WASHINGTON — Federal health regulators say Johnson & Johnson managers failed to test for contamination of more than 40 varieties of children's cold medicines recalled over the weekend.

An inspection report issued by the Food and Drug Administration lists more than 20 manufacturing problems found at the Fort Washington, Pa., plant where the formulas were produced.

The FDA wrapped up its inspection Friday and J&J issued its recall later that night.

FDA inspectors said the company did not have laboratory facilities to test the drug ingredients and failed to follow up on customer complaints.

The FDA previously said serious medical problems with the products are unlikely, but advised consumers to stop using the medicine as a precaution.
