MINNEAPOLIS (AP) — The Sam's Club warehouse chain has pulled a brand of ground beef patties from its shelves nationwide after four children who ate the food, produced by Cargill Inc., developed E. coli illness.

Cargill asked customers to return any remaining patties purchased after Aug. 26 to the store or destroy them.

The children became ill between Sept. 10 and Sept. 20 after eating ground beef patties that were bought frozen under the name American Chef's Selection Angus Beef Patties from three Sam's Club stores in the Twin Cities area.
