Lab Locations

CAHFS is a livestock and avian diagnostic laboratory, not a small animal laboratory. Questions concerning dogs, cats, snakes, and fish should be directed to your local veterinarian.

The CAHFS Toxicology Section may be contacted regarding any poisoning cases in all animal species at this number: (530) 752-6322.

Each laboratory in the CAHFS System performs specific tests. If the CAHFS Lab nearest your location does not perform the test(s) needed for your submission, the specimen may be forwarded to the lab in the CAHFS System that does perform the test.

Business Hours:  Monday through Friday, 8 AM to 5 PM

Emergencies only on Saturday and Sunday.

Davis Laboratory

The Davis facility consists of two laboratory buildings: The John E. Thurman, Jr. Building, and the Kenneth L. Maddy building.  Davis is staffed and equipped to provide the full range of diagnostic procedures in the disciplines of pathology, bacteriology, mycology, serology, avian virology, mammalian virology and toxicology for all species of livestock including poultry.  It also houses the Equine Analytical Chemistry laboratory, which is staffed and equipped to provide equine drug testing.

The Davis laboratory also conducts tests on specimens forwarded from the other four laboratories, which have not been staffed and equipped to perform them. As the central laboratory of the CAHFS, it provides professional support and supervision of tests and procedures to be used throughout the CAHFS. Discipline specialists at Davis, working with diagnosticians at the other laboratories, develop standard protocols and provide standardized reagents for use in the CAHFS. They also have supervisory responsibility over activities of their specialty, including both monitoring of testing procedures and the training of personnel in the use of such procedures at the other laboratories.

The Davis Laboratory accepts AVIAN, LIVESTOCK, and HORSE submissions. Carcasses may be submitted for necropsy. Submissions for livestock and horse biopsies, serology, bacterial cultures and electron microscopy are also accepted. The Toxicology section of the Davis Lab will accept specimens from all animal species, including domestic animals, wildlife, and sea mammals.
