Indian drugmaker Fresenius Kabi Oncology Ltd has seen two batches of a cancer drug shipped to the U.S. being recalled by its German parent, Fresenius Kabi Pharmaceuticals Holdin Inc, the Economic Times reported on Monday.

The drug anastrozole tablets, used to treat breast cancer, was recalled after the German drugmaker found cross contamination but financial details of the recall were not available, the report said.

The firm has recalled 7,192 bottles, each containing 30 1-mg tablets set to expire in May next year, it said.

Officials of the company could not be immediately reached for a comment by Reuters.
