Be Careful when eating apples. Please check skin of the apples before eating because it's may be coated with wax. Check before you eat many of the fruits.
Wax is being used for preservation purposes and cold storage. You might be surprised especially apples from USA and other parts are more than one year old, though it would look fresh. Becoz wax is coated, preventing bacteria to enter. So it does not get dry. Please Eat Apples after removing the wax.
