Q: Do you have to wash pre-cut lettuce and bagged salads?
Oz says: If the wrapper says it's been washed, there's no need to douse it again. The chance of contracting a food-borne illness from E. coli or salmonella in your precleaned packaged greens is minuscule, says Luke LaBorde, Ph.D., an associate professor of food science at Penn State University.
And even if the leaves harbor bad bacteria, rinsing probably won't remove all of them because they can stick to the nooks and crannies of produce. If you're going to wash anything, says LaBorde, make it your hands, since you're less likely to get sick from the greens than from cross-contaminating food after touching germy kids, pets, or a cutting board recently used for raw meat.
