Fish have parasites. If the parasites have been killed after the fish has been cooked at high temperature, the fish can generally be eaten; if they have not been killed, the fish cannot generally be eaten. 1. Can be eaten: If the fish has been cooked at high temperature, the parasites on the fish have been killed and generally can be eaten. Although there are still parasites on the fish at this time, but after the high temperature kill, generally will not have a serious impact on the body, and its body nutrients still exist, but also for the body to supplement nutrition. 2. Can not eat: If the fish after high-temperature cooking, the body of the parasite still exists, usually recommended not to eat, or may be infected with parasites, leading to nausea, vomiting, diarrhea and other symptoms. It can be seen that fish with parasites can be eaten, depending on whether the parasites are killed after high-temperature cooking before deciding. River food and seafood, including fish, have a higher chance of carrying parasites, so don’t eat them raw and cook them according to the correct cooking method before eating.
