What happened

Canada bans Texas cattle over flesh-eating screwworm outbreak in US Canada's food inspection agency has announced a temporary ban on livestock from the US state of Texas after flesh-eating screwworms were discovered in calves this week.

Why it matters

Cows and horses that were in Texas anytime within 21 days before crossing the border into Canada would not be accepted into the country, an agency news release said.

Common ground

The announcement comes after the US Department of Agriculture (USDA) said the parasite had been found in a second calf in Texas - the leading US beef and cattle producer.
