Wash That Pre-Washed Salad

Consumer Reports' March issue has an article about the bagged salads we buy (to make getting in those 5 to 7 daily servings of veggies a bit easier) being loaded with fecal contamination. You can read the full article here, but here is a sample:
You might think that "pre­washed" and "triple-washed" salad greens sold in plastic clamshells or bags are squeaky clean. But our recent tests found room for improvement....But in our samples, all of which were within their use-by date, we did find bacteria that are common indicators of poor sanitation and fecal contamination—in some cases, at rather high levels....We tested for total coliforms and for other bacteria, including enterococcus, that are better indicators of fecal contamination. Federal action limits exist for indicator organisms in water, raw meat, milk, and some processed foods, but not produce. Those organisms are typically used to gauge possible pathogen contamination.

There are no federal limits for bacteria in produce? Did I read that? Senate Bill 510 "The Food Safety Modernization Act" is being considered to set stronger safety standards for produce. Considered? How much consideration is needed to decide if you want poop in your salad?

The article includes a "what you can do" section:
* Buy packages as far from their use-by date as you can find.
* Even if the bag says "prewashed" or "triple-washed," wash the greens yourself. Rinsing won't remove all bacteria but may remove residual soil. 
* Prevent cross contamination by keeping greens away from raw meat. For more information, go to www.ConsumersUnion.org/safefood.
