Iowa-based Wright County Egg expanded its voluntary recall on Wednesday to 380 million eggs produced at all five Wright County Egg farms because they have the potential to be contaminated with Salmonella.

In June and July, more than 200 cases were reported weekly – four times the normal amount – with illnesses in California, Minnesota, and Colorado linked to the eggs. An estimated 1300 people have become ill due to the contamination. No deaths have been reported. State and local partners are also investigating human Salmonella infections in Arizona, Connecticut, Massachusetts, Maryland, North Carolina, Nevada, Oregon, Pennsylvania, Tennessee and Texas.

Wednesday’s announcement expanded the recall to Arizona, Texas, Georgia, Washington, Oregon, Nevada, Utah, Arkansas and Oklahoma. Eggs affected by the recall were distributed to food wholesalers, distribution centers, and foodservice companies in California, Illinois, Missouri, Colorado, Nebraska, Minnesota, Wisconsin, and Iowa. These companies distribute nationwide.

The brand names James Farms, Glenview and Pacific Coast were added to the recall on Wednesday. Wright County eggs are packaged under the brand names: Lucerne, Albertsons, Mountain Dairy, Ralph’s, Boomsma’s, Sunshine, Hillandale, Trafficanda, Farm Fresh, Shoreland, Lund, Dutch Farms and Kemps. The eggs are packed in 6, 12, and 18-egg cartons with Julian dates ranging from 136 to 229 and plant numbers 1026, 1413, 1720, 1942 and 1946. The dates and codes can be found stamped on the end of the egg carton. The plant number begins with the letter P and then the number. The Julian date follows the plant number, for example: P-1946 223.
