Next time you make a salad at home, you might want to give those greens an extra rinse.

Despite salad greens being labeled "pre-washed," Consumer Reports found elevated levels of bacteria and is suggesting it's probably best for consumers to give their greens another wash before consuming.

Taking a look at a small sample of greens, the publication found bacteria which indicate "poor sanitation and fecal contamination."

The testing did not find E. coli, listeria or salmonella. The publication said it did not expect to find those sort of contaminants.

The tests were performed last fall at an outside lab and received financial support from the Pew Health Group.
