Screwworm Outbreak: What's Really at Stake

The USDA has confirmed a screwworm case in South Texas, marking the first detected breach of the US-Mexico border by the parasite.
The screwworm is especially dangerous to livestock, causing deep, festering, life-threatening wounds, with estimated annual losses of $900 million.
The USDA is setting up a unified Incident Command Team and sending response personnel to the area, with a 20 km zone around the detected infection for quarantine and surveillance.
The Sterile Insect Technique, which involves aerial bombings of sterile male flies, is the most effective method for controlling the parasite.
The US has expanded surveillance and trapping efforts in Texas, with a $750 million sterile fly production facility under construction in South Texas.

The Full Story / Background & Context

The screwworm, also known as Cochliomyia hominivorax, is a parasitic fly that lays its eggs in the wounds and openings of warm-blooded creatures, allowing its larvae to feast on the living animals, causing deep, festering, life-threatening wounds. The parasite was once endemic to the US, but was eradicated in the 1960s amid a concerted effort to annihilate its population.

The USDA estimates that keeping screwworms out of the US has saved the livestock industry $900 million each year. - USDA Report
