According to the Environmental Walking Group, non-organic lettuce has the 8th highest amount of pesticide residue of 43 of the most common fruits and vegetables so it is best to choose organic romaine lettuce.
Store romaine lettuce in a plastic bag in the refrigerator with a damp paper towel wrapped around the root. Romaine can remain fresh for as long as a week.
