Officials have confirmed the first case of highly pathogenic avian flu in a Wisconsin dairy herd.
Prevention, detection and long-term control of these diseases are key to avoiding a $300-billion impact.
Southern rust has now been confirmed in at least 15 states, and with high heat and humidity this week, along with strong winds, agronomists are encouraging farmers to scout their corn fields, as conditions are ripe for the disease to spread.
The image, the smell, the emotions: five cattle producers and veterinarians from around the world share their first-hand experience with New World screwworm.
Identifying the flesh-eating parasite, which actually isn’t a worm, is key to keeping it out of the U.S. Recognizing a problem in an animal might come down to seeing a larval infestation in unusual circumstances.
As the fight to keep the flesh-eating parasite out of the U.S. intensifies, the economic impact on ranchers and the industry is top of mind. “This pest will be one that leaves quite a mark on our economy,” says one veterinarian.
Native to east Asia, the ALHT was first detected in New Jersey in 2017. Since then, it has spread to more than 20 states with recent confirmations in Illinois, Michigan and Iowa.
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.

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.
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.
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.
USDA announced on Oct. 30 the first reported case of H5N1 in a pig in an Oregon backyard farm.
Now that the mystery illness impacting some dairy herds has been revealed as the same strain of Highly Pathogenic Avian Influenza that has been impacting the U.S. poultry flock, pork producers are asking questions.
Ohio has become the sixth state where dairy cattle have tested positive for highly pathogenic avian influenza (HPAI), also known as bird flu.
The Idaho State Department of Agriculture announced that HPAI, known as highly pathogenic avian influenza, or bird flu, has been found in dairy cattle in Idaho.
The Texas Department of State Health Services reports that a human case of bird flu has been confirmed in Texas and identified in a person who had direct exposure to dairy cattle presumed to be infected with the disease.
In an effort to increase its biosecurity measures against HPAI, also known as bird flu, the Nebraska Department of Agriculture has issued a 30 day restriction on the importation of dairy cattle.
While HPAI has been detected in predatory mammals that prey on infected birds, this is the first identified case of HPAI in domestic livestock in the U.S.
The study of animal disease emerged as a systematic science in the 18th century, and USDA first engaged in such work in 1883. USDA’s new National Bio- and AgroDefense Facility is on the verge of opening in Kansas.
The case occurred in a person who had direct exposure to poultry and was involved in the culling process of poultry with presumptive H5N1 bird flu, reports the Centers for Disease Control and Prevention.
