Quarter Horse named Thunder (Equine) Signalment 16.0 yr intact female weighing 1200.0 lb. Was in good health previously. Agent Exposure Honcho Herbicide (not specific agent id) Suspected exposure occurred on Dec 12, 2010 at 12:00 PM CST¿1 day (not specific ). Exposure involved 0.0 Not App (not specific) orally. The exposure was accidental, and occurred at field/pasture. [Note : Owner's neighbor's nephew sprayed product on neighbors pasture a few days ago. Owner found evidence that her horses were sticking their head through fence and ingested small area (about 100 feet) of treated pasture. Thunder became acutely ill the afternoon and passed within three hours of becoming ill. This AM both the ponies developed diarrhea. The mare is anorexic and letharic. (by KW on Dec 13, 2010 at 10:22 PM)] Because the amount was somewhat consistent, the patient was considered to be at medium risk of developing clinical signs. If signs develop, there is low risk that those signs will be life-threatening. [Note : If exposed to wet product, that is properly diluted, mild colic may be noted. More significant irritation/colic may be noted if exposed to concentrate. Previously unpalatable plants may be palatable after being treated with product. (by KW on Dec 13, 2010 at 10:22 PM)] Clinical Status Weakness {Musculoskeletal} Begin: Dec 13, 2010 at 02:00 PM CST Status: Severe End: Dec 13, 2010 at 05:00 PM CST Status: Death Diaphoresis {Integumentary} Begin: Dec 13, 2010 at 02:00 PM CST Status: Unknown End: Dec 13, 2010 at 05:00 PM CST Status: Death Trembling {General Disorders} Begin: Dec 13, 2010 at 02:00 PM CST Status: Unknown End: Dec 13, 2010 at 05:00 PM CST Status: Death Death {General Disorders} Permanent: Dec 13, 2010 at 05:00 PM CST Status: Death Potential Cause Honcho Herbicide Because the time course was somewhat consistent, the amount was somewhat consistent, and the findings were poorly consistent, this substance was considered to have doubtful likelihood of causing the clinical situation.
