Some Whole Foods customers may have had their credit card information stolen after the company stated Thursday it had been tipped about "unauthorized access of payment card information," Consumerist reports. The data breach would only affect cards used at the taprooms and full-service restaurants at some Whole Foods locations. Customers who just bought groceries should be fine. Gizmodo notes there's a lot we don't know about the breach, including how many stores it affected, the locations of those stores, how many customers were affected, how long the breach lasted, and how long Whole Foods knew about the breach before going public. "Whole Foods needs to tell the whole truth about this incident, and soon,” says Rep. Diana DeGette, the top Democrat on the House subcommittee on oversight and investigations. (Recent customers at Sonic may have also had their credit card information stolen.)
