"Through an abundance of caution," notes the US Food and Drug Administration, "Rose Acre Farms of Seymour, Indiana is voluntarily recalling 206,749,248 eggs because they have the potential to be contaminated with Salmonella Braenderup, an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems."

States which are affected by this recall include Colorado, Florida, New Jersey, New York, North Carolina, Pennsylvania, South Carolina, Virginia and West Virginia. The recall includes eggs sent to both stores and restaurants, with 22 consumers reporting illness thus far.

The FDA emphasises that this recall was voluntary and followed an FDA inspection of the farm which is reported to have approximately 3 million laying hens producing 2.3 million eggs a day with a USDA inspector undertaking daily inspections.

The FDA notes, "Consumers who have purchased shells eggs are urged to immediately discontinue use of the recalled eggs and to return them to the place of purchase for a full refund. Consumers with questions may contact the company at +1 (855) 215-5730 between the hours of 8 am to 5 pm Eastern Standard time."
