UNDATED - It's something to think about as you pour that glass of apple juice: a new investigation says there's potential danger lurking in that glass.
Consumer Reports did its own investigation testing both apple and grape juice. The results were released Wednesday.
They found 10 percent of the juices had arsenic levels greater than the Federal standard for drinking water and a quarter had lead levels higher than the standard for bottled water.
The findings raise questions about how the FDA evaluates the levels of contaminants in the juices. The Juice Products Association says their products are different than bottled water and to compare the two "is not appropriate."
Earlier this year, TV medical personality Dr. Mehmet Oz and ABC medical correspondent Dr. Richard Besser got into a heated argument on the Good Morning America news program following a controversial report by Dr. Oz that some apple juice contained arsenic.
Dr. Oz was accused of fear mongering over the arsenic claims by Dr. Besser. Dr. Oz stood by his claims.
The FDA released a statement after the findings were released, saying in part "a small percentage of samples contained elevated levels of arsenic. In response, FDA has expanded our surveillance activities and is collecting additional data."
