The musical phrase " you are what you feed " is dead more actual for some than it has ever been . According to a Clear Labs genetic and nutritionary analysis bailiwick , latterly shared byGizmodo , some burger contain traces of ingredients that are not on the menu , include pathogens as well as rat and human DNA .

Forthe study , the researchers analyzed 258 burger sample distribution collected from 79 brands and 22 retail merchant in northerly California . They used next - generation sequence and other tests to determine authenticity , search for contaminants and allergens , and to determine if advertised factor were present in ground meat , veggie patties , frozen patty , and fast food product .

In improver to finding one disastrous dome Warren Burger with no black beans , Clear Labs ascertain meat in veggie burgers ; beef DNA in lamb , chicken , and bison burgers ; and pork , turkey , and chicken DNA in beef samples . It also detected rat DNA in a degraded food burger , beef sample distribution , and veggie Warren Earl Burger , and human DNA in a frozen veggie burger .

" While unpleasant , the presence of human DNA or rat DNA is not likely to be harmful for human wellness , " the authors write . They ’re likely the   result of inadequate food treatment practice .

Moreover , as the report notes , " What many consumers do n’t know is that some amount of human and rat DNA may fall within an satisfactory regulatory range . The amounts we notice in our research most in all likelihood settle within the acceptable regulative range as we understand them . "

Of the sample tested , about 4 percent ( 11 of the 258 ) were found to include pathogenic DNA that could lead to food for thought poisoning . However , the researchers monish that they could not determine whether the pathogens were idle or alive , issuing a admonition to consumers that the well elbow room to protect against illness is to manage and prepare food properly .

The lab also states that the purpose of the subject area is not to make consumers swear off all hamburger , but to " help the food manufacture future - proof their provision chains , reduce the risk of dearly-won recalls , and mostly improve quality of safety and quality by name out all observable trend and sixth sense at the molecular horizontal surface , regardless of whether or not they are satisfactory fit in to FDA guideline .
