Three people in Minnesota have reportedly fallen ill with Salmonella poisoning in connection to a multistate outbreak involving live poultry first reported by Food Safety News on Monday. Each of the three Minnesota patients reportedly purchased ducklings from Tractor Supply Co. in Inver Grove Hieghts, Minn., according to the state department of health. Yesterday, the South Dakota Department of Health announced four Salmonella illnesses in that state, which are suspected to be connected to live chicks. The Minnesota Department of Health identified the outbreak serotype as Salmonella Infantis. The Minnesota patients reportedly fell ill between late March and early April. Their ages range from 18 to 60 years. It is not clear whether any more states are affected by the outbreak. The U.S. Centers for Disease Control is currently investigating the illnesses, but is not prepared to make any announcements, CDC spokeswoman Lola Russell told Food Safety News on Monday.
