Falsification of food products

In Japan, it has been an issue for the falsification of food products by some companies. They mislabeled the production or expiration date, and worse yet, some of them falsified the product ingredients or origins.
On the other hand, I tend to ignore the best before date or even the expiration date of foods. I dislike discarding any leftover food and so prepare a lunch box with a meal of leftovers every working day. This is the spirit of "mottai-nai". Mottai-nai means that one should not waste resources, and it represents three Rs: Recycle, Reuse, and Reduce. These food companies had also practiced these 3 Rs: they illegally recycled and reused their products, and reduced waste generation and their credibility.
I do not know whether such falsifications are common in other countries. I hear that Japanese consumers are extremely particular about the quality of food than any other countries. According to a newspaper, it seems that the Japanese Government organizes the National Food Administration.
By the way, I know that Mari wants a bigger refrigerator. But I will never accept her request while she is discarding many spoiled foods :)
