esophagus, stomach, or intestine.
Will cooking fish remove bacteria?
Avoid Cross-Contamination
Even though cooking will destroy most of the harmful micro-organisms that may be on fish, cooked products (and any other foods) can be re- contaminated through poor handling or storage practices.
