An estimated 100,000 cases of Weight Watchers Smart Ones Chocolate Chip Cookie Dough Sundae frozen desserts have been recalled following a possible Listeria monocytogenes contamination, the United States Food and Drug Administration announced Monday.

The list of recalled items includes packages with 21 UPC codes and a variety of “best if used by” dates ranging from Dec. 28 to July 28, 2017.

Customers can get a full refund by returning the product to the place they bought it, where they also have the option to exchange the treat. Those who do not wish to go back to the store can also get a full refund by calling 866-572-3805 between 9 a.m. and 6 p.m. EST Monday through Friday.

The recall of the Weight Watchers Smart Ones Chocolate Chip Cookie Dough Sundae frozen desserts took place after the supplier of the cookie dough, Aspen Hills, Inc. announced positive test results for Listeria monocytogenes. Following an investigation by Weight Watchers, the company chose to voluntarily pull items from shelves out of precaution, according to the FDA.

Listeria monocytogenes is classified as a significant public safety problem in the U.S. and affects adults with weak immune systems, pregnant women, the elderly and newborns, according to the Centers for Disease Control and Prevention.

Infected pregnant women can experience premature delivery, miscarriage or stillbirth. Their newborns' lives can also be at risk. People who are not with child can have a variety of symptoms, including fever, muscle aches, stiff neck and headaches. The elderly are at risk of meningitis and septicemia, according to the CDC.

Despite the U.S. product recall, there have been no customer reports of sickness related to the possible Listeria monocytogenes contamination.

This is not the first time a company has recalled their products following the use of cookie dough from Aspen Hills, Food Safety News reported. Businesses like Blue Bunny , Blue Bell Creameries, Nutrisystem and several others were forced to pull products from stores earlier this year due to possible listeria contamination.
