As a result of tests done in 2010 by the Environmental Working Group (EWG) which found 80% of apples on US produce shelves contain on average 0.42 ppm of DPA, Europe will be cutting its imports unless DPA numbers can drastically reduce. How will North Americans respond though? With there being 4 times more DPA than what’s allowable in Europe, American standards seem much more lenient and the care taken to protect citizens from hazardous chemicals is not as strict a priority.[4] Interestingly the Environmental Protection Agency (EPA) allows DPA residues of up to 10 ppm on apples -that is 100 times what is allowable in Europe!
Earlier this year three scientists in the U.S. EPA Office of Pesticides, which is tasked with pesticide safety reviews, told EWG they were unaware of the new European ban and import restrictions. They said the agency had no plans to reassess DPA safety in light of the European actions.
Although it is unknown as to whether or not DPA-treated apples present health risks, Europe has chosen to hold off until more is known about the chemical. A practice that makes perfect sense to me. Why use something potentially hazardous when one you don’t have to and two you don’t know yet if it’s safe? If you are a big apple eater, the EWG suggests buying organic.
