If you used your credit card at a Whole Foods restaurant or taproom in the Bay Area recently, then you should keep an eye on your recent transactions, as a data breach may have revealed your financial info to hackers.

According to a CBS report on the hack, the data breach only involved point of sale systems at the restaurants and taprooms that are located inside Whole Foods stores. In the Bay Area, this means that there are nine locations that were affected, including:

  • Cupertino, Stevens Creek Boulevard
  • Dublin, Dublin Boulevard
  • Mill Valley, East Blithedale
  • San Francisco, Rhode Island Street
  • San Francisco, 4th Street
  • San Jose, The Alameda
  • Santa Clara, Augustine Drive
  • Walnut Creek, Ygnacio Valley Road

ABC 7 shared a lookup tool created by Whole Foods that names the cafés, restaurants, and other businesses where these breaches occurred. If you shopped at any of the above locations and the smaller businesses therein, then you should double check to make sure your card statement is in order.

Whole Foods acknowledged the breach in a statement, saying that their investigation into the whys and wherefores of the hack is still ongoing. Though they don't believe the point of sale systems in the grocery stores themselves were compromised, they still say customers should "closely monitor their payment card statements and report any unauthorized charges to the issuing bank." The company has yet to reveal just how many customers were affected by the breach.
