At least three major grocery store chains have recalled some of their ground beef packages because they could be contaminated with E. coli bacteria. 

Winn-Dixie, Publix and Kroger say problems come from the National Beef Packaging Company.  Louisiana is among several states affected.   At Kroger, the recall includes ground chuck, ground beef patties, meatballs and meat loaf made in the stores with "sell by" dates of July 29 through Aug. 12. Winn-Dixie products include ground chuck and patties with "sell-by" label dates from July 31 to Aug. 12. The companies said people should return the beef to their stores for a full refund.
