Today’s USA Today has several terrific stories about how hard it is to know where our food comes from and why it matters that we do. The cover story in the Life section follows Phil Lempert, the supermarket guru, around a store reading package labels to try to figure out the origins of ingredients. A second piece lists where specific foods come from. Dairy, peanut butter, bread, and soda pop are All-American, but Brazil is the number one source of orange juice. And who knew that fresh and frozen fruits and vegetables head the list of imported foods and Mexico is the leading source? A third story, in which I am quoted, discusses Country of Origin Labeling (COOL), a law passed by Congress years ago but endlessly postponed under pressure from food industries. Only supermarket fish are required to list the country that caught or farmed them, and as far as I can tell, this is a law ignored more often than not. If Congress doesn’t get its act together and put COOL into action, we won’t have a clue where our food comes from. Why do we need to know? Safety and miles traveled, for starters. Ever heard of COOL? It’s worth writing your representatives for this one.
