A blaze that swept through four large hog barns in east-central Saskatchewan killed all the animals inside, fire officials reported Wednesday.

Dave Elash, deputy fire chief for the town of Ituna, said the fire broke out at a livestock operation near the small community of Jasmin, about 100 kilometres northeast of Regina.

The barns are owned by an Ontario-based company, Hypor. Hypor specializes in producing breeding stock for other barns that raise hogs for meat.

While no number of dead pigs was provided, each barn can house hundreds of animals.

RCMP reported that the fire started some time late on Tuesday night. The Ituna Fire Department, from the town about 15 kilometres away, was dispatched at 11:10 p.m. CT. Additional crews from Kelliher and Melville also worked on controlling the blaze.

Their efforts were successful in saving a number of outbuildings, a residence and feed hoppers.

The operation employed 18 people. When the facility was constructed in 1999, it was valued at $8 million.

The cause of the accident was under investigation by the Saskatchewan Office of the Fire Commissioner and the Melville-Ituna detachment of the RCMP.
