The Center for Disease Control wants everyone to "say no to raw cookie dough" this holiday season.

"When you prepare homemade cookie dough, cake mixes, or even bread, you may be tempted to taste a bite before it is fully cooked," a CDC spokesperson said. "But steer clear of this temptation—eating or tasting unbaked products that are intended to be cooked, such as dough or batter, can make you sick."

The CDC said children can also get sick from handling or eating raw cookie dough that is used for crafts.

The flour used in raw cookie dough is typically a raw agricultural product which means it has not been treated for E.coli, so the germs aren't killed until the food made with the flour is cooked, the CDC spokesperson explained.

Two years ago, 63 people got sick from E.coli infections linked to raw flour.

The CDC also warned about the raw eggs used in cookie dough.

To keep you safe, the CDC put together a list of safe food handling practices to use when you are baking and cooking with four and other raw ingredients:

  • Do not taste or eat any raw dough or batter, whether for cookies, tortillas, pizza, biscuits, pancakes, or crafts made with raw flour, such as homemade play dough or holiday ornaments.
  • Do not let children play with or eat raw dough, including dough for crafts.
  • Bake or cook raw dough and batter, such as cookie dough and cake mix, before eating.
  • Follow the recipe or package directions for cooking or baking at the proper temperature and for the specified time.
  • Do not make milkshakes with products that contain raw flour, such as cake mix.
  • Do not use raw, homemade cookie dough in ice cream.
  • Cookie dough ice cream sold in stores contains dough that has been treated to kill harmful bacteria.
  • Keep raw foods such as flour or eggs separate from ready-to-eat foods. Because flour is a powder, it can spread easily.
  • Follow label directions to refrigerate products containing raw dough or eggs until they are cooked.
  • Clean up thoroughly after handling flour, eggs, or raw dough:
    • Wash your hands with running water and soap after handling flour, raw eggs, or any surfaces that they have touched.
    • Wash bowls, utensils, countertops, and other surfaces with warm, soapy water.
