Bad Meat Detector

This label can helps tell the buyer beware of spoiled meat. The hour-glass shaped label is printed with a special ammonia-detecting ink that darkens according to how much of the chemical is present in the meat. The more ammonia it contains, the less fresh the meat.The darkened label also effectively obscures the product's bar code, making it impossible for it to be scanned at the checkout counter when the meat is past its prime.
