Wal-Mart Calls On Suppliers To Treat Farm Animals Better

Wal-Mart, the country's largest food retailer, is calling on its thousands of suppliers in the U.S. to treat farm animals better, and give them fewer antibiotics.

The guidelines are voluntary, but Wal-Mart wants suppliers to report on their progress in an annual report and on company websites.

The news comes as Wal-Mart faces pressure from the animal rights group Mercy for Animals, which had found mistreatment of pigs at certain farms that supply pork to Wal-Mart.

Here & Now's Meghna Chakrabarti speaks with Michael Regan, editor at Bloomberg News, about what the decision means for Wal-Mart's business.
