Texas Faces New Threat from Resurging New World Screwworm Parasite

Texas is grappling with a resurgence of the New World screwworm, a parasitic fly that poses a significant risk to livestock, wildlife, and pets. The first case in the current outbreak was confirmed on June 3 in a calf in South Texas, with 15 cases reported in the U.S. as of mid-June. If left unchecked, experts warn the outbreak could lead to billions in economic losses, particularly affecting the beef industry. While the risk to humans remains low, the infestation could further drive up beef prices, already at record highs. The CDC has classified the outbreak as a Level 3 public health emergency, emphasizing the need for vigilant monitoring and reporting by healthcare providers.
