McDonald's removes fitness tracker from Happy Meals

McDonald's is removing fitness trackers from Happy Meals due to concerns over skin irritations and possible burns.

"We have taken this swift and voluntary step after receiving limited reports of potential skin irritations that may be associated from wearing the band," company spokeswoman Terri Hickey said in the statement. "Nothing is more important to us than the safety of our customers and we are fully investigating this issue."

The exact number of reports was not specified.

The Step-It activity trackers were being distributed and were set to continue to be available for four weeks in the United States and Canada. The plastic wrist-worn pedometer measures steps and blinks quickly or slowly depending on the pace of the person wearing it.

Hickey has not replied to requests for additional information, including the manufacturer of the activity trackers.
