Flesh-eating parasite found in Texas leads to Canadian restrictions
Animal diseases can spread quickly and have serious consequences for farmers and entire industries. That is why countries often act fast when new threats appear. Even temporary restrictions can have a major impact on trade and livestock movements.
Protecting animal health
Canada has introduced temporary limits on livestock imports from Texas after the discovery of New World screwworm in the state, reports DallasExpress. The move is meant to stop the dangerous parasite from entering Canada.
The Canadian Food Inspection Agency said livestock, including horses, cannot enter Canada if they came from Texas or had been in the state during the previous 21 days. The restrictions were put in place after the parasite was found in a calf in Texas.
Canadian officials said the country does not have New World screwworm and wants to keep it that way. They said the measures are necessary to protect animal health.
The parasite comes from a fly whose larvae feed on living tissue. The larvae can cause severe wounds in livestock, wildlife, pets, and in rare cases humans. Untreated infestations can lead to infections and even death.
Officials noted that Canada’s colder climate makes it difficult for the fly to survive over long periods. Still, they warned that the parasite could live temporarily during the warmer summer months.
Cases reported in Mexico
New World screwworm is already found in parts of South America and the Caribbean. Cases have also been reported in Mexico. Canada already bans several livestock imports from Mexico and has strict rules for horses entering from the country.
The U.S. Department of Agriculture recently confirmed additional cases in Texas. The total number of detections in the state has now reached four since the first case was identified on June 3.
The restrictions could affect rodeo events and livestock transportation. Texas is an important center for professional rodeo competitions. The new 21-day rule could complicate participation in events such as the Calgary Stampede in July.
Texas officials criticized Canada’s decision. A spokesperson for Governor Greg Abbott said authorities are working quickly to contain the outbreak. He argued that the restrictions are too broad and not supported by science.
Canadian authorities are asking veterinarians and animal owners to watch for symptoms and report suspected cases immediately.
