PHILADELPHIA — A subsidiary of Johnson & Johnson has pleaded guilty to a federal criminal charge that it sold infants' and children's liquid medications that contained metal particles.

McNeil Consumer Healthcare, of Fort Washington, Pennsylvania, acknowledged producing adulterated bottles of Infants' and Children's Tylenol and Children's Motrin. The company agreed to pay $25 million to resolve the case.

Court documents say metal particles, including nickel, iron and chromium, were introduced during the manufacturing process in 2009 and 2010. Prosecutors said McNeil failed to take immediate steps to fix the problem.

The company and prosecutors said Tuesday that no one was injured.
