Learn about NWS impact, detection, and eradication in this informative webinar 

The New World Screwworm (NWS) is a dangerous pest affecting livestock, pets, and sometimes humans. Its larvae cause serious injuries by burrowing into the flesh of living animals, leading to severe health consequences or even death. In the U.S., NWS outbreaks have historically caused millions of dollars in losses. For example, the 1976 outbreak in Texas led to a staggering $132.1 million in response costs, equivalent to $731.8 million today. If NWS were to re-establish in the U.S., the economic damage could reach over $700 million annually in Texas alone, with broader state-wide losses exceeding $1.8 billion. 

This webinar aims to equip participants with essential knowledge on the NWS life cycle, clinical signs, and its economic impact. It will also cover how to detect and report infestations, key interventions for eradication, and available support resources. The target audience includes veterinarians, animal health technicians, and various animal health organizations.
