Illnesses started from May 23 to August 10.The eggs were supplied by Milo's Poultry Farms LLC in Bonduel, Wisconsin, and shipped to stores and restaurants in Illinois, Michigan and Wisconsin. The U.S. Food and Drug Administration says they may have been sent other places. The recall was announced Friday.The eggs are labeled with Milo's Poultry Farm or Tony's Fresh Market. All egg types, sizes and expiration dates are included in the recall.The recalled eggs should be thrown away or returned to the store. People should wash items and surfaces that may have touched the recalled eggs with hot, soapy water or a dishwasher.Symptoms of a salmonella infection include diarrhea, fever and stomach cramps that can start within hours or days of consuming the bacteria.
