An official with the Marathon County Sheriff’s Department reported 75 to 80 cattle died in the fire.

According to WOAW News 9, up to 25 more cows were able to escape the blaze. However, authorities note that an unknown number of these surviving cows may be euthanized due to injuries related to smoke inhalation.
