The government is warning parents about Carter's Inc. baby garments with tag-less labels after about 400 babies who wore the clothing developed rashes on their backs.

The warning applies to the fall 2007 line, which includes about 110 million garments, said Mary Drayna, a manager for the Atlanta company. The Consumer Product Safety Commission said Friday that children should stop using these garments if they develop a rash, but the agency did not announce a recall of the product line.

Drayna said the affected clothing includes knit items such as body suits, shirts and pajamas. She said the items have prompted about 400 reports of baby rashes, but she could not comment on how serious any of the rashes were or if any required hospital visits.

The garments were made in various foreign countries, and they were sold at Carter's retail stores and at department and national chain stores, according to CPSC. The clothing appeared on the market in the fall of 2007 and could still be on retail shelves, although Carter's has released other products since then, Drayna said.
