How Common is Salmonella in Raw Cookie Dough?

how common is salmonella in cookie dough?

Salmonella in cookie dough is relatively uncommon, but it can occur when the dough is made with unpasteurized eggs or raw flour, both of which can potentially be contaminated with bacteria.

Recently, the Centers for Disease Control and Prevention (CDC) has been investigating 18 cases of salmonella infections across six states, with some cases linked to Papa Murphy’s raw chocolate chip cookie dough and s’mores bars dough.

It is worth noting that not all cases may be reported or tested, so the actual number of cases may be higher.

Symptoms of salmonella typically appear within six hours to six days after consumption and may include diarrhea, fever, and stomach cramps.

Most people recover without medical treatment, but certain individuals with weakened immune systems or at a higher risk may require medical attention.

To reduce the risk of salmonella, it is advisable to dispose of any affected dough and consider alternatives made with heat-treated flour and pasteurized eggs.

Quick Tips and Facts:

1. Contrary to popular belief, the main culprit for Salmonella contamination in cookie dough is not the raw eggs, but rather the raw flour. Flour can become contaminated with Salmonella during the milling process, and if the dough is consumed without baking, the bacteria remain alive and can cause illness.

2. The first documented salmonella outbreak linked to cookie dough occurred in 2009, affecting numerous states in the United States. Over 70 people were infected, leading to a large-scale recall of cookie dough products from grocery stores and a subsequent investigation into the source of contamination.

3. In 2016, General Mills issued a voluntary recall of 10 million pounds of flour due to potential Salmonella contamination. Although the recall was primarily focused on flour, it highlighted the risk of using contaminated flour in homemade cookie dough, where the flour itself is often left uncooked.

4. It is estimated that approximately 1 in 20,000 eggs are contaminated with Salmonella, making the risk relatively low. However, the potential for contamination still exists, which is why health authorities recommend cooking or baking dough containing raw eggs to kill any bacteria present.

5. While most cases of Salmonella infection from cookie dough are mild and resolve on their own, some can lead to more severe complications, especially for vulnerable populations such as young children, elderly individuals, and those with weakened immune systems. Therefore, it is generally advised to avoid consuming raw cookie dough, no matter how tempting it may be.
