Screwworm ban could see some Stampede competitors making changes
CALGARY — A temporary Canadian ban on Texas livestock, including horses, may force some competitors at the Calgary Stampede to make some unexpected changes on the fly.
The “Greatest Outdoor Show on Earth” kicks off on July 3. The Stampede rodeo is world-famous and one of the most lucrative in North America, with a total prize purse of $2.17 million.
The Canadian Food Inspection Agency implemented the ban this week after an infestation of New World screwworm fly larvae was confirmed in a calf in Texas. It’s the first case confirmed in the state since 1966.
The agency said animals that are from Texas or were present in the state within 21 days of a border crossing will not be allowed into the country.
