Buy pork at the wholesale market and buy "Night Pig"

The pork that was bought back by the wholesale market, even at night, emitted a flamboyant blue light. Mr. Lu, who has lived in Xiaoshengmiao Village, Tongzhou District, Beijing, has recently encountered such an embarrassing thing - he bought the "Night Pig".

Reporters witnessed the appearance of pork

At 6:30pm on the 25th, the reporter saw the piece of pork in the bungalow rented by Mr. Lu.

Less than two pounds of pork were rectangular and placed naked on a shelf. After the lights in the room were turned off, only pork on this side emitted blue fluorescence, which was evident in the dark.

Is it a fact that the special environment in the house will lead to light? To verify this, the reporter took the pork out of the house and even brought it home. He found that regardless of the environment, the pork kept its “glow” state in the dark.

In addition, the reporter noticed that the longer the pork receives light, the more pronounced the light it emits in the dark. The reporter cut a small piece of meat and put it in a plastic bag. After more than 10 minutes, the part of the plastic bag that touched the body resembled the remaining phosphor. It was also shiny.

The wholesale market to buy pork shocked at night

Lu said that this piece of pork was bought on November 19th from a meat stand at the Baliqiao Wholesale Market, with 11 pieces more than a pound and more than 3 pounds. Since there was no refrigerator in the place but there was no heating in the room and the temperature was low, Mr Luk placed the meat directly on a wooden stand in the house.

After buying it back, Mr. Lu stewed a piece of meat to eat. After eating, he felt that the stomach was not very comfortable, but he did not care too much. One or two o'clock in the morning on the 22nd, he found a thing on the wooden shelf after he had finished the toilet back to the house. When he turned on the light, he discovered that the piece of meat he had bought from the market had scared him.

"Luminous" Pork Non-caseful

In fact, Mr. Lu’s experience is not an exception.

In 2008, the newspaper reported that Mr. Lu, who lives in Daxing District, will emit a faint gleam of pork in the night at the wholesale market. In 2010, the “Sanxiang Metropolis Daily” reported in succession that citizens bought pork that would emit blue light at Carrefour supermarket in Changsha, Hunan. Earlier this year, the "Morning Morning News" reported that Ms. Chen Chen from Shanghai bought back a piece of pork that would emit blue light at night. On the Internet, there are also many netizens posting that they have bought shiny pork and asked if it will be harmful.

Experts speculate that many possible causes of light need to be identified

The reporter found that before the experts interviewed by the media, there were two major types of speculation about the cause of pork luminescence: first, excessive phosphatides were added to pig feed, and pork contained too much phosphorous; therefore, pork was slaughtered, stored, and cleaned. The luminescent bacteria that can produce luminescent substances adhere, and the metabolites of these bacteria will make the pork “glow”.

In this regard, Wei Yimin, director of the Institute of Agricultural Products Processing at the Chinese Academy of Agricultural Sciences, said that any speculation is possible without testing the physical objects. If there is a source of ultraviolet light in the home, if the wall coating contains special reflective materials Whether or not pork is subjected to radioactive contamination during storage and cutting and the above two kinds of speculation may be the “culprits” that cause pork to “glow”. However, it is better not to eat this kind of pork.

However, to really clarify the reasons, Wei suggested that Mr. Lu could send the meat to the testing center under the Shanghai Municipal Food Safety Office for testing. “However, the detection process may be very complicated.”
