Salmon can be eaten raw? Salmon is rich nutrition value is a kind of fish, and its sweet-meated, care also has a good effect to the body, but must pay attention to how to eat it, because a lot of people like to eat raw salmon, actually it's so easy to cause the bacterium salmon, cause harm to your health.

Some people like to eat raw animal to "cure" or "care". 's "health" godmother Ma Yueling loach therapy "eat a lot of people in the hospital, also does not make people went up from the fundamental thinking these" alternative "of risk and benefit, just simply think that the victim of bad luck, met bad" loach ". In order to taste or unreal "care", raw frogs, raw snake gall, drink blood. Recently guangdong a woman chest found parasites form lumps, cause people concerned about the "raw" again. Eating these risks, so popular in the world of salmon, raw will there be dangerous?

The security risks of salmon and other fish mainly from four aspects: heavy metal pollution, biological toxin, parasites and pathogenic bacteria.

Heavy metal pollution is decided by the growth of the fish water quality and biological toxin produced by some algae and fungi in the water. They is determined by the source of the fish, the effects of a subsequent processing, raw cooked there would be no much difference. So, avoid the risk of these two aspects, only through the fish to ensure regular source.

There are many types of salmon may be infected with parasites, the most common is pointed nematodes. If you keep eating a quantity is larger, can produce acute food poisoning; Even eat less, can also cause human body allergic to nematodes in the future.

As in the cold water in the growth of parasites, pointed nematodes is not difficult to kill. In under 60 degrees, for example, they will be. But for people like to eat raw, heated to this temperature are unacceptable, can only through the low temperature freezing them. As higher than bacteria some animals, they really can freeze to death, just need a slightly harsh conditions of some. Eu rules, the fish must be less than 20 degrees below zero storage more than 24 hours, can be used for raw food. They think that such treatment can be sufficient to kill the parasites. The United States is not mandatory, only recommended "operation manual". The recommended far more stringent than the requirements of the European Union, is minus 20 degrees more than 7 days, or more than 15 hours to 35 degrees below zero.

Obviously, compared with the requirements of the European Union, America's guide to kill nematodes can more fully, but its operation difficulty is big. The eu requirement for easier to implement, and some of the nematode survival time and storage temperature experiments showed that this requirement also can obtain very high security. Japan is not the rule, and like a raw food much, so the Japanese to eat raw fish parasite infection cases is far more than Europe and the United States.

Some people have too the freezing process can destroy the fish flavor taste, like the raw fish "fresh". Without heating, do not freeze again, can only rely on the naked eye to identify parasite and manually remove. Fortunately, is much bigger than bacteria, parasites by naked eye. If cut the meat thin, very carefully check, it is also possible in addition to the. , however, is whether the "security", but also depends on how many fish itself parasites, and check whether the removal is complete. It's a little rely on luck.

Above is eat salmon, you need to know the healthy eating common knowledge problem, only we eat healthy, then can better access to the food of nutritional value, so you have to understand these problems, it can help us, from the impact of some diseases.
