Talking about the same, Mayur Rastogi, Assistant Professor, Nutrition and Dietetics Department, Sharda University, shared some tips on how E. coli risk can be dodged.

“In light of recent concerns surrounding E. coli outbreaks linked to lettuce leaves, ensuring their safety through proper cleaning is paramount. According to experts, thorough washing is essential to minimie the risk of contamination. Begin by rinsing the lettuce under cool, running water. This step helps remove any visible dirt or debris. Next, gently separate the leaves to ensure water reaches all surfaces. Pay particular attention to crevices where dirt can accumulate, said the expert.

“After rinsing, consider using a produce brush for firmer leaves like romaine to further dislodge impurities. Alternatively, soaking the leaves in a solution of vinegar and water (one part vinegar to three parts water) for a few minutes can help kill bacteria. Rinse thoroughly afterward to remove any residual vinegar taste. For added precaution, ensure all utensils and cutting boards used for handling lettuce are clean and sanitized. Store lettuce in the refrigerator at temperatures below 40°F (4°C) to slow bacterial growth,” Rastogi added.

The expert concluded by saying that one must discard outer leaves that appear wilted or damaged, as they may harbor more bacteria. By following these steps diligently, you can enjoy your lettuce while minimizing the risk of foodborne illnesses. In conclusion, while recent outbreaks underscore the importance of careful handling, properly cleaned and prepared lettuce remains a safe and nutritious addition to your diet.
