A biotech firm dug into what's really in hamburger meat, and made some stomach-turning finds.
The company Clear Labs performed genetic analysis on 258 samples of meat and veggie burgers. They looked at frozen products, fast food burgers, and patties from grocery stores.
Tests showed two cases of meat in vegetarian products, and one black bean burger that contained zero black beans.
Three of the samples had rat DNA in them.
But the issue that really got our attention: one of the samples contained human DNA, likely a piece of finger nail or skin that got mixed-in during the manufacturing process.
