FDA Commissioner Andrew von Eschenbach is out of patience with the American Red Cross, which the FDA says isn't doing a good job with screening some of its blood supplies. In fact, according to The New York Times, between December 2006 and April 2008, the agency distributed more than 200 blood products it had already identified has potentially having problems. The agency concedes it has problems, and says it's working to fix them. In the mean time, it's toe to toe with von Eschenbach, who has threatened criminal sanctions over blood screening problems. Blog
