More than 2 million Hello Kitty whistles distributed with McDonald's meals have been recalled because they pose a choking hazard to young children. Other recalled consumer products this week include misting fans with bad wiring and water heaters that can cause a fire.

Here's a more detailed look:

WHISTLES

DETAILS: Hello Kitty Birthday Lollipop Whistles distributed exclusively at McDonald's restaurants nationwide from October 2014 through the first week of November 2014 with Happy Meals and Mighty Kids Meals. A picture of Hello Kitty appears on both sides of the whistle. The text "(copyright)1976, 2014 SANRIO CO., LTD." appears above Hello Kitty's face on the whistle, and "Made for McDonald's China CCW Chine" appears below Hello Kitty's face on the whistle. The bag in which the toy is packaged includes the text "Hello Kitty Birthday Lollipop" and the number "6'' in the upper right corner.

WHY: Components inside of the whistle can detach, posing choking and aspiration hazards to young children.

INCIDENTS: McDonald's has received two reports of children who coughed out pieces of the whistle that they had sucked into their mouths, including one child who received medical attention.
