Two people are now facing more than 20 charges under the province's Animal Care Act after nearly 500 hogs were found dead in a barn in Notre Dame de Lourdes in June.

"This is an extremely unusual case and they're very rare. In my 35 years as a veterinarian and five years as chief veterinarian officer I've not seen a case like this," said Dr. Wayne Lees, the provincial chief veterinarian.

Provincial veterinary officials and RCMP officers began investigating the case in Notre Dame de Lourdes in June. The town is located about 70 km southwest of Portage la Prairie.

Along with nearly 500 hogs that were found dead at the site, another 160 had to be put down by officials. About 2,000 animals were rescued. Many of the animals were found living without proper food, water or ventilation.

A week after the animals were discovered, a fire destroyed the barn.

The Manitoba Pork Council said it supports the investigation and said the case is not the norm in the industry.

RCMP continue to investigate and said criminal charges are also pending against the two suspects, in addition to the Animal Care Act charges.
