Envigo

Envigo (en-VEE-go) is a privately held contract research organization and laboratory animal sourcer that provides live animals and related products and services to pharmaceutical and biotechnology industries, government, academia and other life science organizations engaged in animal testing. The company breeds and sells research animals – which are referred to in the industry as "research models"– including rodents (mice, rats, hamsters and guinea pigs), rabbits, beagles and non-human primates. Envigo is headquartered in Indianapolis, Indiana and employs more than 1,200 people at 30+ locations across North America, Europe and the Middle East.

Many of Envigo's breeding sites have been accredited by the Association for Assessment and Accreditation of Laboratory Animal Care (AAALAC) International Council including: Horst, the Netherlands (March 29, 2016), Indianapolis, IN, Livermore, CA, Boyertown and Denver, PA, St Louis, MO and others. However, the U.S. Department of Agriculture (USDA) found multiple violations of the Animal Welfare Act at the company's Cumberland, Virginia dog-breeding facility and the U.S. Department of Justice filed a complaint against Envigo for the violations in federal court. In a settlement reached in July 2022, the company agreed to no longer engage in activities at the site that require an Animal Welfare Act license and to relinquish the over 4,000 beagles at the facility to the Humane Society of the United States.
