Feb. 11, 2020 -- Check your freezer: Frozen smoothie kits sold nationwide are being recalled because they may be contaminated with listeria, according to the FDA.

The recall includes more than 29,000 cases of Blendtopia’s frozen Superfood Smoothie kits. Anyone who bought the brand’s “Glow,” “Detox,” “Energy,” “Immunity,” or “Strength” kits with best-by dates of July 2021, October 2021, and November 2021 should throw them away or return them for a refund.

The company says no other Blendtopia products are affected, and the issue is believed to be isolated to one ingredient provided by a supplier. According to the company's website, the products are sold in Whole Foods, Krogers, Wegmans, and other stores nationwide and were availabe for purchase on the company's website.

There are no confirmed reports of anyone getting sick from the smoothies, but anyone who is worried about a possible illness should call a doctor.

The CDC says Listeria monocytogenes can lead to a serious and sometimes deadly infection called listeriosis and is most likely to sicken pregnant women, newborns, elderly people, and people with weakened immune systems. For most people, it causes a mild fever and diarrhea.
