Schnuck Markets says more than two million customers in the St. Louis area may have been impacted by a data breach that stretched from December 2012 until March 29.
The company said in a statement today that the cyber-attack possibly affected 79 of its 100 stores. Officials emphasized that the hackers only accessed the credit card numbers and expirations dates of victims - not their names, addresses or any identifying information.
Many customers of the Schnucks grocery chain are upset about the credit card fraud that has victimized dozens of people. Investigators told the St. Louis Post-Dispatch that they continue to receive complaints from Schnucks customers.
It still isn't clear how the security breach occurred. For now, investigators are telling people who shop at Schnucks to pay with cash or checks.

The US Centers for Disease Control and Prevention has announced that romaine lettuce was the source of the E. coli outbreak that sickened a total of 60 people in ten states earlier this fall.
Thirty-seven of those infected were in Missouri.
On its website, the CDC says the lettuce came from salad bars from a single grocery store chain but did not report the name of the chain. Schnucks management has confirmed that it is the chain in question.
