Posted: 11/30/2011 - A few months ago Dr. Oz warned about arsenic... a poison that can contaminate drinking water. He was criticized for explaining that the government does not set limits on arsenic in juice... even though it does set limits for bottled water and municipal water. But now Consumer Reports says it, too is worried about arsenic levels. That's after testing apple and grape juice. In fact, it wants Uncle Sam to take action. The reason... so many children drink fruit juice.
