Callisse Loos, a deputy fire chief with Mapleton, Minto and Wellington North, said in an email 1,599 pigs died in a barn fire on Sideroad 5 East near Derrynane, east of Kenilworth.
She said firefighters responded around 4:37 p.m. and were on the scene for six hours. No injuries were reported to civilians and firefighters.
The building ended up being a total loss with the deputy chief giving a damage estimate of $1.5 million.
The fire is not considered suspicious but a cause was not able to be determined due to the extent of the damage.
Firefighters from Harriston on route to the fire were also rerouted to a single vehicle rollover on Highway 89 and O'Dwyer's road. Two patients were taken to Louise Marshall Hospital with unknown injuries.
