Veggie Noodle Co. of Austin, Texas is voluntarily recalling its Butternut Spirals because of possible contamination with Listeria monocytogenes.

The freshcut vegetable company distributed the spiral cut butternut squash to Whole Foods Markets and other retailers in Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Nebraska, Ohio and Wisconsin.

“The potential contamination of the Butternut Spirals was found as a result of routine product testing, according to the recall notice posted Wednesday on the Food and Drug Administration’s website. “There are no reported illnesses associated with this recall to date.”

However, it can take up to 70 days after exposure for symptoms of Listeria infection to develop. Anyone who has consumed any of the recalled product should monitor themselves for symptoms. If they become sick, they should seek medical attention and tell their doctors about the possible exposure to the bacteria.

Symptoms can include high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea. Otherwise healthy people can recover with little impact, but children, the elderly, pregnant women and people with compromised immune systems can develop serious infections that sometimes result in death.

“Consumers who have purchased the recalled Veggie Noodle Co. Butternut Spirals are urged not to consume it, and either discard the product or return it to the store wher it was purchased for a full refund.”

To determine whether they have the recalled product in their homes, consumers should look for the following codes on the 10.7-ounce clear plastic containers of spiral-cut butternut squash:

UPC number 852287006059; and

“Enjoy By” date of February 23, 2017, located on the side of the packaging.
