The main components of the parasite are protein and water, which will be denatured after cooking. After protein denaturation, the parasite has died, so the crayfish parasite can be boiled to death.

2 How long does lobster burn to kill parasites? Lobster burn 10 minutes can kill parasites.

The parasite will die if it is cooked to 10 minute at 70 degrees Celsius, and it will take shorter time to kill the parasite if it is cooked to 100 degrees Celsius. Although the boiling temperature of the water is 100℃, not all parts of the lobster are 100℃ when it is cooked, so it is better to cook the lobster for about 10 minutes.

3 Does the cooked crayfish have parasites? The cooked crayfish has no parasites.

The cooked crayfish has been added at high temperature, even if there are parasites in the live crayfish, there are no live parasites after cooking at high temperature, so as long as the cooked crayfish is not infected by parasites again, there will be no parasites.

Other methods to remove parasites include boiling and heating, and freezing.

The principle of killing parasites by freezing is the same as that of killing parasites by cooking. Both of them use physical reasons to denature protein and then inactivate it, which can also kill parasites.
