The Associated Press reported today that the South Dakota Health Department announced that the Centers for Disease Control and health officials in South Dakota and three other states are investigating an outbreak of Salmonella Newport. In South Dakota, cases were reported in nine adults and two children in the Black Hills area. Six required hospitalization.

Perhaps the other three States are Montana, Pennsylvania and Texas?  According to KULR TV in Billings:

Some people in Yellowstone County are infected with Salmonella; the same strain that is making people sick in states as far away as Texas and Pennsylvania. Now, the Yellowstone County Health Department is trying to figure out how they are connected.

Or, as perhaps suggested to me by the Foodsnark, this might be tied to the Salmonella Newport outbreak linked to Safeway in December.
