Disease resistance

All eggs shipped from Troutlodge are certified disease-free through an extensive, independent process that meets and exceeds OIE standards. Because of our global customer base, it is subject to a wide variety of health certification requirements, and so it has developed a comprehensive testing program that is unparalleled in the industry.

As part of our Fish Health Management Program, each group of fish is tested twice a year. All sampling is conducted by an independent veterinarian, accredited by the United States Department of Agriculture - Animal & Plant Health Inspection Service (USDA/APHIS). Collected samples are then shipped to the Washington Animal Disease Diagnostic Laboratory (WADDL) at the Washington State University School of Veterinary Medicine for analysis. Testing protocols of both the OIE Diagnostic Manual and the Fish Health Blue Book of the American Fisheries Society are utilized for pathogen analysis. WADDL is approved by the USDA for aquatic animal health testing.
