NM Faces Second Screwworm Case as Authorities Expand Surveillance Near Grant County

New Mexico has confirmed a second case of New World screwworm in a horse in Grant County, prompting expanded surveillance, a 12.4-mile infested zone, and broader monitoring with increased fly-trapping and animal inspections to detect and contain any spread, while keeping most animal movements allowed unless risk is identified. Wildlife monitoring and veterinary guidance are part of the response, with updates at ScrewwormNM.org.

Tiny on the scales: all wild land mammals weigh about 20 million tonnes, far less than humans and livestock

Tiny on the scales: all wild land mammals weigh about 20 million tonnes, far less than humans and livestock

A 2023 study estimates the total wet biomass of all wild land mammals at about 20 million tonnes (roughly 3 kg per person), which is far smaller than humanity’s ~390 million tonnes and well below the combined weight of livestock (~630 million tonnes). The weight is concentrated in a few species—white-tailed deer, wild boar, and African elephants—with bats representing the majority of individuals but only a small fraction of total weight. The figure is uncertain and should be read as a ratio illustrating humans’ dominance and livestock impact, not a full biodiversity assessment.

Scotland records two more bluetongue cases as vaccination drive intensifies

Two more bluetongue virus cases confirmed on neighboring farms in Dumfries and Galloway, Scotland, after the first case; all affected animals euthanised and farms under restrictions. Officials say infected midges likely blew in from outbreaks in Ireland and northern England, and vaccination is urged to prevent further spread. The UK has reported hundreds of BTV3 cases this season, though the disease does not affect humans.

Africa's camels tested by record heat and drought

Extreme heat—often above 50C—and prolonged drought across the Horn of Africa and North Africa are driving camel stress, disease, and rising deaths, while reducing milk yields and pushing herders to move their herds in search of water and shade; scientists warn climate change is intensifying heat stress and underscore the need for better veterinary care, water provisioning, and shade to protect these desert-adapted animals.

Screwworm comeback: a dinner-safe scare, but beef prices could rise

Screwworm comeback: a dinner-safe scare, but beef prices could rise

The New World screwworm has reappeared in the United States and targets living tissue in livestock, but public health officials say it does not threaten food safety—meat is still considered safe thanks to veterinary care and strict inspection; the bigger impact is economic, with potential billions in damage to the southwestern US and potential higher beef prices, since infestations affect livestock health and supply rather than the safety or quality of meat already in the food chain.

Screwworm comeback tests U.S. livestock defenses

An outbreak of New World screwworm, a flesh-eating parasite that infests warm-blooded animals, has returned to the United States with 15 confirmed cases in Texas and New Mexico, mainly affecting cattle. Officials are deploying sterile flies, expanding surveillance, and tightening border and movement controls to contain it, warning the outbreak could cost billions if it spreads, even as human risk remains low. The situation echoes the historic success of the sterile-insect technique used to eradicate the pest decades ago.

Screwworm Outbreak Expands Across Texas and New Mexico, Raising Biosecurity Alarm

US screwworm cases rise to 12 across Texas and New Mexico as the parasite spreads beyond initial zones, affecting cattle, goats, sheep and a dog; USDA is releasing millions of sterile flies and deploying the Screwworm Adult Suppression System (Swass) to curb spread, while Pennsylvania imposes import quarantines; officials say the food supply remains safe but the beef industry could be impacted if containment fails.

Texas Expands Screwworm Outbreak as Federal War on Screwworm Goes 24/7

Texas Expands Screwworm Outbreak as Federal War on Screwworm Goes 24/7

Three more New World screwworm cases were confirmed in Texas (a calf in La Salle County, a dog from a New Mexico household, and a goat in Gillespie County), bringing the total to five. Federal and state officials, led by the USDA and Gov. Abbott, launched a wide‑scale response called the “War on Screwworm,” opened a 24/7 emergency command center, and are weighing options including ivermectin in animal feed as they warn the outbreak could threaten the cattle industry with as much as $1.8 billion in potential losses. The administration also announced a new federal adviser, John Bellinger, to help coordinate preparedness and response.

Screwworm resurges in the U.S., forcing a restart of the sterile-fly program

Screwworm resurges in the U.S., forcing a restart of the sterile-fly program

The United States confirmed a natural incursion of the New World screwworm in Texas cattle—the first since 1982—after decades of eradicating the pest with mass releases of sterile male flies. Facing potential billions in economic impact from livestock losses, the USDA is funding a $750 million facility in Texas to produce about 300 million sterile screwworms per week by 2027. While the comeback mirrors the historic campaign, experts note aging facilities elsewhere and a growing debate among bioethicists about using genetic modification to wipe out the species, a method not yet ready for deployment.

Second Texas Case of New World Screwworm Triggers Border Measures

Second Texas Case of New World Screwworm Triggers Border Measures

The USDA confirmed a second case of New World screwworm in a one‑month‑old calf in Zavala County, Texas, near the first case, within a movement‑control zone where sterile insects are released. Canada will temporarily restrict imports of U.S. livestock from affected areas. The USDA says the U.S. food supply remains safe and no meat is at risk, with eradication efforts continuing and heightened vigilance urged for livestock owners.
