NCBA Responds to USDA Announcement Again Closing Southern Ports to Livestock Shipments

The National Cattlemen’s Beef Association (NCBA) responded to the latest announcement that the U.S. Department of Agriculture (USDA) is again closing southern ports of entry to shipments of cattle due to the detection of New World screwworm in Veracruz, Mexico. USDA discovered this new case in northern Veracruz, indicating that screwworm has traveled 160 miles northward of the location where sterile flies are currently being dropped.

“A key part of USDA’s strategy for protecting American agriculture is continuously monitoring conditions on the ground,” said NCBA CEO Colin Woodall. “Secretary Rollins has been working to balance the economic needs of U.S. cattle producers who rely on imports while at the same time protecting the overall U.S. cattle herd. The New World screwworm’s northward movement jeopardizes the safety of American agriculture, which is why Secretary Rollins paused cattle movement again until we can push the screwworm further from our border.”

Video: Leman Swine Conference: Vaccination strategies to reduce PRRS virus recombination

Dr. Jay Calvert, Research Director with Zoetis, recently spoke to The Pig Site’s Sarah Mikesell at the 2023 Leman Swine Conference in St. Paul, Minnesota, USA, about his conference presentation on porcine reproductive and respiratory syndrome (PRRS) virus recombination.

“The number one problem in PRRS these days from a vaccine point of view is the emergence of new strains of PRRS. Since the beginning, we have had new strains and a lot of diversity,” said Dr. Jay Calvert. “We thought we knew it was all about mutation changes in amino acids and the individual strains over time, but they take on new characteristics.”

With the onset of more common whole genome sequencing and recombination analysis, Dr. Calvert says there is another mechanism, and recombination seems to be a key factor.
