I have some good news for anyone who could not access their FOOD currency due to delistment on Bittrex. I was inspecting the blockchain and I found what I believed to be the Bittrex address for all the unclaimed FOOD and I inquired about their plans and if that is indeed where the are being held and support replied with "The remaining balance still belongs to the user if the coin should ever return the site." So I suppose you can still get it back since they still considered it to be yours. If it were me I would open a support ticket and provide all the relevant amounts, transactions, and addresses to prove how much you had and where and they may still send it too you.
