No metal detector needed. Magnetic meat is not for sale in the U.S.

Social media users are telling consumers to think twice about buying meats from grocery store coolers, suggesting the meats contain dangerous substances.

An Aug. 6 Facebook video shows a person putting a small magnet on top of packaged beef and claiming the magnet is sticking to the meat because it contains metal.

The video also suggests this supposed magnetic beef is linked to lab-grown, or cultivated from cells, meat. The captions reads, "Lab grown meat approved for sale in America."

The person in the video also referred to lab-grown meat.

"Now that they’ve given the OK to sell lab-grown meat in the United States, I figured it would be time to return to Walmart and see if they’re still selling magnetic meat with this tiny, very strong rare-earth magnet. And right away, I found that it’s still magnetic," the person says.

This post was flagged as part of Meta’s efforts to combat false news and misinformation on its News Feed. (Read more about our partnership with Meta, which owns Facebook and Instagram.)

Keep those magnets on the refrigerator — there’s no evidence grocery store meat is magnetic.

The U.S. Department of Agriculture’s Food Safety and Inspection Service works to ensure that meat, poultry and eggs are safe to eat and properly labeled.

Meat and poultry establishments must have a Hazard Analysis and Critical Control Point system "to prevent, eliminate or reduce to a safe level any biological, chemical or physical hazard that is reasonably likely to occur in the product," an agency spokesperson told PolitiFact in a written statement.

“The CDC says that little 6 month old babies must get SEVEN doses of the Covid vaccine in order to be considered fully ‘up to date’ on their vaccinations.”

Metal pieces are a physical hazard. Many establishments install metal detectors or X-ray devices to screen their products for unexpected metal pieces. Food Safety and Inspection Service employees also conduct regular inspections to ensure products are safe for consumption.

The magnet in the video may be sticking to the packaged meat because of the meat’s texture or moisture or the angle at which the package is held. But that doesn’t mean it contains metal, a statement from the Food Safety and Inspection Service said.

Meat and poultry with the USDA inspection marker have been assessed for safety, wholesomeness and proper labeling, the statement said.

The Facebook post also mentions lab-grown meat, but currently cell-cultured meat is not sold in U.S. stores.

Cell-cultured meat is typically made by growing animal cells — which come from the tissues of living animals or a "bank" of stored cells — in steel tanks. Cultivated meat is harvested and prepared using conventional food processing and packaging methods, according to the U.S. Food and Drug Administration.

In June, the USDA gave Upside Foods and Good Meat permission to offer cell-cultivated chicken and meats. Both companies began by putting the products on the menu at restaurants owned by famous chefs.

The two companies also received FDA safety clearance to sell chicken directly grown from animal cells. Cell-cultivated beef or seafood has not been approved for sale.

FDA spokesperson Veronika Pfaeffle said that based on the manufacturing methods for these foods "there is no scientific reason or credible basis to expect that food products produced with animal cells would be magnetic."

Lab-grown meat must adhere to the same safety requirements as all other foods, Pfaeffle said.
