Bagged Greens Pose Real Safety Risks, Experts Warn

A HuffPost piece explains that prewashed bagged greens are among the riskiest grocery items due to contamination by pathogens like E. coli, listeria, and salmonella, which can spread across the supply chain. Washing at home doesn’t reliably remove these pathogens, and mixing greens from multiple farms in processing can amplify spread. For safer shopping, check recalls and expiration dates, choose visibly fresh bags with minimal moisture, minimize temperature changes, and refrigerate properly; buying whole heads of lettuce or spinach can reduce risk. If you must buy bagged greens, follow precautionary steps and discard any bags that show signs of spoilage or recalls.
