CORRECTING MISINFORMATION ABOUT MARSHALL BIORESOURCES

Does Marshall BioResources conduct research on animals?

Marshall BioResources does not conduct any pharmaceutical or medical device testing with its animals, including discovery- or safety-related studies.

Marshall does not perform vivisections. It does not conduct any pharmaceutical or medical device research, including discovery- or safety-related studies.

Marshall BioResources’ animal care practices are designed to promote health and safety. Enclosures are designed to provide space for exercise, behavioral enrichment, and positive social interaction among animals. Trained caregivers interact with the animals each day through gentle handling and observation. Kennels are spot cleaned daily and completely sanitized biweekly to help maintain a healthy environment. Animal health and welfare are routinely monitored by trained animal care professionals and on-site veterinary staff.

Marshall BioResources provides humane and ethical care for its animals. Its work improves the health and welfare of hundreds of millions of pets and companion animals worldwide that depend on animal-based clinical tests undertaken by its customers. These ensure the safety and efficacy of advancements such as flea, tick, and heartworm preventives, vaccines that protect pets from deadly disease, arthritis and pain medications for pets, and cancer therapies for dogs and cats.

The size of Marshall BioResources’ animal enclosures, compatible grouping, exercise requirements, feeding, watering, and cleaning and sanitizing are strictly regulated by the USDA in Animal Welfare Regulations sections 3.6-3.11 (see https://www.aphis.usda.gov/sites/default/files/ac_bluebook_awa_508_comp_version.pdf).

Marshall BioResources’ facilities are regularly inspected by the U.S. Department of Agriculture (USDA) to ensure compliance with federal animal welfare standards. Its most recent unannounced USDA inspections were conducted in May 2026 and July 2026, both resulting in clean reports with no citations. Marshall BioResources also maintains voluntary accreditation through AAALAC International, an independent nonprofit organization that promotes high standards often stricter than federal law. In addition, its programs have earned ISO 9001 certification for quality management and operational standards.

Not at this time. In some narrow domains, NAMs (non-animal models) are now accepted instead of traditional animal-based tests. These include specific types of skin sensitization, skin corrosion, and eye irritation, with progress in areas such as liver toxicology. However, they cannot yet replicate complex pharmacokinetic, immunology, or multi-organ interactions—all critical factors to ensure the safety of drugs and devices.

That claim lacks important context. In modern biomedical research, animals continue to play a pivotal role in the responsible development of treatments, especially to establish safety prior to moving to testing in humans. That is essential and needs to be considered separately from efficacy analysis.

This is purposely misleading disinformation spread by activists. They conflate later-stage human efficacy studies with preclinical drug development safety studies, in which critical animal research identifies 71% of toxicities later observed in humans (https://www.sciencedirect.com/science/article/abs/pii/S0273230000913990).

Abruptly eliminating carefully regulated animal research would slow medical progress, delay the development of future therapies, and impact advances that benefit both humans and animals alike.

The FDA Modernization Act 2.0 does not directly eliminate, ban, or reduce animal research or “allow” the FDA to consider non-animal research data in a way they couldn’t before. Instead, it formally codifies that non-animal research data can be considered in submissions on efficacy and safety.

Dogs have similar anatomical and physiological traits to humans, particularly with respiratory, cardiovascular, and musculoskeletal systems.

Marshall BioResources’ goal is to match the needs of the research community with the number of animals it raises. In the rare instances when that does not happen, we first look to offer animals for adoption. MBR is expanding efforts to help rehome some animals through partnerships with existing adoption organizations, including Homes for Animal Heroes. In addition, it has formed a nonprofit organization and is pursuing licensing to establish a dedicated adoption and rehoming facility under New York State law.

This is a deceptive activist talking point, meant to spread dangerous disinformation. We provide humane, ethical care for our animals, winning the respect of medical and healthcare communities worldwide.

This is a false claim. Dogs may need to wear masks for mandatory safety and efficacy studies on life-saving inhaled medications, like those used to treat asthma and other respiratory conditions. Screenings to determine which dogs are right for this type of research are now conducted by our clients at their facilities, not at MBR.

The animals in Marshall BioResources’ care are raised in environments similar to what they will experience after being placed with customers in medical and scientific sites; this reduces their stress levels and promotes their friendly demeanor. This includes indoor socialization with people and other animals, toys for enrichment and play, and veterinary care.

The extremely limited instances of reports from former contractors and employees have been proven to be untrue, and are the product of activists looking to spread disinformation. Marshall BioResources provides humane and ethical care for its animals. Its most recent unannounced USDA inspections were conducted in May 2026 and July 2026, both resulting in clean reports with no citations.

Animals raised by Marshall BioResources experience regular indoor socialization with people and other animals, toys for enrichment and play, and veterinary care.

The animals in Marshall BioResources’ care are regularly examined by veterinary staff to assess their overall health, including laboratory and physical tests similar to or in some cases more extensive to how a family pet may be examined. Veterinary care requirements are described and enforced by the USDA under Animal Welfare Regulations section 3.13.

Marshall BioResources employes more that 200 people in its North Rose, N.Y. operations, including veterinary staff.

Marshall BioResources has never been affiliated with Ridglan Farms or Envigo. For more than 85 years, we have earned the trust of the medical and healthcare communities by upholding high standards across all aspects of our work.

No. We cannot speak to how other companies chose to conduct business. Marshall BioResources has been a leader in the field for more than 85 years because of how it operates. MBR treats employees well and provides humane, ethical care for its animals, winning the respect of medical and healthcare communities worldwide.

The health and welfare of hundreds of millions of pets and companion animals worldwide depend on animal-based clinical tests, ensuring the safety and efficacy of advancements such as flea, tick, and heartworm preventives, vaccines that protect pets from deadly disease, arthritis and pain medications for pets, and cancer therapies for dogs and cats.

Marshall BioResources has long been part of the fabric of the local community. In addition to supporting medical and veterinary research, the company and its foundation invest in programs and partnerships that strengthen the region and improve quality of life for local residents, as well as providing more than 200 jobs with comprehensive benefits.

Open rescue is a deceptive term for unlawful trespass, entry into private facilities and animal theft, which have resulted in serious charges, including felonies. Activists planning this type of event are intentionally downplaying the risks of physical confrontation with law enforcement, with the potential for injury or even death. Open rescue is not heroic; it is a crime.

Representative Nick Langworthy is associating himself with activists facing serious felony charges including burglary, theft, and criminal damage to property. He is directly responsible for spreading disinformation that endangers the health and safety of his constituents and their pets. Claims that animal research is no longer necessary overlook important scientific and regulatory realities and disregard the expertise of the scientific and medical communities.

Calls to eliminate animal testing in the U.S. puts the country and Americans at a disadvantage, as this research will move overseas to the detriment of U.S. biomedical leadership, advanced pharmaceutical and medical device development, U.S. employment and the health of U.S. citizens.
