Crayfish has been exposed in many news reports, saying that it contains parasites, and if it is not eaten well, it may be infected with parasites. Therefore, eating crayfish will infect parasites, and it is not without certain possibility. Because crayfish are cultured in fresh water, there are many kinds of parasites in the water. Crawfish grow in this environment for a long time and naturally have parasites in their bodies.
In general, as long as the cooking method is correct, there is no problem. If it is difficult to kill parasites due to improper cooking, eating too much may lead to the risk of contracting parasites. This kind of news is often reported by the media. It is true that some people eat crayfish and are infected with parasites and sent to hospital for treatment.
Like us, we usually buy more crayfish outside, whether it is restaurants, food stalls or night markets. Many businesses, driven by interests, may not do well enough, or buy dead shrimp for profit when they purchase goods. In both cases, if you eat too much, the risk of infection with parasites is particularly high. So try not to eat crayfish outside, or buy them and cook them yourself.
Before cooking, clean the crayfish, brush it repeatedly with a toothbrush, and remove the shrimp line from beginning to end. Then put more seasoning to deodorize and sterilize, and open the fire for a long time, which will help kill parasites. Crayfish must be cooked at high temperature, otherwise it will be infected with parasites.
