Three types of cottage cheese sold under Walmart's "Great Value" brand are being recalled in two dozen states because they may not have been pasteurized properly.

The Food and Drug Administration said the cheese’s manufacturer, Saputo Cheese USA, discovered the issue during what it called "pasteurizer troubleshooting exercises." It then voluntarily issued the recall.
