The FDA is investigating several outbreaks of E Coli due to chopped romaine lettuce. There are not many details known, but there have been 35 cases in 11 states, all linked back to romaine lettuce from sourced Yuma, AZ.
If you have any in your fridge currently and you don’t know it’s origin, you may want to toss it to be safe. It’s unknown if organic lettuce is included in the recall, so play it safe and avoid it until more details come out.
