Eat the fish before it is cooked. Eating undercooked fish may lead to parasitic infection. When cooking fish at home, please make sure that the fish is easy to peel, the meat is fresh and tender, and the meat has no translucent signs. Don't put uncooked fish with other foods to avoid cross-contamination.
4. Don't eat fish with high mercury content. Most fish are slightly polluted by mercury, and most healthy adults have no problem decomposing trace mercury. But pregnant women or lactating women and children should avoid eating some fish and shellfish to reduce the harm of mercury poisoning.
Larger fish have the highest mercury content, such as sharks, swordfish, mackerel and square head fish. For most people, it is best to try to avoid eating these fish. You can choose to replace them with other fish and shellfish with lower mercury content, such as shrimp, cod, canned tuna, salmon and catfish.
