NCBA’s Woodall says the goal is complete eradication — not just from the U.S., but from Mexico and Central America, ultimately pushing the fly back to its original range in South America.

The tiny, annoying pest can wreak $6 billion in losses annually to U.S. cattle production due to decreased weight gain or milk production, veterinary needs and control measures.

Outgoing USDA Secretary Tom Vilsack sent a letter to Mexico’s Secretary of Agriculture acknowledging the progress made in reopening cattle trade between the two countries following the detection of New World Screwworm, but says more action is needed to resume trade.
