In late September, McNeil Consumer Healthcare, a division of Johnson & Johnson, announced a recall of twenty-one children's and infants' Tylenol products manufactured between April 2008 and June 2009 due to possible contamination with gram-negative bacteria Burkholderia cepacia (B. cepacia). The company stressed that the raw material in which the bacteria was found was isolated and was not used in the production of any finished product. However, it was decided, as a precaution, to recall all product that utilized any of the raw material manufactured at the same time as the raw material that tested positive for the bacteria.
