With all the food and pet products now coming from China, make sure to
scrutinize the labels. But no matter what the front of a box or package
says, turn it over and study the bar code. Many products no longer show
where they were made; they show only where the distributor is located. The
bar code will show the product’s origin.

Below are the first three digits of the barcode, and where the product is
made:

00 – 09 . . . . . . . . .     USA and/or Canada.
30 – 37 . . . . . . . . .     France
40 – 44 . . . . . . . . .     Germany
49 . . . . . . . . . . . . .      Japan
50 . . . . . . . . . . . . .      UK
471 . . . . . . . . . . . .     Taiwan
690 – 692 . . . . . . .    China

Also, if a product says “made in PROC,” this is People’s Republic of
China-China.
