Most people gauge the doneness of their hamburgers by the color of the meat.
But despite browning, E. coli could still be living in your burger.
According to the U.S. Department of Agriculture, “A consumer who believes a brown color always means a safe hamburger is taking a chance on foodborne illness.”
Hamburgers can brown before they reach 160 °F, which is the temperature needed to kill E. coli.
Ground beef can also remain pink above 160 °F depending on fat, pigment and PH levels.
Using a food thermometer is the only accurate way to confirm your burgers’ safety. The young and the elderly have the highest risk of complications, even death, from E. coli.
Take a look at these eight burgers to see the variations in color based on temperature.
