Salad - Eat Fresh,else leave

Always eat fresh salad,otherwise it may cause some kind of stomach infection.In a hurry,people use to cut salad before the guests arrive,it may be 1,2 hours before.But i tell you please eat fresh salad which is 10-12 min old otherwise avoid eating it.
It has no essential ingredients left over no sooner it becomes 15 min old,rather it may be dangerous for your health.
Take care.:):)
