RE: Never Knew NY had Moose
There was one killed and left (except for its head) late last year in Putnam county, NY. There was another one in Putnam county last year that had to be put down because of brain worm Phil mentioned
'About the moose's brain worm
Deer carry the worm, a.k.a. meningeal worm, but aren't usually affected by the parasite. When it's ingested by a different animal - moose, elk, goats, sheep, llamas and alpacas - the parasite moves into the brain or spinal cord, causing neurological problems, and can be fatal.
Symptoms depend on the number of worm larvae present in the nervous system and the location, but can include weakness, paralysis, a head tilt, circling or inability to eat. The only way to confirm infection is to find the parasite in the nervous system, which requires a necropsy examination.
Livestock can be treated with drugs when an infection is suspected based on symptoms.
