At least two people in California fell ill with a salmonella infection after eating eggs linked to a Wisconsin company, according to the U.S. Food and Drug Administration. The salmonella outbreak is associated with Milo's Poultry Farm, LLC, of Bonduel.At least 65 people have been infected across nine states, as of Sept. 6. That includes Colorado, Iowa, Illinois, Michigan, Minnesota, Utah, Virginia and Wisconsin. The eggs are branded as Milo's Poultry Farms and Tony's Fresh Market. They were distributed to restaurants and retailers in Wisconsin, Illinois and Michigan, but the FDA says the product could have made its way to additional states. Forty-two of the salmonella cases are in Wisconsin. Our partner SFGATE reported that the FDA upgraded the recall to its highest classification, Class 1, on Sept. 30.Class 1 is "a situation in which there is a reasonable probability that the use of, or exposure to, a violative product will cause serious adverse health consequences or death," according to the FDA's website. The initial recall involved 108,115 cartons of a dozen eggs. It has since been upgraded to 345,417 cartons. The product subject to the recall has a "best by" date of Oct. 12, 2024, or earlier. People usually fall ill from a salmonella infection about 12 to 72 hours after eating the contaminated food and symptoms last anywhere from four days to a week, according to the FDA. Common symptoms are diarrhea, fever and abdominal cramps. Children under 5 years old, the elderly and people with weakened immune systems are most at risk of serious illness. People are urged to throw out the product.See more coverage of top California stories here | Download our app | Subscribe to our morning newsletter
