They’re back… and they are eating livestock from the inside out.

Fox News Radio's Jeff Monosso Joins The Ray Stevens Show to talk about a gruesome biosecurity threat that hasn't been seen in the U.S. for decades: the New World screw worm. From the nightmare-inducing science of how these parasites feed on living flesh, to the government's wild plan to drop millions of sterile flies from airplanes, we break down exactly what is happening in Texas and New Mexico.

But is this just a freak nature outbreak, or is it a direct symptom of a broken border? We look at how international cartels, black-market beef, and current immigration policies through the notorious Darién Gap might have just opened the floodgates for a multi-million dollar agricultural disaster.
