The fight against New World Screwworm is getting expensive. NCBA says full eradication is costly, which is why prevention is a top priority.
“The dominoes in Central America fell fast, and we saw it from November of last year up and through the winter into the spring, we saw this disease move quickly through Central America into Mexico, and that is why such an urgent concern for the United States now because it is right at our southern neighbor, and we’ve got to make sure we keep it out of the U.S. cattle herd. It is an extremely expensive disease to eradicate once you have it, so prevention is worth everything here,” said Sigrid Johannes of the National Cattlemen’s Beef Association.
One facility producing sterile flies is up and running in Panama. Mexico is currently working on another, with one planned in Texas later this year.
The Texas Department of Agriculture confirmed a New World Screwworm case about 119 miles from the Texas border, near Zapata, Texas, and north and west of the Rio Grande Valley.
