Despite the recent massive recalls of eggs due to salmonella contamination, frittatas are thought to be safe because the eggs are thoroughly cooked. To be even safer, avoid eggs that were packed by the involved farms; they may be sold under a range of labels including: Lucerne, Albertson's, Mountain Dairy, Ralph's, Boomsma's, Sunshine, Hillandale, Trafficanda, Farm Fresh, Shoreland, Lund, Dutch Farms and Kemps. Keep eggs refrigerated. Don't use any eggs coming from cracked shells. And of course, keep all work surfaces clean and wash your hands thoroughly after using raw eggs.
