The CDC keeps warning people not to eat raw cookie dough — even though it's delicious

The Washington Post

The Christmas cookies are in the oven; the mixing bowl, which is still coated with the sugary sweet dough, is calling your name.

Don't listen to it, health experts warn.

With holiday baking season underway, the Centers for Disease Control and Prevention is once again urging people not to eat unbaked cookie dough - not even a tiny taste - because "unbaked products that are intended to be cooked, such as dough or batter, can make you sick."

"Say No to Raw Dough!" the CDC warns.

The potential problem is with two primary ingredients.

Raw flour can be contaminated with Escherichia coli (E. coli), and raw eggs have been a known carrier of salmonella bacteria.

Both bacteria are killed in the cooking process, but contaminated food that is not cooked or is undercooked has been known to make people ill, according to the CDC.

"When you're making cookies, often the recipe calls for raw eggs," Lindsay Malone, a registered dietitian with the Cleveland Clinic, said in 2016. "Whenever you consume raw eggs, you increase your risk of salmonella poisoning." Malone added that "when there's a risk for salmonella, you really want to be cautious and take steps to avoid it as much as possible."

In recent years, public health experts have become vocal about raw flour, too.

The CDC reported that in 2016, more than 60 people across the United States were sickened with E. coli from raw flour.

According to an alert from the U.S. Food and Drug Administration:

That means no taste-testing batter or dough - not for cookies, cakes, pies or even bread and pizza crust.

In addition, the CDC said, children should not be permitted to play with dough because they can get sick simply from handling it.

The health agency sounds the alarm about eating raw cookie dough every year around this time, and the U.S. Department of Agriculture's Food Safety and Inspection typically echoes the CDC.

However, not all public health experts agree that raw cookie dough is dangerous.

Brian Zikmund-Fisher, associate professor of Health Behavior and Health Education at University of Michigan, wrote in the Conversation in 2016 that his family eats raw cookie dough "regularly."

"To start, when most people think about health risks and cookie dough, they think about raw egg. Eggs can be contaminated with salmonella bacteria, and food safety recommendations encourage people to cook eggs until the white and yolk are firm in order to kill any bacteria," Zikmund-Fisher wrote. "Because of this concern, when my kids and I make cookie dough, we never use regular eggs. Instead, we use eggs that have been pasteurized to kill any harmful bacteria without actually cooking the egg itself. (A great public health innovation, if you ask me!) So, I wasn't worried about the eggs in the cookie dough."

On raw flour, he said that contamination is "rare."

Symptoms from E. coli infection typically appear within several days and may include severe stomach pain, diarrhea and vomiting; symptoms of a salmonella infection are similar but may also include a fever, according to the CDC. With both illnesses, patients usually recover within less than a week, according to the agency.

To avoid potential infection, the CDC suggests not eating raw cookie dough or cake batter, of course, but also not making homemade ice cream or milkshakes with the uncooked ingredients. (However, according to the FDA, commercial cookie dough ice cream is typically safe because it is made with treated flour and pasteurized eggs.) The CDC also urges people to thoroughly wash their hands with warm, soapy water and to clean all work surfaces, dishes and utensils when working with raw eggs and flour.
