OTTAWA — Canada is temporarily restricting the import of livestock from Texas over concerns about a parasitic fly with flesh-eating larvae.
The Canadian Food Inspection Agency says 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.
It comes after an infestation of New World screwworm fly larvae was confirmed this week in a calf in Texas.
The agency says several U.S. states have also taken precautionary measures to mitigate the risk of spread.
