WESLACO – In light of a national warning from health officials, a Texas grocery retailer is removing romaine lettuce products from its shelves.

H-E-B announced the removal of all romaine lettuce products from its stores after the U.S. Food and Drug Administration issued an alert to suppliers and retailers to remove the produce harvested from Salinas, California.

On Friday, the FDA reported they are investigating an E. coli outbreak which has affected 40 people in 16 states.

The agency has deployed investigators to Salinas farms.

H-E-B is asking its customers to dispose of romaine lettuce products or they can return it for a full refund.
