Jeni’s Splendid Ice Creams is recalling all its ice cream, frozen yogurt and sorbet after a sample tested positive for the deadly bacteria Listeria.

Once the contamination was discovered in a randomly selected pint of Jeni’s ice cream, the company “made the swift decision to cease all ice cream production and sales” until “all products are ensured to be 100% safe,” the company announced on its website Thursday.

“We have called in experts to help us find the root cause. We will be working with our suppliers to determine if the bacteria was introduced by one of the ingredients we use. We will not reopen the kitchen until we can ensure the safety of our customers,” a statement from Jeni’s CEO John Lowe reads.

The company is not aware of anyone getting sick from the contamination, but the recall announcement comes in the wake of an expanded recall of Blue Bell Ice Cream products, which have been linked to three Listeria-related deaths and several illnesses. The Centers for Disease Control and Prevention said the Blue Bell Listeria case dates back to 2010.

Listeria causes nausea, headaches, abdominal pain and diarrhea in healthy people. Listeria can be fatal to the very young, very old, and those with weak immune systems. It can also cause pregnant women to miscarry.
