Canada has announced temporary restrictions on livestock imports from Texas following the detection of flesh-eating screwworm larvae in a calf at a ranch in La Pryor, Texas. This is the first confirmed case of the parasite in the state since the 1960s, prompting the Canadian Food Inspection Agency (CFIA) to prohibit the entry of animals from Texas that were present there within 21 days before arriving at the Canada-U.S. border. The CFIA emphasized that while Canada’s colder climate is generally inhospitable to the screwworm, the larvae can survive short periods during warmer months. The agency has urged vigilance among animal owners and travelers to Texas, advising them to inspect their pets for signs of infestation. In response to the threat, Texas Governor Greg Abbott has declared a state of disaster and committed state funds to accelerate the construction of a $750 million sterile fly breeding facility aimed at controlling the screwworm population. A second facility in Mexico is also set to begin operations soon. Both facilities will produce sterile male flies to mate with wild females, preventing further reproduction of the larvae.
