New World screwworm alert

A parasite the US eliminated decades ago is back on the radar, and the clock starts the moment someone notices a “not quite right” wound. We sit down with Dr. Patrick Webb, Assistant Chief Veterinarian with the National Pork Board, to unpack what a confirmed New World screwworm case in southern Texas signals for pork producers and the wider livestock industry, and why early reporting beats waiting for certainty every time.We walk through how a suspected case typically moves from farm observation to state notification, investigation, and lab confirmation, and what that process tells us about readiness right now. From there, we get practical about containment: unified command, the 20-km infested zone concept, and how disease control measures can affect movement, and day-to-day business continuity. Dr. Webb also points to proven tools, including the sterile fly approach, as part of a multi-layer response that can push the threat back again.The biggest takeaway is simple and actionable: monitor your animals closely, tighten biosecurity, and keep communication open with your herd veterinarian and state animal health officials no matter what state you operate in. Summer conditions raise risk, and movement of infested animals is a key pathway, so fast action protects your herd and your neighbors. For clear guidance on what to look for and how to report, we share the best place to start: screwworm.gov.If this conversation helps you think differently about surveillance, traceability, and outbreak preparedness, subscribe, share it with another producer, and leave us a review so more people find it when it matters.
