Consumer Reports: Time for bagged salad to come clean

A new survey in the March edition of Consumer Reports suggests that consumers should wash packaged greens or salad even if the packaging states that it has been pre-washed.
The consumer advocacy group used an independent lab to test 208 bags of salad from 16 brands sold in New York, Connecticut and New Jersey. It discovered that 39 percent contained high levels of coliforms, a potential indicator of fecal contamination. The study did not find disease-causing bacteria,such as E.Coli, listeria or salmonella.
