Parasites of salmon and raw crabs: Salmon has parasites. Salmon is a seafood food, which not only contains parasites, but also may carry viruses. Therefore, when eating it, we must pay attention to hygiene conditions, and it is best to cook it at high temperature, which can effectively kill viruses and parasites. Don't eat salmon raw often.

Many people will check the meat quality of crabs first when eating crabs, such as the meat quality of crabs is pink, or the meat quality of crabs is no longer Q-shaped, which has great influence. In fact, when eating crabs, we should first pay attention to the method of eating crabs. We can choose to eat them after heating or raw, but when eating crabs, we find that there are some white filaments on the meat, which many people worry is parasites.

White transparent filaments are not necessarily parasites. There are parasites in crabs. It is best to cook crabs at high temperature. The reason is very simple. As parasitic creatures, parasites absorb nutrients in the host and survive. Parasites adapt to the temperature of the host, and through high temperature, they can kill parasites in crabs.

The larvae of Paragonimus are mainly present in crabs. Paragonimus westermani and crab are the second intermediate hosts of Paragonimus westermani larvae.

And the transparent filament you mentioned, I don't know if it is a parasite, if it is, it is estimated to be a kind of nematode and tapeworm. Again, the parasites in crabs are mainly paragonimiasis.
