This may churn the stomachs of hamburger lovers. A new study shows burgers are contaminated with various things, including parts of humans and even rats.
Clear Labs tested 258 burgers from undisclosed retailers and fast food chains in northern California. Tests showed rat DNA in three burgers and human DNA in a frozen vegetarian burger.
The good news is cooking the burgers will kill the rat and human DNA cells and then they can't make you sick.
Clear Labs said it wants to work with the food industry to improve contamination problems.
