Cookouts and bonfires are summer pastimes, and health experts are urging people to enjoy them responsibly. In addition to the risk of burns from grills and other cooking equipment, the metal wires from grill brushes can be dangerous. Those wires can become embedded in food on the cooktop and send people to the ER with tooth and mouth injuries or even bristles stuck in their throat. Emergency physicians say to take extra care when buying and using a grill brush.
