There may be arsenic in your morning glass of apple juice.

It's a frightening truth uncovered by a Consumer Reports investigation. While the government limits arsenic in water,  there are no limits for juices, a fact that may be even more dangerous for children.

Consumer Reports tested 28 apple juices and three grape juices purchased across several states in the New York metropolitan area. Of 88 samples, 10 percent had arsenic levels exceeding federal standards for drinking water.

With 12 juices tested, at least one sample contained levels of lead that exceed the standards for bottled water.

One likely source is agricultural pesticides containing arsenic.  Even though most are now banned, they can remain in the soil. The advocacy arm of Consumer Reports is urging the Food and Drug Administration to set standards for juice.

The juice products association says, "We are committed to providing nutritious and safe fruit juices...and will comply with limits" established by the F.D.A.          

For now, Consumer Reports says the best advice for parents is to limit how much juice your children drink. The F.D.A. says it's reviewing its own data to see if there should be guidelines for juice and, in fact, has found levels of arsenic in apple juice higher than what Consumer Reports discovered.
