1.) Be sure to check all over the package for the country the juice concentrate comes from. Look for concentrate made in the USA—it's highly regulated, making it a safer choice.
2.) Whenever possible, buy organic apple juice. None of the organic apple juices we tested came back with arsenic levels higher than the safe limit as determined by the FDA.
3.) Look for country of origin. The way countries are listed on juice boxes can be misleading. If it says "A Product of Canada," this does not necessarily mean the juice is from Canada. It could mean that the juice was packaged there or even that the box was made in Canada. On that same package, you could find another label that says, "Conc from China," meaning that the juice concentrate comes from China.
