According to reports, the newly released "Standard" stipulates the terms and definitions, requirements, test methods, inspection rules, labeling, marking, packaging, transportation and storage of raw salmon, and applies to raw salmon products that can be directly consumed by processing with fresh or frozen salmon as raw materials.

The Standard clearly states that salmon is a collective term for salmonids, including Atlantic salmon, rainbow trout, silver salmon, king salmon, sockeye salmon, fall salmon, pink salmon and so on.

So should rainbow trout be classified as salmon?

In the opinion of Chen Shunsheng, a professor at Shanghai Ocean University, the move is not appropriate. Chen said the rainbow trout and salmon are not the same kind of fish, rainbow trout is a freshwater fish, the form and the Pacific salmon close. The two are related, but rainbow trout is not salmon. "The conventional Chinese term for salmon is mainly Atlantic salmon."

"Salmon is a common name, not a scientific name. We're now expanding the criteria all of a sudden. The scientific name can be published, but the publication of the common name is not something that one person can publish; it can only be published after the public accepts you." ? Chen Shunsheng said.

Sina microblogging authentication as "well-known commentator, essay writer" Qiao Zhifeng pointed out: "rainbow trout is rainbow trout, salmon is salmon, why the emergence of the two claims? In fact, the rainbow trout is rubbing the IP of salmon, because salmon is more famous, the market price is much more expensive than rainbow trout."

For the price difference between the two, Chen Wei, owner of a Japanese restaurant in Hangzhou, was quoted by the media as saying that the price difference between the two can be nearly double at times. Chen Wei has cited the wholesale market in Hangzhou at a certain time imported salmon a catty wholesale price of about 55 yuan, rainbow trout is the price of 30-40 yuan.

It is worth mentioning that although rainbow trout and salmon are very different in appearance, they are very close after being made into sashimi. According to industry insiders, as long as it is fresh enough to be made into sashimi, it is difficult for the average person to distinguish the difference between them with the naked eye.

And in the view of Cui He, president of the China Aquatic Products Distribution and Processing Association, calling rainbow trout salmon may be the rainbow trout borrowing the light of the Atlantic salmon, but perhaps within a few years, it is the Atlantic salmon borrowing the light of the rainbow trout. "Because the price of rainbow trout in a few more years will certainly be the same as abroad, and the people will realize that the rainbow trout meat is beautiful, brightly colored, and all kinds of indicators are higher than the Atlantic salmon."

In fact, it is mentioned in the Standard that the relevant products should be labeled with the origin of the raw fish as well as the species name, and examples of species name signs are given: salmon (Atlantic salmon), salmon (rainbow trout).

The media in a well-known domestic e-commerce platform to see, has been labeled salmon (rainbow trout) fresh products on the line and higher prices. One of the products labeled as salmon (rainbow trout) middle 300g is priced at 89 yuan, and 52 copies have been sold. On the same platform, some products labeled as Norwegian salmon were sold at prices even lower than that.

What is the group standard?

It is worth mentioning that the release of the "standard" belongs to the group standard, and this has become the object of questioning by many netizens.

According to the Standardization Law of the People's Republic of China*** and the State of China, which came into force on January 1, 2018, standards include national standards, industry standards, local standards, and group standards and enterprise standards. National standards are divided into mandatory standards and recommended standards, and industry standards and local standards are recommended standards.

The state encourages societies, associations, chambers of commerce, federations, industrial and technological alliances and other social groups to coordinate the relevant market players *** with the development of group standards to meet the needs of the market and innovation, the members of the group agreed to be adopted by the group or in accordance with the provisions of the group for voluntary adoption by the community.

It is understood that the "standard" by the China Aquatic Products Circulation and Processing Association in conjunction with the salmon branch member units of the Qinghai Minze Longyangxia ecological water breeding Limited, Shanghai Heyu Frozen Food Co. Among them, the China Aquatic Products Distribution and Processing Association is a non-profit community organization with independent legal personality.

In other words, the "standard" will be adopted by the members of the above groups within the agreement, the social aspects can be adopted voluntarily. And once adopted by enterprises, it will be mandatory for their products.

It is worth mentioning that, according to the standardization law, the technical requirements of the recommended national standards, industry standards, local standards, group standards and enterprise standards shall not be lower than the relevant technical requirements of the mandatory national standards. And food safety standards are mandatory. Therefore, the group standard must be consistent with or higher than the relevant national standards.

According to Cui and introduction, the "standard" for the current aquatic products in China's human health hazards of parasites - nematodes, trematodes and tapeworms, combined with the life history of parasites, with reference to the "national standard for food safety, animal aquatic products (GB10136-2015)" in the ready-to-eat aquatic products in the parasitic worm Requirements for the three parasites infecting the human body stage (trematode cysts, nematode larvae and tapeworm schizothoracin) are limited to require not to be detected, to protect the safety of consumer consumption.

Cui and at the same time, said the raw food standards actually determine the salmon, whether imported or domestically produced, to microbial, parasites and other indicators to determine whether it can be eaten.

However, for the Standard, raw materials that do not have risk control measures for parasites at source should be frozen in any of the following ways to kill parasites: first, continuously frozen below -20°C for 24 hours; second, continuously frozen below -35°C for 15 hours.

Chen Sun-sheng said the above method is a way to eliminate parasites from seawater salmon, "It's OK for Atlantic salmon, but I don't think there's a good basis for treating freshwater rainbow trout." In Chen Shunsheng's opinion, the above method is not necessarily effective for the elimination of liver fluke and lung fluke.

Can freshwater fish be eaten raw?

In fact, behind the controversy over whether rainbow trout belongs to salmon, the food safety issue of whether it can be eaten raw is what many netizens are most concerned about.

Just in May this year, the Chinese Academy of Fisheries Research, Heilongjiang Fisheries Research Institute Wang Bingqian said in an interview with the media, salmon has no parasites does not depend on the growth of seawater or freshwater, but to see whether the growth process is safe and controllable.

In Wang Bingqian's view, both seawater and freshwater can be eaten raw, provided that there is no chance of pathogen infection or no pathogens in the breeding process, and there is a freezing process before eating.

"We are eating fish meat, not skin, and the freezing process will kill the surface parasites directly. The rainbow trout or any other salmonid fish that is farmed in this country now is artificially fit. Artificial fit in all through the autoclave sterilization process, so the so-called parasites generally do not appear in the dietary link." Wang Bingqian said.

I just want to eat fish well
