No they aren't. Some are but not many. Hell groceries at most grocery stores don't comefrom America, read the labels on them. IIRC a lot of fruits and vegetables at big chains like that except for from peak season come from south america. I've never been to Walmart and looked at their produce and said man does that look good. Of course I regularly shop at Farmers Markets and Co-ops so I'm used to good looking produce that isn't pumped full of nastiness.
