Whole Foods Looks into Payment Breach at Restaurants, Taprooms

The grocery chain Whole Foods acknowledged Thursday it’s investigating how payment cards used at some of its restaurants and taprooms may have been breached.

The company’s brief statement said the incident didn’t affect stores’ primary checkout system, but it is looking into the secondary point-of-sale systems used at locations that have table-service restaurants and taprooms. It also said the incident doesn’t affect Amazon.com systems, which it was recently purchased by.

The company didn’t disclose the number of people potentially affected but encouraged customers to monitor their card statements for unauthorized charges.

Whole Foods is working with cybersecurity forensics firms and law enforcement.
