(CNN) – Consumer reports found listeria in leafy green vegetables from a number of grocery store chains, according to a new report.
Consumer Reports bought samples of green greens from Whole Foods, Costco, Hannaford and Acme stores in Connecticut, New York and New Jersey
Of 284 samples, six were obsessed with Listeria monocytogenes – four in bundles or loose heads and two in Pre-washed, pre-packaged salad blends.
Consumer Reports points out that the sample size was not large enough to support any conclusions on the safety of specific stores or specific brands, and added that the results show that more needs to be done to ensure the safety of leafy vegetables.
The findings led to an FDA investigation, but no results have yet been published.
Health experts say that people most likely to be affected by listeria are young children, the elderly, pregnant women and people with compromised immune systems.
They say you can still eat leaf green vegetables, just stick with the cooked varieties.
Consumer reports say it decided to test leaf vegetables for bacteria after several outbreaks associated with romaine lettuce. While they found listeria, they found no other bacteria that cause food borne disease such as salmonella and E. coli.
While they say few people still have some of the products in the home, those who bought products from those stores in the middle of June should wash or disinfect their crispbreads or where the greens were stored.
