Hi Z,
Thank you. I did check out the site you mentioned, and you are correct.
snopes.com: Determining Product Origins by Bar Code
I would suggest others go to this site. Snopes gave this posting partially true and false. That means there is a mixture of true and false information.
There is a lot of information they included in their review of the bar codes.
At my age I should have known better, than to accept automatically what I read. I usually do, and for some reason I did not this time.
