what makes you think that Kroger's/ HEB / Randall's won’t parcel this out to China? What about all of the products that only list "Distributed by XXX, New Jersey"? There's no way to track that stuff.
Actually some of the cans at Walmart do state something to the effect that the product was developed in China. I do think you have a point about other businesses though. I’m sure theirs are labeled too, if Walmarts are.
Good point.
