(NBC) - The FDA said bacteria-ridden materials were used to make kids medicines involved in a recent recall. But testing shows no signs of contamination.
More than 50 infant and children's products are involved in the recall, including liquid Tylenol, Motrin, Benadryl and Zyrtec.
The FDA relased their report of the Pennsylvania manufacturing plant involved in the recall Tuesday.
It said some of the raw materials used to make the medications were contaminated. It also said the company failed to investigate and correct problems and didn't have proper drug testing facilities.
McNeil, the manufacturer, received nearly 50 complaints of black particles in the medicine over the past year.
FDA officials are calling these problems serious, and while McNeil has made attempts to fix them, they may take further action against the company.
