If you thought 2025 couldn't get any weirder, allow the screwworm to hold your beer. Canada has slapped a ban on cattle imports from Texas after the Lone Star State confirmed a second calf infected with the flesh-eating parasite known as the New World screwworm - and then, for good measure, declared an outright state of disaster over the outbreak, according to BBC News.
So what exactly is a screwworm?
Before you scroll away in horror, here's the nightmare fuel you didn't ask for but absolutely need: the New World screwworm (Cochliomyia hominivorax) is a parasitic fly whose larvae literally burrow into the living flesh of warm-blooded animals - and yes, that includes humans. The larvae feed on living tissue, which, if left untreated, can be fatal. The insect was eradicated from the United States decades ago, making its reappearance in Texas about as welcome as a skunk at a garden party.
Texas goes full disaster mode
Texas officials didn't mess around once the second case was confirmed. The state moved quickly to declare a state of disaster, signaling that authorities are taking the outbreak seriously and mobilizing resources to contain what could become a very expensive, very disgusting agricultural crisis. The screwworm's last major U.S. presence cost the livestock industry enormous sums before eradication efforts finally worked in the 1960s - nobody wants a repeat performance.
Canada says "thanks, but no thanks"
Canada's response was swift and blunt: Texas cattle are not crossing the border until this situation is under control. The import ban reflects just how seriously livestock disease officials treat screwworm outbreaks - once established, these parasites can spread rapidly through herds and wildlife populations alike, making containment an urgent priority rather than a polite suggestion.
How did it get here?
The exact origin of this current outbreak has not been fully confirmed in available reporting, but screwworm cases have been detected in recent years moving northward through Central America and Mexico, raising alarm bells for U.S. agricultural authorities. The fear has long been that it was only a matter of time before cases appeared on American soil again.
For now, Texas ranchers are on high alert, Canadian border agents are waving off Texas beef shipments, and the rest of us are googling "screwworm" and immediately regretting it. Stay tuned - this one is far from over.
