Where did I say it’s “no big deal?” It IS a big deal. It’s dishonest. It’s violating the show rules. In some states it may be prohibited.
But that’s different than saying it puts other horses at an appreciably different risk than anytime they go to a show with other horses.
It’s not the coggins TEST that knocked back EIA in the U.S. It’s the practice of euthanizing infected horses that knocked it back.
The test is only a snapshot in time. If a horse JUST got infected, the antibody levels may not be sufficiently high for a week or two. So you could test an infected horse, get a false “negative” and be out and about for a whole YEAR exposing other horses without knowing.
If you test a horse and he’s negative and then gets infected after the test, you could again be out and about exposing other horses.
Testing once a YEAR doesn’t do much except give an overall picture of the community as a whole. AND tell you that horse’s status on that day that the blood was tested. Not the next day. Or even possibly an accurate snapshot THAT day if the horse was recently infected.
EIA is spread by biting flies and other biting insects. Because of how wide the range of flies is, any farm within 3 miles of a farm with a case is considered exposed. A fly can go a mile in 30 minutes!
EIA is a very serious condition. But even horses who get yearly coggins aren’t “safe” if there’s ANY infection anywhere in the area. The coggins isn’t a vaccine. It doesn’t inoculate a horse. It’s just a antibody test.
Compare it to Zika (spread by, inter alia, mosquitos). Imagine you live in an area where it’s been found. You get a blood test today and come back negative. Would you then spend the whole year going to beaches and public places, feeling confident that you’re safe because you got tested 11.5 months ago? That’s what the coggins is, essentially.
