Panera Bread, a self-proclaimed proprietor of "good food" and "clean, wholesome foods," contained the highest levels of glyphosate in two samples.
Arby's sandwiches came in at the second-highest levels.
Dairy Queen and Little Caesar's were nearly tied for third third-highest total glyphosate detected.
Meals from Chipotle, one of the first fast-food restaurants to advertise non-GMO and organic ingredients, were found to have the lowest levels, which is 94.4 times lower than the highest levels detected in Panera Bread.
Meals from Panda Express and McDonald's were the next lowest levels.
Meanwhile, the laboratory noted these observations during pesticide testing:
90 percent of fast-food brands contained at least trace levels of 27 different kinds of harmful pesticides.
Domino's and Pizza Hut pizzas were found to have the highest levels of pesticides.
Chipotle, In-N-Out and Panera Bread all had either trace or detectable and concerning levels of pesticides.
According to a study published in the journal Toxicology Reports, chronic toxicity caused by long-duration exposure to pesticides to even low doses of oral consumption can become evident much later as chronic diseases, including asthma, cancer, congenital defects, dermatitis, endocrine disorders, immunotoxicity, neurobehavioral disorders and reproductive dysfunctions.
