Why is it stamped on pork?

On December 1, 2021, WeChat***Nanchang Market Supervision, which is certified as "Nanchang Market Supervision Administration", published an article "Round Chapter, Square Chapter?".Do you know the chapter on the pork?It explains in detail why the raw pork in the market must be stamped, as well as the material composition of the pork stamp. According to the article, "in the market circulation, each batch of raw pork must have 'two certificates and two chapters' before it can be marketed, and the 'two certificates and two chapters' include the "Animal Product Quarantine Certificate", "Meat Quality Inspection Certificate", "Animal Product Quarantine Seal" and "Meat Quality Inspection Certificate", all four are indispensable. Among them, the "two certificates" are registered in detail with the information of the owner, the quantity of pork, the name of the production unit and the destination, and it is necessary to check whether the information is consistent during the inspectionThe "two chapters" are printed on the meat skin, the long roller seal is the "Animal Product Quarantine Seal", and the round seal is the "Meat Quality Inspection Certificate", and these two types of seals are all blue since 2019.

The Henan netizen who was stamped with a blue pork stamp by a friend had a long strip of "Animal Product Quarantine Seal" on his face, with the words "Qualified for slaughter" written on it.
Is pork seal oil non-toxic?
Many netizens are worried that the ink on the seal of the pork will contain harmful ingredients and whether it can be eaten normallyIn this regard, the relevant departments have also explained.
Nanchang Market Supervision "This article introduces that the seal oil on pork is made of food coloring and can be eaten," the seal blue liquid is a special liquid for food blue inspection marks, which is mixed and dissolved by bright blue (commonly used as a colorant for drugs and food), alcohol, distilled water, etc. The special liquid for food blue inspection mark is an edible raw material that meets the requirements of food hygiene and will not cause any harm to the human body. ”
On the afternoon of December 1, upstream news reporters interviewed a staff member of the livestock and poultry slaughtering management office of the Henan Provincial Department of Agriculture and Rural Affairs. According to him, the composition of pork seal oil is composed of edible coloring, etc., which is not toxic and does not affect consumption.
Meat stamps "must use edible dyes". * Screenshots.
In addition, CCTV in March 2021 "Why do some pork have blue seals and some red seals?".Will there be a problem after eating?According to the report, the ink composition of pork seal includes dyes and solvents, of which methyl violet or acidic magenta, food coloring, etc., and solvents use water, alcohol, glycerin, etc., and the formula and concentration are different in different places. According to the article, China's quarantine seal used an alkaline dye called "gentian purple" a long time ago, which is the main ingredient in purple potions in life. Gentian violet adheres well to the surface of pork because it has a good affinity with the protein and is not easy to wash off. Later, studies found that gentian violet may have a carcinogenic risk, so it was eliminated and no longer used. Later, food-grade raw materials were gradually used instead, such as beet red and carmine instead of dyes, and liquor instead of alcohol. At present, the most commonly used dye is the special solution for food blue quarantine marking. Therefore, in the market now, no matter what shape it is and where it is stamped, in addition to affecting the appearance, the composition will not cause harm to the human body.
It is worth mentioning that in recent years, many regions have begun to pilot laser burning pork seals, this new way of handwriting is clear, and does not reduce the perception of pork, but the cost is relatively higher, and has not been promoted on a larger scale.
How do I get rid of seal marks?
At 8:52 p.m. on November 30, Mr. Chen, a Henan netizen whose face was stamped with pork, posted on a short **platform**, introducing the latest progress of the matter. In **, he shows the pork chapter on his face and neck, "I haven't washed it off yet, and I've tried all the methods everyone said." Thank you for your concern, and I hope you don't imitate it easily. On the morning of December 1, the upstream news reporter contacted Mr. Chen through a private message. According to him, the seal on his face has not disappeared yet, and there is no good way at the moment so he can only wait patiently.
In this regard, many netizens are curious: How can the pork chapter on Mr. Chen's face be eliminated?Some netizens said, "The pork chapter is Coomassie bright blue and can't be washed off." However, it will fade slowly, and it will take about half a month" "Pork is no longer metabolized, so it is difficult to clean the seal. And the human body is metabolizing all the time, so it won't take long for the seal to fade on its own after it is stamped on the person's body."
In the March 2021 report of CCTV, it also explained the long-lasting duration of the seal and the method of elimination, "The reason why the 'quarantine stamp' stamped on the pigskin is durable is because the pigment enters the inside of the cell. The premise of dyeing is that the pig is dead before it is stamped. The epidermis loses its vitality, no longer has metabolic function, and the pigskin is dehaired and washed, no longer has a protective isolation effect, and as the pigment gradually penetrates into the pigskin, it forms a tattoo-like appearance. However, if the 'quarantine stamp' is stamped on the human body, and the dye is isolated on the surface and cannot enter the cell, you can refer to the way that the experienced old chef treats the quarantine stamp on the pig with high liquor, and it can be washed off with hydrogen peroxide or alcohol. ”
On the afternoon of the 1st, the person in charge of a large slaughterhouse in Henan Province told reporters that the pork seal is non-toxic and food-grade, but it is really difficult to remove, "It can only be cleaned every day, and the seal will slowly disappear by itself, and it will not be able to go down for a while." ”
