Humane Care

At CRADL™, staff are on-site seven days a week to assess the animals under their care. Along with observing the health of animals, staff ensure they have access to food, water, and a clean cage. Depending on the species of an animal, cage changes occur on a weekly or bi-weekly basis and are performed at a dedicated animal transfer station or biosafety cabinet. Standard disinfection protocols are followed for cleaning stations and countertops, as well as for receiving delivered supplies and animal orders. An animal welfare specialist and clinical veterinarian have direct responsibility for all animal welfare concerns.  

At Charles River we strive to BE THE DIFFERENCE. One of our core company values is CARE. We believe that great animal welfare makes for the best translational science. We ensure a safe and healthy environment for all our clients and the animals living in our facilities. We are committed to the ethical use and humane treatment of animals in research. Charles River’s Humane Care Imperative is overseen by our Animal Welfare and Training group. They ensure that all our facilities comply with the stringent standards of practice and accepted guidance for the care and use of laboratory animals.

CRADL is led by a Diplomate of the American College of Laboratory Animal Medicine (ACLAM) along with a team of experienced attending veterinarians at each location with a variety of backgrounds in industry and academia to ensure compliance with all federal, state and local regulations. Every study conducted in our facilities and with our services is required to be approved by a Charles River Institutional Animal Care & Use Committee (IACUC). Charles River strongly advocates for the replacement, reduction, and refinement (3Rs) of animal use in research.

In all Charles River CRADL facilities we offer animal care & compliance services in support of your in vivo science. Our welfare services are INCLUDED in your partnership with us in alignment with our shared values:

Biosecurity is comprised of several elements, ranging from entry of animals into the facility, control, and disinfection of materials that come into contact with animals, and management of human-animal contact. The ultimate goal of the CRADL™ biosecurity program is to reduce or eliminate the potential of introducing an adventitious agent into your animal colonies. This comprehensive program incorporates the latest methodology and protocols to ensure constant management over the critical control points that are seen as areas which pose the highest risk to a facility.
