Texas Administrative Code › Title 4 - AGRICULTURE › Part 2 - TEXAS ANIMAL HEALTH COMMISSION › Chapter 49 - EQUINE › Section 49.1 - Equine Infectious Anemia (EIA): Identification and Handling of Infected Equine

Current through Reg. 49, No. 28; July 12,
				2024
(a) Official Test.
				The agar gel immunodiffusion (AGID) test, also known as the Coggins test, the
				Competitive Enzyme-Linked Immunosorbent Assay (CELISA) test, and other USDA
				licensed tests approved by the commission, are the official tests for equine
				infectious anemia (EIA) in horses, asses, mules, ponies, zebras and any other
				equine in Texas.
(b) Authorization
				to conduct test. Only United States Department of Agriculture (USDA) approved
				laboratories, including USDA approved off-site laboratories, are allowed to run
				the AGID and CELISA or other USDA licensed tests and all tests will be
				official. Only test samples from accredited veterinarians or other TAHC
				authorized personnel accompanied by a completed VS Form 10-11 can be accepted
				for official testing.
(c) Official
				Identification of Equine Tested for EIA. All official blood tests must be
				accompanied by a completed VS Form 10-11 (Equine Infectious Anemia Laboratory
				Test) listing the description of the equine to include the following: age,
				breed, color, sex, animal's name, and all distinctive markings (i.e., color
				patterns, brands, tattoos, scars, or blemishes) and unique and permanent forms
				of identification, such as electronic identification that complies with ISO
				11784/11785; or non-ISO electronic identification injected in the equine on or
				before March 11, 2014; or digital photographs sufficient to identify the
				individual equine. In the absence of any distinctive color markings or any form
				of visible permanent identification (brands, tattoos or scars), the animal must
				be identified by indicating the location of all hair whorls, vortices or
				cowlicks with an "X" on the illustration provided on the VS Form 10-11. It must
				list owner's name, address, the animal's home premise and county, the name and
				address of the authorized individual collecting the test sample, and laboratory
				and individual conducting the test. The EIA test document shall list one horse
				only.
(d) Reactor. A reactor is any
				equine which discloses a positive reaction to the official test. The individual
				collecting the test sample must notify the animal's owner of the quarantine
				within 48 hours after receiving the results.
(e) Retest of reactors. Equine which have
				been disclosed as reactors may be retested prior to branding provided:
(1) owners or their agents initiate a request
				to the TAHC Area Director of the area where the horse is located;
(2) retests are conducted within 30 days
				after the date of the original test;
(3) blood samples for retests are collected
				by the person who collected the sample for the first test or by TAHC personnel,
				and the blood samples are submitted to the Texas Veterinary Medical Diagnostic
				Laboratory (TVMDL) for testing;
(4)
				the individual collecting the retest sample is provided documentation that the
				animal being retested is the same as the one shown positive on the initial test
				and can verify the retested equine as being the same as shown on the original
				test document; and
(5) the positive
				animal is held under quarantine along with all other equine on the
				premise.
