Food analytics platform Clear Labs identified problems with ingredient substitutions, hygiene, and contamination in 13.6% of the 258 burger products the company analyzed on a molecular level, in a report released on Tuesday. The company analyzed ground meat, frozen patties, fast-food burger products, and veggie burger products.
Some of the most jarring numbers: 4.3% of samples contained traces of pathogenic DNA, rat DNA was found in three products, and human DNA was discovered in one frozen vegetarian burger.
