Wal-Mart milk to cut out growth hormones

Wal-Mart Stores Inc said on Thursday that its private-label Great Value milk is now being sourced only from cows that have not been treated with artificial growth hormones, such as recombinant bovine somatotropin (rbST).

The retailer said its Sam’s Club chain also is offering milk selections from suppliers that have pledged not to treat cows with rbST.

While the U.S. Food and Drug Administration has said that milk from cows treated with rbST poses no risk to human health, Wal-Mart said it made the change in response to customer demand.
