First, mussels have parasites.
Obviously, mussels have delicious meat and high nutritional value, but there are parasites in mussels, which everyone must know, but it is not because they are parasites that they cannot be eaten. When mussels are eaten, high-temperature disinfection can kill parasites. Before eating, blanching with 100 degree boiling water can burn the parasites inside.
Second, the precautions for eating mussels
If you want to eat a box lunch, you must pay attention. Don't choose dead things when you buy them, that is to say, you can't eat them, because the dead meat will rot and some bacteria will multiply, so eating this dead mussel is more likely to cause food poisoning and so on, and even cause gastrointestinal problems, indigestion, vomiting and diarrhea. Another point is that mussels must be thoroughly cleaned before cooking. Mussels live in mud houses, so they are dirty, especially in their intestines. Therefore, before cooking, the intestines of mussels must be cut open and the contents thoroughly cleaned.
In short, there will be parasites in mussels, which can't be eaten raw or directly without being cooked. You must cook it thoroughly before eating it, which has no effect on your health.
