I swear I saw a couple of cartons of hot dogs at my college cafeteria labeled "Grade Edible" one day. Not coincidentally, also the last day I stayed on the meal plan. The interwebs claim this food grade designation never existed, but I know what I saw, and the year was 1988. Given how sick that cafeteria food often made me feel, I question the accuracy of that grading. Probably belonged in the OP's photo container.
