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 event is slated for July 22-24 in Rochester, N.Y., with an agenda focused on the theme of “Clearing Hurdles to Improve Milk Quality.”
Limiting stress and maintaining a strong relationship with a veterinarian are vital for an Oklahoma rancher’s success in fighting disease issues.
Mexico has committed to eliminate restrictions on USDA aircraft and waive customs duties on eradication equipment aiding in the response to the spread of New World Screwworm (NWS).
Mexico has until April 30 to follow protocol to stop the spread of the pest and eliminate current restrictions slowing eradication.
When a virus moves into a new geographical range or is reintroduced into a country that has maintained a negative status for a long period, SHIC’s Megan Niederwerder says it’s critical to reassess the risk to the U.S.
H5N1 is different than other new swine disease outbreaks because USDA has jurisdiction over H5 in any animal, so they have the regulatory authority, says Scanlon Daniels, DVM.
Soon after the discovery of highly pathogenic avian influenza (HPAI) strain H5N1 in dairy cattle, scientists learned that milk was a primary vector in spreading the disease from cow to cow.
One of the easiest and most effective biosecurity practices to adopt is having separate footwear and clothing for wearing on and off the farm or ranch. Check out the other five ideas our industry experts recommend.
APHIS emphasizes new protocols in place to monitor for the pest before cattle enter the U.S.
Spearheaded by National Economic Council Director Kevin Hassett and USDA Secretary Brooke Rollins, the plan prioritizes enhanced biosecurity measures and medication to control the spread of the virus and moves away from mass culling of infected flocks.
U.S. dairy cattle tested positive for a strain of bird flu that previously had not been seen in cows, the U.S. Department of Agriculture said on Wednesday, ramping up concerns about the persistent spread of the virus.
USDA APHIS announced protocols to ensure safe movement of animals while mitigating the threat of New World Screwworm.
Toothless guidelines, inadequate testing and long delays in releasing data -- echoes of the missteps during the Covid-19 pandemic -- have squandered opportunities for containing the outbreak.
Calving during the winter months can present some unique challenges, so being prepared with supplies and supplemental nutrition will help.
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.
The report echoes calls by other scientists to ramp up the surveillance of felines, which are susceptible to the virus and have a high mortality rate. The AVMA says several cases in cats linked to poultry or wild bird exposure had been reported before the outbreak began in dairy cows last spring.
Any existing herd health problems are amplified by HPAI H5N1, practitioners report. Some are asking regulatory agencies for more consistent testing and reporting protocols. They are also encouraging producers to invest dollars in better nutrition and cow comfort resources.
Scientists are ringing bells of warning about this virus, telling us to take action now. I hope we’re listening.
NCBA Policy director urges cattle producers to be diligent and watch for New World screwworm flies.

The Nov. 22 closing of the southern border to cattle imports from Mexico due to detection of New World Screwworm in a cow brings up questions regarding the history and future of trade with the country.
U.S. and Mexican officials are working together on pre-export inspection protocols before resuming live cattle imports into the U.S. The use of sterile flies is also a priority to help control the spread of NWS in Mexico.
New World Screwworm is a serious veterinary pest that can cause severe damage to livestock and wildlife populations. The detection of New World Screwworm in Mexico and the subsequent USDA actions may have significant implications on trade and travel.
A new study by a broad team of researchers at Iowa State University’s College of Veterinary Medicine helps explain why dairy cows infected by highly pathogenic avian influenza are shedding the virus in their milk. Their findings could help develop biosecurity measures aimed at slowing the spread of the illness.
The project, developed by Cooperative Extension livestock specialists and veterinarians, aims to mitigate profit, production and financial risks to cattle producers.
