P.F. Chang's China Bistro Ltd. alerted customers and the public Monday that a data breach involving customers' credit and debit cards affected 33 locations in the U.S.

The company said the problem has been contained, and it has been securely processing credit and debit card data since June 11, a day after the U.S. Secret Service flagged a possible security problem. It hasn't been determined whether any specific customer's data was stolen.

The breach was first disclosed in June, as the investigation began with third-party forensics experts and the Secret Service.

A list of affected locations/dates and a statement from P.F. Chang's CEO Rick Federico, is available here.

The store at 3101 PGA Boulevard in Palm Beach Gardens is on the list (dates in question range from 2/21/2014 to 6/11/2014).

The other Florida stores were at 436 North Orlando Avenue in Winter Park and at 27001 US Highway 19 N, Ste #1150 in Clearwater.
