More than 1.5 million dozen shell eggs sold in six states have been voluntarily recalled over potential salmonella contamination, federal regulators announced Wednesday. The U.S. Food and Drug Administration (FDA) said Midwest Poultry Services initiated the voluntary recall, affecting 1,589,577 dozen cartons of white shell eggs and brown cage-free shell eggs. Officials said the recalled products were sold under several brands, including Kroger, Brookshire's, Country Morning, Simple Truth, and Sunups, as well as various bulk Grade A and Grade AA eggs. Consumers who purchased the recalled eggs should not eat them and should return them to the place of purchase for a full refund.
