Endangered Labels

When the meat rots, ammonia is released. The sly Japanese, who had been tormenting themselves with the stores about the shelf life of the goods, invented special labels that change color as the concentration of ammonia increases. Thus, on an expired product, the label becomes generally unreadable. After that, the product can either be thrown out, or sold to Russia, where a new, beautiful label will be stuck onto it, without any new fashionable pieces.

And what, people, come, shepherd.
