Covance & the Cumberland Facility
The corporate chain behind the Cumberland, Virginia beagle breeding facility — from Hazleton Laboratories in the 1960s through Covance through Envigo through Inotiv. A single facility that changed hands four times, accumulated decades of violations, and ultimately produced the largest AWA penalty in history.
The beagle breeding facility in Cumberland County, Virginia that became infamous under the Envigo name had been in continuous operation since the 1960s — changing corporate hands four times while breeding dogs on the same site for over five decades.
The Corporate Chain
| Period | Owner | Name | Notes |
|---|---|---|---|
| 1960s–1990 | Hazleton | Hazleton Laboratories / Hazleton Research Products | Founded the facility. Conducted tobacco research on tracheostomized beagles. |
| 1990–1996 | Corning | Corning Lab Services | Acquired Hazleton. Brief ownership. |
| 1996–2019 | Covance | Covance Laboratories | Major CRO era. One of top 3 US beagle breeders. |
| 2019–2021 | Envigo | Envigo RMS LLC | Took over Covance's research models operations. |
| 2021–2023 | Inotiv | Inotiv, Inc. (via Envigo acquisition) | Acquired November 2021. Closed under federal enforcement. |
The Hazleton Era (1960s–1990)
Hazleton Laboratories was a contract research company associated with the Council for Tobacco Research. Under the name Hazleton, the Cumberland facility conducted animal testing for tobacco companies.
Between February 1978 and March 1980, Hazleton conducted a two-year study for the National Cancer Institute (NCI) on the cardiovascular effects of mainstream cigarette smoke and carbon monoxide on 204 permanently tracheostomized male beagles.1 The dogs had tubes surgically inserted into their windpipes to force-inhale cigarette smoke — a procedure that first required devocalization.
This places the Cumberland facility in the direct lineage of the smoking beagles era of animal research.
The Covance Era (1996–2019)
Under Covance, the Cumberland facility became one of the top three US beagle breeding operations, alongside Marshall BioResources and Ridglan Farms.
Covance — which started in the basement of a former Seattle supermarket as Hazleton — grew into a transnational drug development corporation. By 2013, Covance's Madison, Wisconsin branch had 3,953 dogs according to its USDA annual report.2
Covance amassed 42 violations between its Pennsylvania and Virginia laboratories, including starving dogs and failure to provide veterinary care for broken bones.3
In 2015, Labcorp acquired Covance for $6.1 billion. The company was later restructured, with the research models operations at Cumberland transferring to Envigo in 2019.
The Envigo/Inotiv Era (2019–2023)
When Inotiv acquired Envigo in November 2021, it inherited a facility that had been breeding beagles on the same site for approximately 55 years. Within months, USDA inspections documented 70+ AWA violations, and the facility's decades of operation ended in a $35 million penalty and permanent closure.
Significance
The Cumberland facility's history illustrates how laboratory animal breeding operations can persist for decades under successive corporate owners, with each acquisition providing a fresh corporate identity while the underlying practices continue. The violations that ultimately destroyed Envigo/Inotiv had been incubating through multiple ownership changes over more than half a century.
