How should vegetables be washed before preparation?

Washing vegetables under cold running water is the best practice to remove dirt, contaminants, and pesticide residues. This method not only helps in cleaning the surface effectively but also ensures that any microorganisms present are rinsed away. Cold water is typically sufficient for this task, as it avoids cooking the vegetables, which could happen with hot water soaking. Additionally, using cold water for rinsing preserves the fresh texture and quality of the vegetables, making them more appealing and safer for consumption. Most food safety guidelines recommend this approach, making it the standard procedure for preparing vegetables prior to cooking or serving.
