EIA is a viral disease characterized by a hemolytic anemia, depression,intermittent fever and sometimes edema.
Do horses die from it? Sometimes, but rarely.
I asked dozens of veterinarians if they had ever seen a horse die of EIA.
None had. I’ve been a horseowner and trainer for more than 40 years, and I’ve never even seen a horse seriously ill from EIA.
Ask the US Department of Agriculture (USDA) how many horses die from EIA and the answer is "we don’t have any idea." Yet it is the Code of Federal Regulations, Diseases in Horses, which provides individual states the opportunity to adopt a quarantine or euthanize (slaughter) means to eradicate the disease.
And most states are doing just that---quarantining and killing useful, apparently healthy horses which test positive for EIA. Has there been eradication of the disease over the last 30 years? Of course not!
Why?
Money!
