Last month, Jeni's Ice Creams voluntarily recalled all of their products and closed down scoop shops due to listeria being discovered in some of their pints.
Last week, the company announced that they have discovered the cause of the outbreak — a contaminated pint-filling machine in their Ohio facility.

The company lost an estimated $2.5 million worth of product when the outbreak was discovered.
