PORTLAND, Maine — Hannaford Bros. Company, the grocery store chain which has suffered the most recent major card security compromise has a credit union. The Hannaford Federal Credit Union serves the employees of the Hannaford Bros. Company and its affiliates and has since 1936.

The Maine based firm announced to the public that it had roughly 4.2 million card accounts compromised in the breach, which the company has maintained took place even though it had been audited as compliant with the industry's card security protocols.

The $27 million credit union has Hannaford and its affiliates as it sole sponsor and has roughly 7,400 members, or about 25% of the company's workforce, according NCUA records and Peter Prinz, CEO of the credit union.

Prinz reported that while the CU has the company's name and rents space from the firm, it is a completely separate institution. He said he learned the same day as the general public that the company had suffered a card breach, and then only a few minutes before the press release was sent out. “I didn't even have time to call any friends and family and let them know they had found a problem,” Prinz said.

The CU has a combined debit and credit portfolio of roughly 3500 cards but, so far, has only had one come through with any possible fraud, Prinz reported, but he added the CU is continuing to monitor accounts.
