How are anisakidae larvae killed?

Explanation:
Parasites in fish are controlled by either very cold treatment or by sufficiently high heat. Freezing can inactivate or kill larvae, and heating the fish to a safe internal temperature for a short period also destroys them. Simple refrigeration doesn’t reliably kill anisakids, and UV exposure doesn’t penetrate fish flesh to inactivate them. The option that combines a thorough cold step with a proper heat step reflects the two proven ways to ensure the parasites are eliminated, making it the best choice. Other methods listed don’t provide reliable parasite destruction because they don’t reach or sustain conditions needed to kill larvae embedded in tissue.
