Learn which products are conditionally approved and why a strong veterinarian-client-patient relationship is the only way to manage this devastating pest.
New global report warns shrinking investment in animal health is colliding with expanding disease threats, workforce strain and rising biosecurity demands
Surveillance, reporting and veterinary partnerships are framed as critical ways to prevent a single case from becoming a national crisis.
Agriculture Secretary Brooke Rollins broke ground on a $750 million sterile fly facility in Texas and confirmed the border will remain closed until the New World screwworm threat is pushed back from the U.S. border.
New reports highlight the concerning transboundary spread of a new serotype that evades current vaccines and increases the risk of introduction to the U.S.
A new genetic innovation from the Agricultural Research Service aims to produce 100% sterile male flies, maximizing facility efficiency and safeguarding the U.S. livestock industry from NWS.

Megin Nichols, the CDC’s director in the division of foodborne, waterborne and environmental diseases, explains the ties between human, animal and environmental health.
“Most screwworm migration does not come from adult flies making heroic flights northward. Instead, it comes from the movement of infested animals — cattle, deer, wildlife — and yes, even in rare cases, people. Wherever the animal goes, the parasite goes with them,” says Dr. Christopher Lee.
