McDonald’s is recalling 29 million "Step It!" fitness trackers that were given away in some Happy Meals after reports that children experienced skin irritations and burns from the toy's wristband.

The recall comes less than a week after McDonald’s pulled the fitness tracker from its stores in the U.S. and Canada.

The fast-food giant has received more than 70 reports, including seven reports of blisters from wearing the wristbands, The U.S. Consumer Product Safety Commission said in a statement.

Last week, McDonald's spokeswoman Terri Hickey told USA TODAY, the activity trackers, which were available in all U.S. and Canadian stores would no longer be offered in Happy Meals.

“We have taken this swift and voluntary step after receiving limited reports of potential skin irritations that may be associated with wearing the band,” Hickey said in a statement.

The “Step It” fitness tracker came in six colors and strapped on like a watch. The device counted steps or blinked according to how quickly or slowly the person wearing the device was moving.

McDonald's swapped out the plush toys and figurines for the fitness trackers as part of a promotional campaign to get kids moving again in early August.

McDonald's reiterated on its website that the activity bands were tested and in compliance with federal and state requirements.

"McDonald’s is aggressively investigating this issue," the company said on its website. "While we do not yet know what may be causing these incidents, we believe it is appropriate to recall these wristbands from consumers in an abundance of caution."

McDonald’s is urging parents to take the wrist bands from their children and return them to their local McDonald’s restaurant for a new toy or apple slices.
