Notes: The New York State Department of Agriculture and Markets, Division of Animal Industry, is confirming 2 EHM and 2 EHV-1 cases that are currently quarantined and isolated at a stable in Brewster, NY. The stable has already implemented strict biosecurity measures, temperature monitoring and has been very cooperative during this investigation and situation. The origin of the disease is unknown and still under investigation. Only 1 of the 4 positive horses (an EHM case) competed at Old Salem Farm in North Salem, NY. This horse arrived on the evening of Thursday, March 4th, competed in equitation on March 5th and returned home on March 5th. This horse started to exhibit symptoms on Sunday, March 7th. The other EHM case exhibited symptoms on Monday, March 8th. The 2 EHV-1 cases were sampled due to close proximity to the index case. Old Salem Farm has no known cases of EHV-1 or EHM at this time. Show management is cleaning and disinfecting the facility and following appropriate EHV-1 biosecurity protocols. If you visited or competed at Old Salem Farm during that time, please refer to the AAEP's FAQ for instructions on monitoring your horse. https://aaep.org/sites/default/files/2021-02/EHM_EHV_FAQ_Final.pdf For updated competition information, please visit www.oldsalemfarm.net ;
