The Canadian Food Inspection Agency says it will place temporary import restrictions on livestock entering Canada from affected areas in the U.S. after a case of screwworm was confirmed.
The agency announced Friday that the restriction will include imports of horses, after the infestation was found in a calf in Texas.
“Animals that originate from or were present in the State of Texas within 21 days prior to border crossing will not be accepted into Canada,” the statement said.
The agency says taking the action now is “an appropriate risk mitigation measure” to prevent the spread of screwworm and protect animal health.
The New World screwworm is a parasitic fly with larvae that can eat the living tissue of warm-blooded animals, causing them serious and often deadly damage.
The agency is urging animal owners and veterinarians to be on the look out for signs of screwworm infestations in livestock, which can often appear as a wound that worsens over time and is “accompanied by discharge or foul odour.”
They are also warning Canadians travelling to Texas with companion pets to remain vigilant and inspect their animal regularly for signs.
Presently, there are no confirmed cases of the New World screwworm in Canada. However, the CFIA says it will continue to work closely with U.S. counterparts to assess developments and adjust measures as needed.
