The activity trackers McDonald's included in its Happy Meals this month are causing blisters and skin irritation on people's wrists.
The U.S. Consumer Product Safety Commission (CPSC) says the fast food chain is voluntarily recalling 29 million Step-iT activity wristbands in the United States (plus 3.6 million in Canada) after receiving more than 70 reports of incidents, including seven reports of blisters.
"Nothing is more important to us than the safety and well-being of our customers which is why upon learning about concerns with these bands we acted swiftly to stop distribution of these products," Terri Hickey, a spokesperson for McDonald's, said in a news release.
The wristbands – which come in two styles: Activity Counter and a motion-activated Light-up Band – were sold in Happy Meals and Mighty Kids Meals nationwide from Aug. 9 to Aug. 17, the CPSC says.
People are asked to "immediately" take the wristbands away from children and return them to McDonald's for a different toy. They'll also get to choose from either a yogurt tube or bag of apple slices.
