Sixteen people across five states have fallen ill from Salmonella poisoning, several from a raw ground-beef dish served at a Michigan-based restaurant, the U.S. Centers for Disease Control and Prevention said on Monday.

Local, state and federal health and regulatory officials said the likely cause of the Salmonella Typhimurium outbreak was Jouni Meats Inc, of Sterling Heights, Mich., and Gab Halal Foods, of Troy, Mich.

Most the people sickened were in the Midwest -- two in Illinois, one in Iowa, three in Wisconsin and nine in Michigan -- where the meat shops are located, the CDC said. One sick person was identified in Arizona.

Seven people reported eating a raw ground-beef dish at a restaurant, the CDC said, adding that roughly half of the people were hospitalized, although none died.
