To reduce exposure to parasites, follow these cleaning tips: Wash all fresh produce under clean running water, even if you plan to peel it. For leafy greens, buy whole heads instead of prewashed bags, discard the outer layers, and rinse the inner leaves thoroughly. Herbs like cilantro and basil should be separated and washed carefully. For raspberries and snow peas, rub their surfaces under running water to remove contaminants. Cooking produce when possible is the safest option.
