A voluntary recall of a medication to commonly used to treat blood pressure problems has now been expanded worldwide.



The U.S. Food and Drug Administration says valsartan could contain a cancer-causing chemical called N-nitrosodimethylamine (NDMA). This chemical is toxic to the liver and other organs.



According to the FDA, NDMA is found in some water supplies and in some foods. Consuming a very small amount is considered reasonably safe for humans. The amount of NDMA found in the recalled batches of valsartan exceeded these acceptable levels.

Now, the recall has gone global with the FDA adding new manufacturers to the list:
