Screwworm in Texas: What to Know

Screwworm searches rose after New World screwworm was confirmed in a Texas calf, raising livestock and animal-health concerns.

By Emily Foster/Family Planner

Why people are searching

Health searches often reflect personal concern, news, screening questions, or public-safety updates, so precision matters more than speed. New World screwworm is a parasitic fly whose larvae can infest wounds in warm-blooded animals. A confirmed Texas case drew attention because the pest had been largely eradicated from the U.S. decades ago.

What to verify

Animal owners should follow USDA, Texas Animal Health Commission, and veterinarian guidance. Suspected cases in animals should be reported through official channels. Use qualified medical sources and talk with a clinician for personal symptoms, screening decisions, or treatment questions.

Health note

Search results are not a diagnosis. Use reputable medical sources, check dates, and get professional care for urgent or personal concerns.
