Conair is expanding a recall of Cuisinart metal wire-bristle grill brushes after reports that bristles detached and, in some cases, were swallowed by consumers.

The recall now covers about 3.6 million brushes, according to the U.S. Consumer Product Safety Commission. About 1.9 million additional brushes were added Thursday to the nearly 1.72 million recalled in July.

Small metal bristles can detach from the brushes and stick to grills or food, creating an ingestion hazard and a risk of serious internal injuries that could require surgery.

Conair is aware of at least 54 reports and reviews involving detached bristles. Three consumers swallowed metal bristles and sought medical treatment to have them removed from their digestive tracts or throats, according to the CPSC.

The expanded recall covers all Cuisinart wire-bristle grill brushes, including numerous models sold individually and as part of grill tool sets. The brushes were sold at Walmart, Burlington, TJ Maxx and Ross, as well as online through Amazon and Cuisinart, from June 2009 through March 2026 for between $8 and $20.

The CPSC said consumers should immediately stop using the recalled brushes and contact Conair for a full refund or a Cuisinart.com credit worth the refund amount plus 20%. Consumers will be asked to discard the brushes.
