Food items in general have a particular shelf life. Even the natural fruits and vegetables have to be consumed as fresh as possible or there is a chance of spoilage of such fresh fruits and vegetables in spite of keeping under refrigeration conditions. The condition where the food is unsuitable for consumption any more is termed as Expiry of Food. This expiry of food is especially related to packaged food items which are anyways preserved with artificial preservatives. Though our busy lifestyles have led us to consume such packaged foods often, it is important to understand what happens if we eat expired food products?
