It is a good point. Metro in Germany, which is equivalent to our Costco in Canada, would offer a QR code. You can use your phone at the point of sale to scan the QR code and you will know exactly who caught the fish and when, when it was processed and what ingredients were added to the product before it was sold at retail. All that information is given to the consumer. Whether they want it or not, it's actually available.
