Texas rolls out free online training to spot livestock pests faster

Texas just launched a free online course to help more people recognize the New World screwworm, a dangerous parasite that burrows into animal wounds. The state needs faster inspections because cattle and goats can’t move freely if there’s a risk of infestation. So far this summer, Texas has found ten cases across five counties—Edwards, Tom Green, Zavala, Gillespie, and La Salle. Most cases involve cattle and goats, but one early report of a dog infestation turned out to be in New Mexico instead. Even though the dog case moved states, officials say it shows how easily this pest can travel with animals that cross borders. The training isn’t only for experts. Veterinarians, animal control officers, and even everyday Texans can now take the course to learn how to spot and report screwworm. The course explains the insect’s life cycle, what wounds look like when infected, and when to call authorities. It also covers the rules for moving livestock safely. More certified eyes on the lookout could help stop the spread before it causes bigger problems for farms and ranches.

Screwworm maggots don’t just hurt animals—they can ruin economies too. Unlike ordinary fly larvae, these maggots eat living flesh, causing severe injury or even death in untreated cases. They’ve been spotted moving north from Panama and are now within about 300 miles of Texas. The last big outbreak in the US happened in the 60s, but now the pest is back, and officials are worried. They’re releasing billions of sterile flies weekly to mix with wild ones, hoping unproductive matings will wipe out the population. Not everyone is convinced the response is fast enough. Some wonder why the first New Mexico case wasn’t caught sooner, or if local vets have enough training to tell the difference between a screwworm wound and a regular infection. Others ask if Texas needs more ground teams besides air drops of sterile flies. Still, state agencies promise daily updates and a public information page so ranchers and pet owners know what signs to watch for. One big question remains: Could humans get infected? Officials say it’s rare but possible. They’ve set up two reporting paths—one for animals, one for people. While the risk seems low, the fact that screwworm was mostly gone for decades shows how quickly pests can return and how much damage they can do. Texas is treating this seriously, but the outbreak also reminds everyone how connected animal health is to food safety, trade, and public well-being.
