Working in collaboration with the Consumer Products Safety Commission (CPSC), McDonald’s has announced a recall of “Step-iT” activity wristbands for causing skin irritation and burns to children. Available with Happy Meals and Mighty Kids Meals, about 29 million units were distributed in the U.S. and 3.6 million in Canada between August 9 and August 17.

McDonalds has received more than 70 injury reports regarding the wristbands, including seven involving blisters.

The China-manufactured wristbands involved in the recall come in two styles: “Activity Counter” and a motion-activated “Light-up Band.” The Activity Counter comes in translucent plastic orange, blue or green, and features a digital screen that tracks a child’s steps or other movement. The Light-up Band comes in translucent plastic red, purple or orange, and blinks light with the child’s movement. Both styles of activity wristbands have a square face with the words “STEP-iT” printed on them and a button to depress and activate the wristband. The back of the square face contains the etched words “Made for McDonald’s.”

McDonalds is advising consumers to take the recalled wristbands from children and return them to any McDonald’s. They will receive a free replacement toy and either a yogurt tube or bag of apple slices in return. For more information, McDonald’s can be reached at 800-244-6227, 7 am to 7 pm CT daily, or online at www.mcdonalds.com; click on “Safety Recall.”
