The research includes items from McDonald’s, Burger King, Pizza Hut, Domino’s, Taco Bell and Chipotle locations in San Antonio, Texas. Researchers obtained 64 food samples of hamburgers, fries, chicken nuggets, chicken burritos and cheese pizza from the chains.
They found that over 80% of the foods contained a phthalate called DnBP. And 70% contained the phthalate DEHP. Both of the chemicals have been linked to reproductive health problems.
