USDA Instituting New Blood Test for Equine Piroplasmosis

Horse Health Press Release


Effective February 1, 2004, the U. S. Department of Agriculture will institute a new blood test for determining the Equine Piroplasmosis (EP) status of horses upon entry into the U.S. The competitive enzyme-linked immunosorbent assay (CELISA) is more sensitive than the Complement Fixation test (CFT), which is currently used to test for EP. The CELISA has a greater chance of identifying chronically infected horses with piroplasmosis. Testing for EP is conducted on all horses imported into the U.S. with the exception of horses from Canada and Iceland.

USDA's National Veterinary Services Laboratory (NVSL) has spent two years validating the CELISA, which was developed by the USDA Agriculture Research Service.

As of January 1, 2004, USDA will perform, upon request, the CELISA on pre-entry sera from horses due to be shipped after February 1. Use of the pre-import test is recommended. Horses found to be positive for Piroplasmosis are not permitted entry into the U.S.

Questions can be directed to Dr. Freeda Isaac, APHIS, VS, National Center for Import and Export, 301-734-8364.
