The New World screwworm fly, a flesh-eating parasite, has reappeared in Texas for the first time since 1966, threatening the $113 billion U.S. cattle industry. Two new cases were found in a calf and a dog, bringing the state's total to four. The flies were eradicated in the 1960s using sterile male flies. The recent detection in Mexico in 2024 raised concerns. The flies are unusual as their larvae feed on living tissue.

Southern US states are implementing new rules to combat the spread of the New World Screwworm, a flesh-eating parasite. Florida Agriculture Commissioner Wilton Simpson issued an emergency rule restricting the movement of warm-blooded animals, the parasite’s preferred breeding ground, into high-risk areas.
The New World screwworm parasite has expanded beyond Texas with new cases confirmed in multiple locations, marking the most significant outbreak since the pest was eradicated in the 1960s. Federal and state agencies are implementing emergency measures as the flesh-eating larvae threaten the $113 billion cattle industry, with Florida now joining containment efforts through animal movement restrictions. The USDA confirmed four total cases as of June 8, 2026, including infections in both livestock and pets.Toronto Star+4
🐄 Expanding Infection Zones
Two additional screwworm cases were confirmed in Texas on June 8, bringing the state's total to four infections. The parasite has been detected in:
- Cattle herds
- Domestic dogs
- Previously eradicated areas
Officials warn the outbreak could spread further without enhanced containment, as the larvae feed on living tissue of warm-blooded animals.The Independent+2
🌎 Cross-Border Containment
Emergency protocols now span multiple states:
- Florida's animal movement restrictions
- Texas quarantine zones
- USDA surveillance programs
Canada's livestock import ban remains in effect, while Mexico's 2024 outbreak continues to fuel concerns about northward migration.The Korea Times+2
💰 Economic Fallout
The crisis threatens to:
- Disrupt beef supply chains
- Increase production costs by 20%
- Trigger additional trade restrictions
Ranchers face compounded challenges from early herd liquidations and feed shortages.The Korea Times+2
🚨 Response Measures
Current containment strategies include:
- Accelerated sterile fly production
- Detection dog deployments
- Public education campaigns
Officials emphasize these may prove insufficient if the parasite establishes permanent footholds.National Post+2
