Is there a security system that can be identified by the eye?

Yes. It's often shown in movies.

Personally, I don't think I can afford to use this stuff at home.

There are many parasites in wild salmon, with Anisakis being the most common. However, marine parasites cannot survive in the human body for a long time, so they mainly cause abdominal pain and diarrhea, and only in rare cases there is a perforation of the digestive tract.

In contrast, farmed salmon may have fewer parasites, mainly due to the use of fishery medicines. Freshwater farmed rainbow trout are also sometimes used for sashimi, but the risk is greater than that of salmon because the parasites in freshwater fish can survive in the human body, the most common of which are liver flukes. If you are worried about parasites, you can freeze the fish at -20 degrees for at least 1 day, and the parasites can freeze to death.

The thiaminase in seafood can destroy vitamin B1 in food when eaten raw, and in addition, moderate heating will not only not destroy the protein and unsaturated fatty acids in salmon, but is more conducive to the digestion and absorption of protein. Eating salmon raw will inevitably have bacteria and parasites, and eating salmon raw is not the best solution. Any fish should be cooked and eaten cooked.

Disadvantage: Risk of parasite infection.

The main parasite that salmon meat may be infected with is called Anisakis elegans, also known as sea beast stomach nematode, which belongs to the nematode class Ascaris Allisakiaceae among parasites.

According to the research of the quarantine and disease control department, the infection rate of Anisakis in China's imported and exported marine fish is about half, and some fish species even reach 100%. Anisakis is a relatively common parasite with larvae about 1 cm to 3 cm long.

It will survive in the digestive tract in the form of larvae, when it travels around in the digestive tract, it may burrow into the biliary tract or the folds of the digestive tract wall and induce acute inflammatory reactions, once infected, the parasite may lead to inflammation of the gastric mucosa, edema, and even bleeding and allergic reactions, etc., damaging the gastrointestinal tract, causing diarrhea, vomiting, etc., which may lead to life-threatening in severe cases.

There are some people who like to eat raw animals'Healing'or'Health care'。'Raw loach**'Putting a large number of people in the hospital did not make people think about these fundamentally'Alternative**'The risks and benefits of simply thinking that the victim was unlucky and ran into it'Bad loaches'。For the sake of delicacy or illusory'Health care', there are many people who eat frogs raw, eat snake gall bladder raw, and drink snake blood raw.

Recently, a lump formed by parasites was found in the chest of a lady in Guangdong, which once again aroused people's attention'Eat raw'attention. There are risks associated with eating these things, so is it dangerous to eat salmon raw, which is popular all over the world?

The safety risks of salmon and other fish mainly come from parasites and disease-causing bacteria, and salmon contains a lot of parasites, so you must be cautious when eating, and do not eat again for your own health and safety.

Salmon can be infected with a variety of parasites, the most common is Anisakis worm, if the amount eaten at one time is relatively large, it will produce acute food poisoning; Even eating small amounts can lead to future allergies to nematodes.

Obviously, the U.S. guidelines can kill nematodes more fully than the EU requirements, but they are more difficult to operate. The EU requirement is easier to achieve, and some experiments with nematode survival and storage temperature times have shown that this requirement can also be quite safe. There are no regulations in Japan, and there are many people who prefer raw food, so there are far more cases of parasites in Japan than in Europe and the United States.

1. Salmon is rich in unsaturated fatty acids, which can effectively reduce blood lipids and blood cholesterol, prevent and treat cardiovascular diseases, and two meals a week can reduce the probability of death from heart disease by one-third. Salmon also contains a substance called astaxanthin, which is a very powerful antioxidant. The -3 fatty acids contained in it are essential substances for the brain, retina and nervous system, which can enhance brain function, prevent Alzheimer's disease and prevent vision loss.

2. Salmon can effectively prevent the occurrence and development of chronic diseases such as diabetes, has high nutritional value, and enjoys the reputation of "treasure in water".

Precautions. 1. Suitable for people: cardiovascular disease, anemia, cold patients, thin people.

2. Unsuitable people: patients with allergies, gout and hypertension.

3. Purchase: Fresh salmon has a layer of intact and bright silver scales, which are translucent and shiny. The skin of the fish is black and white, and there are no bruises.

The eyes are clear, and the pupils are dark and shiny. The gills are bright red in color and have red mucus in the gills. The flesh of the fish is a vivid orange-red color.

4. Don't buy: Gently press the salmon with your fingers, the fish meat is not firm, and the salmon that cannot be restored to its original state immediately after pressing it down is a sign that it is not fresh.

5. Cooking: Just make the fish eight mature, which not only preserves the freshness of the salmon, but also removes the fishy smell.

6. Don't cook: Salmon doesn't need to be particularly bad.

7. Suitable for eating: It is best to eat cooked marine fish, and raw food will cause severe abdominal pain and allergies due to Anisakis infection.

8. Don't eat: Pregnant women should avoid eating raw salmon.

9. Storage: Cut fresh salmon into small pieces, seal it with plastic wrap, and then put it in the freezer, if it is -20 quick-frozen, it can be stored for 1 2 months, and -10 The storage time is short, and it should be eaten as soon as possible.

Salmon is nutritious and delicious, but don't eat it raw just yet.

Raw salmon has bugs that are invisible to the naked eye!

Many people have the habit of eating salmon raw, but at yesterday's food safety briefing, the Municipal Food Office and the Beijing Entry-Exit Inspection and Quarantine Bureau issued an early warning to the public: There are certain safety risks in eating raw salmon.

According to the person in charge of the Food Supervision and Inspection Department of the Entry-Exit Quarantine Bureau, the salmon mainly comes from Northern Europe, Australia and other places, and last month the bureau seized a batch of 135 pieces of 2,691 kilograms of salmon at the airport port, which tested positive for Listeria monocytogenes. It is a zoonotic pathogen that manifests primarily as sepsis, meningitis, and mononucleosis after infection, and can still thrive in 4 environments. The bacteria are more tolerant to heat and can only be killed when the processing center temperature is above 70 for 2 minutes.

In addition, even if the port inspection is passed, there is a possibility that it can breed germs when it is refrigerated in the supermarket or at home.

Therefore, the Food Office reminds consumers to pay attention to the heating of salmon before consumption and consume it as soon as possible. Whether the Chinese label meets the national mandatory standards is an important indicator to distinguish the authenticity of salmon.
