Canada temporarily banned Texas livestock due to the ongoing spread of New World screwworm, officials announced June 5. American officials recently identified the flesh-eating parasite in the United States, decades after it was eradicated from the country. The parasitic infection, spread via screwworm flies, poses serious risks to Texas' $15.5 billion cattle industry. The Canadian Food Inspection Agency said it would temporarily halt imports of livestock, including horses, from Texas.
