The affected sleepers are designed for babies up to 25 pounds, and have been sold at stores across the country since Sept. 2009 for between $50 and $85.
Although mold is not present at the time of purchase, mold growth can occur after using of the product.
The fungus can develop between the removable seat cushion and the hard plastic frame when it remains wet or is infrequently cleaned.
Fisher-Price has received 600 reports of mold. In 16 cases, infants were treated for respiratory issues, coughs and hives after using the sleeper.
Parents should separate the cushion from the frame and look for dark brown, gray or black spots.
If there is mold present, you should stop using the product immediately.
