The Hello Kitty whistle in McDonald's Happy Meal has been recalled by the U.S. Consumer Product Safety Commission saying 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.

The toys were in Happy Meals and Mighty Kids Meals in October and November.

Consumers should return the whistle to any McDonald's for a free replacement toy.
