On Wednesday, June 20, 2018, an attending veterinarian confirmed an outbreak of botulism in Chester Basin, Nova Scotia, Canada. A 12-year-old Arabian/Quarter Horse cross gelding and a 26-year-old Arabian gelding were euthanized. An 8-year-old Standardbred mare and a 7-year-old and 10-year-old Zonkey jack and jenny are showing clinical signs, including inability to swallow, muscle fasciculations/tremors, and increased recumbency. One horse also presented with a stiff-strided gait and another with colic. 

From eight to 20 horses were exposed, but no quarantine is in place as botulism cannot be spread from horse to horse.
