After recalling several flavors of ice cream due to a listeria outbreak in a Blue Bell factory, the company has decided to close its Broken Arrow, Oklahoma facility until further notice.

“Quality and safety have always been our top priorities,” Blue Bell CEO and president Paul Kruse said in a statement. “We are deeply saddened and concerned for all those who have been affected [by the listeria outbreak].”

On March 13, Blue Bell Ice Cream decided to recall several single-serve flavors of ice cream due to their possible links to five cases, including three deaths, of the foodborne illness listeriosis in Kansas.

“Investigations to determine whether these illnesses are related to exposure to Blue Bell products is ongoing,” the Center of Disease Control (CDC) said in a statement about the recall. “[We advise to not consume] any Blue Bell Creameries product manufactured in the company’s Oklahoma facility.”

After this comment from the CDC was released, Blue Bell made the decision to close its factory located in Broken Arrow, Oklahoma so that it may be investigated by the CDC.

“Listeriosis is a life-threatening infection caused by eating food contaminated with the bacterium listeria monocytogenes,” the CDC said in a statement. “People at high risk for listeriosis include pregnant women, adults 65 and older, and people with weakened immune system.”

Blue Bell has stated that the Broken Arrow factory’s doors will remain closed until the cause of the listeria contamination is revealed in the investigation being coordinated alongside the CDC.

“I want to personally apologize for any anxiety or inconvenience caused by the recent recalls of certain Blue Bell products,” Blue Bell CEO and president Paul Kruse said in a statement. “While the recalls include a limited number of items, we know that this type of event creates concern for our consumers and our retail partners … who have come to trust us to provide quality ice cream products.”
