U.S. product regulators said Thursday that Yeti has recalled 1.9 million coolers and gear cases because magnets can come detached from them, posing a risk of serious injury or death.

The Consumer Product Safety Commission said consumers should immediately stop using the four recalled products and contact Yeti for refund information.

The closures on the recalled products can fail, resulting in detached magnets, the CPSC said. If swallowed, two or more high-powered magnets can attract to each other or to another metal object and get stuck in the digestive system. The CPSC said if that happens, it can cause perforations, twisting and blockage of the intestines, potentially resulting in infection, blood poisoning and death.

The products being recalled are the Sidekick dry gear case, M20 soft backpack cooler and M30 soft cooler, version 1.0 and 2.0.

The coolers and gear bags were sold at Dick’s Sporting Goods, Ace Hardware, Academy Sports and Outdoors, Yeti and other stores, including Amazon, from March 2018 to January 2023. The gear case sells for about $50 and the coolers for between $300 and $350.

The firm has received 1,399 reports of the magnet-lined closures degrading or failing, including reports of missing or detached magnets. No magnet ingestions or injuries have been reported.
