2 Bar C Ranch managers, herdsmen, and staff are proactively taking extra measures to protect our herds from the New World Screwworm (NWS) parasite by increasing the frequency of daily rotational checks to ensure early detection and prevent infestation. In addition, we have implemented a rotational fly spray regiment.
• The NWS is a pest that affects all hosts equally. The screwworm fly lays its eggs in open wounds of humans, livestock, and wildlife.
• Screwworms do not infest other food sources like meat, fruits, or vegetables; they require a live host.
• Infestation, infection, and death among livestock emphasizes the need for timely detection and intervention.
The cattle herd in the US is currently at its smallest national inventory in 75 years. The 2 Bar C team is ready and has implemented early detection protocols for the pest. We haven’t found the pest in our herd yet, but we know it’s on its way.
