A local grocery store chain has reported a data breach involving locations in five states including Illinois and Missouri.  Supervalu, the parent company of Shop 'N Save, reports the breach of customer information took place between June 22 and July 17, and impacted stores in Alton, East Alton, Jerseyville, Wood River, and the Shop 'N Save Pharmacy location in Bethalto.

A company statement indicates the breach was discovered and they believe it was contained and it's unknown if any customer information was stolen.  In 2012, the Schnuck's chain experienced a similar data breach and recently settled with customers that were affected.  Supervalu will open a customer service number on Monday morning at 855-731-6018, or you can visit www.supervalu.com. You can go to your local store for details if you feel your account was compromised.
