Washington ? Federal health regulators Thursday fined the American Red Cross $16 million for sloppy screening of donated blood, the latest in a series of violations that have cost the group millions of dollars.

The Food and Drug Administration said in a statement that the group failed to take precautions to assure the safety of blood donations. Despite those oversights, the FDA says the U.S. blood supply appears to be safe.

Regulators fined the group nearly $10 million for mismanagement of blood products and more than $6 million for faulty manufacturing practices. The violations occurred in fiscal years 2008 and 2009.
