I'd be surprised that washing lettuce prevents the second, but I'm open to evidence that it does.
But there's a lot of ambient food poisoning that can be prevented by washing lettuce, especially in reducing cross-contamination (the lettuce wasn't contaminated, then got exposed during the cooking prep process, etc.)
