Last week's McDonald's debacle, which saw the fast food giant forced to recall its first wearable tracker, has taken yet another turn, this time involving the U.S. government. 。

On Tuesday, the U.S. Consumer Product Safety Commission (CPSC) followed McDonald's recall of the device with its own official warning to consumers, and revealed a few facts that we didn't have before. 。

According to the CPSC, McDonald's had roughly 29 million Step-It devices in the U.S. and 3.6 million units in Canada.。

Of the units that actually made it onto the wrists of consumers, there were more "70 reports of incidents, including seven reports of blisters," after users put the wearable devices on their wrists.。

The CPSC also confirmed that the devices were manufactured in China.。

Kaye said in a statement emailed to

"McDonald's is giving consumers a replacement toy as well as an incentive. Act now. We do not want any more children to experience rashes or blisters from these recalled products." 。

The CPSC notice also notes that consumers not interested in a replacement toy can also return the devices to McDonald's in exchange for a "yogurt tube or bag of apple slices."。TopicsFitness Trackers。TopicsFitness Trackers 。
