This time of year, many people like to go to the beach vacation, seafood, aquatic naturally become indispensable food. However, a recent video showing the presence of parasites in seafood has been circulating on the Internet, which shows the presence of parasites in crayfish, fish, shellfish, crabs and other seafood, and demonstrates the separation process.

This, some of the "parasites" have the size of a thumb, can be wormed into the body of crayfish, some slightly thicker than a hair, exists in the body of the live fish, so people can not help but be alarmed, worried about the safety of seafood and other aquatic products. In this regard, the video calls on netizens to consume less seafood. How should we eat seafood healthy and safe? And how should we prevent parasites?

Zhang Shimin, a professor at the Department of Laboratory Medicine at Peking Union Medical College Hospital, said that most patients with parasitic infections have a **** the same characteristics in their diets, that is, they love to eat raw aquatic products, such as crayfish, sliced raw fish, raw beef, river crabs, and cold snails, etc., and that the main culprits that lead to parasitic diseases in them are these raw foods. To avoid parasitic infection, you also need to control your mouth first. Are parasites really that scary? According to reports, there is indeed a risk of parasites in seafood and other aquatic products, but this is a very common situation, as long as the scientific purchase, reasonable processing, consumers do not have to worry too much.

So how should we prevent parasites and eat seafood safely and healthily? Ruan Guangfeng, director of the Science and Technology Department of the Food and Nutrition Information Exchange Center of Science and Technology, said that we should pay attention to diet and water hygiene, do not eat raw and undercooked freshwater fish and shrimp, meat food, drink boiled water, improve personal and home hygiene, so as to wash hands before meals and after meals, etc., and at the same time, we should avoid bare hands and bare feet toiling in the farmland, vegetable fields. If you make your own sashimi at home, the fish you buy must first be fully frozen, parasites are afraid of rapid freezing. Also pay attention to standardized operation, raw and cooked separately to prevent cross-contamination.

In the end, heating and cooking is the most effective way to kill parasites. Soy sauce, wasabi paste and white wine are simply not enough to kill parasites in aquatic products and seafood, so don't be superstitious about their effects. In addition, the threat of seawater parasites is far less than freshwater parasites, freshwater aquatic food, semi-raw food risk is very high, do not pursue the taste of tender; wild than domesticated more likely to carry parasites, do not believe that pure natural; no matter what the parasites are afraid of heat, burned and boiled through is the protein, frozen can also kill parasites, need to be placed in the environment of minus 20 degrees Celsius for at least 24 hours; the handling of aquatic need to be separated from raw and cooked to avoid cross contamination; in addition to eating seafood is the most effective way to kill the parasites. In addition to eating seafood sashimi and other raw food, whether dipped in wine, vinegar, mustard, spicy oil, garlic sauce, etc., can not kill the parasites.
