Rules for a safe salad

Always wash hands thoroughly before and after handling raw food, including vegetables.
Keep raw foods, including vegetables, separate from ready-to-eat foods.
Use different chopping boards, knives and utensils for raw and ready-to-eat foods, or wash them thoroughly in between preparing different foods.
Unless packaging around vegetables says ‘ready to eat’ you must wash, peel or cook them before consuming.
To wash vegetables, immerse them in cold water.
