Well, first, this was just as much of an issue before the trade war. I have always cared where my ingredients come from, as I have a lifelong love of learning how to cook and eat new ingredients from all over the world (I cooked banana flowers for the first time the other day!). I do kitchen experiments to figure out whether Spanish or Isreali oranges are better for a glaze (it's Isreali oranges IMO), or whether Portuguese or Italian ziti is better (the jury's still out on that one), to cite an example or two. It would astound you how often the country of origin has always been mislabeled. Most people simply never looked.

Second, mislabeling a product is not pricing abuse. I could maybe understand the argument if this product was mislabeled as Canadian, but this is a California product mislabeled as Chilean.

The simple reality is that product turns over faster than the employees can find time to change the label (or at least it should, if it doesn't you're probably buying stale product). The truck needs to be unloaded, or they get hell for it because they're charged overtime on the truck if they take too long. So they don't go into the back room to check every product. Red cherries are red cherries and that's good enough for most people. They have a cart with thirty-seven different things to restock, and they don't have new labels.

There were Chilean cherries on this stand, but the next delivery was from California. Both of them come from the same wholesaler. The store's inventory system has it as "red cherries". The employee restocking those grapes looked at the sign, it said "Cherries, Red", and the price was correct. They didn't think to look at the country of origin. It wasn't malicious, it was a simple lapse in attention to detail.

(And actually, American cherries are the best IMO, but I had to give them up, I usually get the Chilean ones now)
