[I usually shop at Walmart.]
Start reading the labels of origin at Walmart:
* 100% Juice canned fruit; processed in China.
* Fresh chicken; processed in China.
* Fresh fish; caught in the Pacific (China)
Does China process human food like it does dog food?
I still shop Walmart, but I am more choosy about what I buy.
What brands are you talking about, and what do the labels say differently at other stores?
