E. Coli recalls: See map of recalled ground beef and walnuts

E. Coli recalls have been issued in 20 states and DC for ground beef and walnuts potentially contaminated with the bacteria. Cargill Meat Solutions recalled over 16,000 pounds of ground beef, while Gibson Farms, Inc. recalled organic walnut halves and pieces linked to infections in California and Washington. The recalls do not overlap geographically, with the ground beef distributed to Walmart stores in the East and the walnuts sent to stores primarily in the Midwest and West Coast.
