The Winnipeg Humane Society has paid for eight billboard ads critical of the way farmers treat hogs.
They are positioned around Winnipeg and come in the midst of a provincial election campaign.
“Our goal is to educate consumers on the various animal welfare red flags that are associated with industrialized pork production,” said Brittany Semeniuk, animal welfare specialist for the Winnipeg Humane Society.
In February it had a similar campaign directed against dairy farmers and in May against egg producers.
