McDonald’s is recalling a Hello Kitty-themed whistle given to children in Happy Meals, citing a chance they could choke on some of its parts. The toys were in Happy Meals and Mighty Kids Meals in the U.S. and Canada in October and November. The U.S. Consumer Product Safety Commission said Monday that two children have reportedly coughed out pieces of the whistle that they had sucked into their mouths, including one child who received medical attention. The safety agency said that parts of the three-inch-tall “Hello Kitty Birthday Lollipop” whistle can detach and be inhaled, posing a risk to small children.
