A horse was euthanized at the Minnesota State 4-H Show on Friday, Sept. 18, after exhibiting symptoms similar to EHV-1, a highly contagious virus. There were 640 horses entered in different events at the show, reported Bring Me The News.
The University of Minnesota is urging anyone who participated in the event to keep a close eye on their horses for signs of the virus. EHV-1 can cause fever, respiratory issues and neurologic symptoms in affected horses and is spread when horses are commingled at events such as shows, trail rides and races.
The University recommended that exhibitors at the show put in place biosecurity measures such as isolating horses returning home for 21 days and keeping a sharp eye out for fever, nasal discharge and diarrhea in horses who have left the property. University staff also recommend taking a horse's temperature daily; if it's higher than 102 F, a veterinarian should be contacted.
Update: Tests on the euthanized horse later came back negative for EHV-1. A 4-H official clarified that the horse's owners made the decision to euthanize the animal because it was suffering from neurologic symptoms and could no longer stand and did not seem to be improving. The quarantine at the show area has been lifted, according to HorseNation.
