A second Iowa egg producer has been implicated as a possible source for the recent rise in salmanella cases. Hillendale Farms of Iowa has recalled 170 million eggs distributed since April 9 2010 after epidemiologists linked the eggs to a salmonella outbreak in May. The eggs recalled  were sold under the farm’s own name as well as Sunny Farms, Sunny Meadow, Wholesome Farms and West Creek and were distributed  in California, Arkansas, Iowa, Illinois, Indiana, Kansas, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, Texas, and Wisconsin. Another Iowa company, Wright County Egg,  has already recalled 380 million eggs. This brings the total to more than one half billion eggs being recalled. The outbreak occurred as new FDA egg-safety rules came into effect in early July. The new rule requires producers to test more for salmonella, as well as take other precautions. It is hoped the new rule will lessen the risk of salmonella in eggs.
