Is It Necessary To Wash Pre-Washed Greens?

The debate roils; wash or don’t wash pre-washed lettuce?

You know the stuff; pre-washed, pre-cut, bagged up and ready to use.

Is it necessary to wash it yet again for safe eating?

Indeed, many (though not all) food safety specialists advise against washing bagged lettuce or spinach. Why? First, because there’s a good chance that if bacteria managed to survive commercial-scale washing with chlorinated water in the processing plant, a lot of them will survive your home washing, too.

Disease-causing E. coli O157:H7 can get trapped just below the surface of a lettuce leaf, and they’re tough to dislodge or kill. Second, there’s a real risk that you’ll end up adding bacteria to greens that were perfectly clean to start with: Your sink or cutting board may be dirtier than the lettuce.

It looks like the only way to truly insure that you are eating the safest lettuce possible would be to cook it!
