More than 70 people across seven states have been sickened due to a salmonella outbreak linked to eggs recalled by a California-based egg distributor, according to the US Centers for Disease Control and Prevention.

A major egg recall involving products sold at Walmart, Safeway and other retailers in nine states has been issued after a salmonella outbreak was blamed for 21 hospitalizations.

The Hilmar-based company recalled 1.7 million dozen brown cage-free and brown certified organic eggs distributed to retail stores in California and Nevada, including Safeway, Raley’s, Food 4 Less, Lucky, Save Mart, FoodMaxx and Ralphs.
