(Scroll down for video) Consumers are freaking out after a new report shows that some beef burgers contain rat or human DNA.
According to The Hamburger Report by Clear Labs, burgers contain pathogenic DNA, rat DNA and even human DNA.
The lab tested 79 brands of burgers from 22 retailers in California, and made some gruesome discoveries. The company found DNA of a rat in a fast-food burger, and a vegetarian burger contained beef.
The company also found human DNA in a frozen vegetarian burger, probably from hair, skin or nail that was mixed during the manufacturing process.
The lab said that while the findings are disturbing, the presence of human DNA or rat DNA is not likely to be harmful to humans.
According to the FDA, a low amount of rat DNA falls within the acceptable range. The study analyzed ground beef, frozen hamburgers, fast food burgers and vegetarian burgers.
The company claims that the results were not influenced by outside partners, companies, customers or other entities.
According to the study, fast food restaurants showed low levels of contamination. 23.6 percent of vegetarian products showed some sort of discrepancy between the product and the label.
