I cant speak for every Amazon warehouse but @ Jax2 FC, I've personally worked a role in Vendor Returns, where we would remove, return and/or destroy expired food and candy that has sat in the warehouse for too long. Most of the food that was removed, was on its way to being expired in a few weeks and it was removed well before the expiration date. Some of it gets donated if its still good and the expired goods get destroyed in the trash. - BrianD.J, Amazon FC Ambassador
