On June 20, 2012, a staff member at California Correctional Health Care Services (CCHCS) inadvertently emailed Social Security Numbers along with leave balance information to other staff members within California Department of Corrections and Rehabilitation institutions. CCHCS issued a recall request for the email but could not determine if recipients read it. Notices were sent on July 10, 2012. CCHCS stated it has taken steps to mitigate recurrence.
