KANSAS CITY, Mo. (AP) _ U.S. Agriculture Secretary Ed Schafer says a decision by the two biggest U.S. warehouse chains to limit how much rice customers can buy is driven by emotion.
During a visit to Kansas City Thursday, Schafer said there's no evidence that rice is in short supply.
Wednesday, Wal-Mart Stores division Sam's Club said it would limit customers to four bags at a time of certain types of rice. That followed a decision by Costco to limit bulk rice purchases in some of its stores.
In a news conference, Schafer said there is no evidence of a shortage of rice in the world. But he acknowledged some countries' concern about food security.
