(CNN) – The CDC wants to say "no" to the dough from the cookie.
This season, you may find yourself preparing a series of delicious cookies in the kitchen.
But you may want to think twice before reaching the taste of this dough.
Flour and raw eggs can in particular contain bacteria and salmonella, respectively.
In 2016, the appearance of E. coli infections associated with crude flour, made 63 people sick.
"People may not be aware that flour is not treated for the destruction of bacteria, and there are epidemics of a particular type of E. coli associated with the ingestion of the crude batter," said Elerin, director of infectious diseases at the South Morning Bowl Hospital in Massachusetts .
So as you may want to use the taste, it's better for your health to wait until the treatments are fully cooked.
CDC has a full list of practices for handling safe food on its website.
