US health secretary: Chinese Heparin shipped to US now safe

Leavitt said that the need to prevent a shortage of heparin, widely used in dialysis and other common medical procedures, required that the FDA find ways to maintain the supply and quality of the drug.

"The FDA is satisfied that that which is coming into the United States is safe," he said. "Testing regimens have been put in place to ensure that."

Leavitt was due to meet later with China's minister of health to discuss various issues, including a viral outbreak that has killed at least 34 children and sickened thousands.

He said he planned to reiterate a U.S. offer to help China in its fight against the outbreaks of hand, foot and mouth disease.
