Federal safety regulators warned consumers to stop using high-powered magnetic ball toy sets that have been linked to seven deaths and hundreds of injuries.

The Consumer Product Safety Commission flagged six children’s products that do not comply with U.S. safety regulations because they contain magnets small enough to fit down a child’s throat. The agency pointed to seven deaths — including five in the United States — involving people who ingested the tiny magnets, as well as an estimated 2,400 emergency hospitalizations from 2017 through 2021.
