American apples are back in the news. The concern? Diphenylamine, or DPA, a pesticide applied to apples after they’re harvested to help prevent browning. Its use was enough to prompt action from the European Union.
Correction, April 29, 2014: This video originally misstated the parts per million acceptable for diphenylamine on U.S. and European apples. The U.S. limit is 10 ppm; it is 0.1 ppm in the European Union.
