Traci Tamiko Eto, Mayo Clinic’s former director of research operations and AI compliance lead, filed a whistleblower lawsuit on July 6, 2026 alleging the health system concealed a 67% error rate in its MAYA AI-integrated digital assistant and put unapproved software into live clinical workflows. The suit, backed by ten other whistleblower reports, claims staff deleted unflattering test results and mischaracterized the tool’s capabilities before Eto was placed on a corrective action plan and terminated while on medical leave.
