The state health department have traced a salmonella outbreak to the deli and bakery departments at the Wal-Mart Supercenter on North Emerson in Greenwood.

The health department has confirmed at least 84 cases of salmonella since May of this year. The store has discarded all possible contaminated food, and cleaned and sanitized both departments.

Anyone who purchased ready-to-eat items in either department on or before August 25 should throw out items, or return them to the Greenwood Wal-Mart for a refund.
