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.[2] 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.[3] Envigo is headquartered in Indianapolis, Indiana and employs more than 1,200 people at 30+ locations across North America, Europe and the Middle East.[4][failed verification]
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),[5] Indianapolis, IN, Livermore, CA, Boyertown and Denver, PA, St Louis, MO and others.[6][2] 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.[7] 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.[7]
History
Envigo was created in September 2015 when Huntingdon Life Sciences, Harlan Laboratories and three subsidiaries (GFA, NDA Analytics and LSR Associates) merged. The combined organization had 3,800 employees at inception with sales approaching $500 million.[8] The company's rebranded name, Envigo, supposedly incorporated the English words enhance, enrich and vigorous.[9] The Latin root of the word vigorous is “vita” meaning “life.”
The company consists of two core business units: Contract Research Services (CRS) and Research Models and Services (RMS). The CRS business unit offers a range of drug development and environmental sciences services, including safety assessment, analytical, metabolism, CMC and regulatory consultancy from nine contract research facilities located in Europe, the United States and Middle East. The RMS business unit provides research models (live animals), lab animal diets and bedding and support services from 30 sites worldwide.[10]
Envigo acquired LabCorp's Covance Research Products business in June 2019, while LabCorp's Covance Drug Development segment acquired Envigo's nonclinical contract research services business. Both companies continue to collaborate through a multi-year, renewable supply agreement.[11] In December 2019, Envigo acquired Horizon Discovery's research models business unit which provides genetically engineered models from its Boyertown, Pennsylvania and St. Louis, Missouri locations. The business unit uses gene editing expertise to produce customized models with clinically relevant gene deletions, insertions and other modifications which are then used as preclinical models for human disease during drug discovery and development. The two companies announced collaboration to ensure continuity and enable all customers to access CRISPR-edited research models for screening and other applications.[12]
Envigo RMS Holding Corp. was acquired by Inotiv in November 2021.[13] In July 2022, a shareholder filed a class action lawsuit against Inotiv for failing to disclose the effect the Envigo acquisition would have on Inotiv's earnings.[14]
Animal cruelty
Envigo owned and operated a research and breeding facility in Cumberland, Virginia that housed over 5,000 beagles, bred and sold for medical research. In 2019, PETA conducted an undercover investigation at Envigo's Cumberland facility. The investigation led to a PETA campaign calling for the USDA and other Envigo customers to cut ties with the company.[15] After a routine inspection in July 2021, USDA inspectors cited Envigo for 26 violations of the Animal Welfare Act.[16] Inspectors again cited Envigo for 13 violations, including 11 repeat violations, on a repeat inspection in October 2021.[17] Inspectors noted in their reports that more than 500 dogs were experiencing pain and discomfort, being left in 85-degree heat without air conditioning for up to five hours, and infrequent cleaning left kennels and feeders hounded by insects. More than a dozen dogs were found to have paw and eye injuries, as well as some with “severe dental disease.” In addition, the USDA noted that over a seven-month period, more than 300 puppies died from “unknown causes,” and the facility had kept unfinished records regarding their deaths.[18] As a result of these reports and undercover investigations by local news WRIC-TV and PETA, multiple state legislators in Virginia introduced new legislation that would tighten regulation and subject employees to criminal liability.[19][20][21]
After a repeat inspection on March 8, 2022, found five repeat violations, including unsafe conditions, animal injuries, and mold and feces in the food supply, Virginia Senators Mark Warner and Tim Kaine sent a letter to the USDA requesting that the facility's license be temporarily revoked. In a comment regarding the letter, Senator Warner said, "We’ve seen these horrific incidents … it needs to be shut down...Not only do we want the Cumberland facility to be closed on a temporary basis to make sure that we don’t see these violations, but we want to make sure there is a thorough review of Envigo’s facilities elsewhere around the country.”[22]
Suspension and Temporary Restraining Order
The U.S. Department of Justice filed a complaint against Envigo in federal district court on May 19, 2022, seeking an injunction to stop Envigo from breeding, selling, or otherwise dealing in beagles at its Cumberland, Virginia, facility. The complaint recited the long-term serious violations of federal law by Envigo and hundreds of deaths of animals at their hands, often occurring in brutal circumstances.[23] The government also seized nearly 150 beagles from the site that were in desperate need of medical treatment denied by Envigo.[24]
U.S. District Court Judge Norman Moon issued an emergency order imposing a series of restrictions on Envigo.[25] Judge Moon said the evidence from federal inspections of the Envigo puppy factory shows that more than 300 beagle puppies have died there over the last seven months of unknown causes. He also said in his order that nursing beagles were denied adequate food, and puppies were euthanized without anesthesia.[26]
“[T]he Government’s veterinarians continue to examine dogs throughout the weekend” there, and the number of dogs seized “is likely to grow,” according to the ruling. Beagles have been found with “significant and serious health conditions, including wounds … swollen or enflamed paws, or … dental disease” and “many more beagles still face inadequate food and water, veterinary care, and the other torturous conditions described.” This week, “investigators observed ‘widespread fighting’ between beagles sharing food sources ... [and] beagles fighting between adjacent cages.” According to the court, “In multiple enclosures, puppies were unable to access the spigots to get water on their own, and when the investigator ‘held down the spigot to release water,’ the puppies ‘immediately rushed to the spigot to get water and drank heavily and quickly.’"[26] Investigators also found numerous beagles trapped in cage floors, one whose jaw was stuck in the cage bars, and unhygienic conditions including insects, mold and a buildup of old food.[27]
“[T]he Government has provided sufficient evidence that Envigo is engaged in serious and ongoing violations of the Animal Welfare Act, and that an immediate temporary restraining order must issue to put a halt to such violations pending further proceedings,” Judge Moon wrote.[26]
In June 2024, Envigo resolved the two-year investigation by the Department of Justice by pleading guilty to conspiring to violate the Animal Welfare Act and conspiring to violate the Clean Water Act, agreeing to pay $22 million in fines, including the largest-ever fine imposed by the Department of Justice in an animal welfare case, as well as agreeing to pay an additional $13.5 million toward animal welfare and environmental projects, law enforcement expenses, and improvements to Envigo's facilities. Lawsuits and Federal investigations stemming from alleged illegal smuggling of monkeys from Cambodia, and misleading shareholders on the origins and sources of their primate research models (claiming all animals were purpose bred when in fact many were wild-caught), remain active.[28]
Settlement and the adoption of nearly 4,000 beagles
In a settlement reached in July 2022, Envigo agreed to no longer engage in activities at the Cumberland site that require an Animal Welfare Act license and to relinquish the nearly 4,000 beagles at the facility to the Humane Society of the United States.[7] The company was also ordered to pay a portion of the adoptions costs.[29] The remainder of the costs were covered by dog rescue charities.[30] This represents the largest animal welfare seizure in the Humane Society's 67-year history.[31] The Humane Society transported the dogs to a network of shelters across the United States and by September 1, 2022, all of the dogs had been adopted.[32] One of the beagles rescued from Envigo, a six-year-old female named Momma Mia, was adopted by Meghan, the Duchess of Sussex and Prince Harry.[33] Another rescued puppy named Morty was adopted by New Jersey Governor Phil Murphy and is now the First Dog of New Jersey.[34]
In June 2024, Envigo pleaded guilty to federal animal welfare and environmental crimes and agreed to pay $22 million in fines plus $13.5 million to support animal welfare and environmental projects, cover law enforcement expenses and improve its own facilities.[35]
