Not all romaine. The cdc has traced back the outbreak to Yuma Arizona, stated in last report i read recently.
That, you'd have to call them directly and ask them. I doubt if they are though. However, since moving to this area ,i can say that in the 9 plus years that I've been here and passing other pizza places to eat at/order from Pizza One, i have never been sick from thier amazing food. Just a guy and his family who loves Pizza One.
