Oz said on his show this week that testing by a New Jersey lab has found what he implied are concerning levels of arsenic in many juices.
However, the FDA says the lab methods were not appropriate and that its own tests show much lower arsenic levels. The agency warned the show's producers in advance that their testing was misleading.
Dr. Richard Besser, former acting head of the Centers for Disease Control and Prevention, also scolded Oz Thursday on ABC's "Good Morning America" show for scaring consumers with what Besser called an "extremely irresponsible" report.
