The Ridglan Investigation
The Ridglan investigation spans from Wayne Hsiung's 2017 undercover footage through six years of prosecutorial inaction, a court-ordered special prosecutor in January 2025, 311 DATCP violations, a settlement requiring license surrender, and a March 2026 rescue operation. The case exposed systemic failures in both USDA inspection and local prosecution.
Overview
The Ridglan investigation is a case study in the distance between documented animal welfare violations and meaningful enforcement. It began with undercover footage in 2017 and required eight years, multiple legal interventions, and sustained public pressure before producing consequences for Ridglan Farms.

The Prosecution Gap
Six years elapsed between the initial investigation and any prosecutorial action. The Dane County DA's office received multiple contacts — formal complaints, follow-up letters, and in-person meetings — without initiating a case. The revelation of 983 emails between the DA's office and parties connected to Ridglan raised questions about the nature of the delay.
The Special Prosecutor
The court's January 2025 order appointing a special prosecutor was a rare judicial intervention. Tim Gruenke, a former Dane County prosecutor, was appointed in February 2025. Within months, DATCP assessed 311 violations — primarily for unlicensed veterinary procedures — and a $55,000 fine. Veterinarian Scott Gilbertson and facility operator Matthew Reich were named in enforcement actions.
Significance
The Ridglan investigation demonstrates that the regulatory framework can fail at every level simultaneously: USDA inspection, state agricultural oversight, and local prosecution. Enforcement ultimately required external legal pressure and judicial intervention rather than the routine functioning of any single regulatory body.
