The Minnesota-based retailer, which owns Shoppers and other U.S. supermarket chains such as Farm Fresh and Shop 'n Save, alerted customers it had a breach in the computer network that processes payment cards at some of its stores. Account numbers, expiration dates and/or cardholders' names could have been stolen, although the company has not determined whether any thefts occurred.
Data could have been stolen between June 22 through July 17 at 180 Supervalu-owned stores and 29 franchised Cub Foods stores and stand-alone liquor stores, listed here. The system intrusion did not affect Save-A-Lot stores.
The company is investigating but said customers can safely use credit and debit cards in its stores.
The grocer is offering customers who might have been affected 12 months of complimentary consumer identity protection services through AllClear ID and has set up a call center at (855) 731-6018.
