Webinar: Reemergence of New World Screwworm: Implications for Wildlife

By Abbey Canon

The World Organisation for Animal Health (WOAH) regional office for the Americas is hosting a webinar on the potential wildlife impacts associated with the reemergence of new world screwworm on August 19.

The new world screwworm has reappeared in several countries of the region, raising concerns about its impact on human and animal health and biodiversity. While it has historically been addressed from an animal health perspective, its relationship with wildlife poses new challenges. Some species can act as reservoirs or vectors, facilitating their spread. This situation calls for a coordinated response that integrates the animal health, environmental and conservation sectors. A ‘One Health’ approach is key to the prevention, surveillance and control of this disease. 

  • Date: 19 August, 8am CDT
  • Mode: Virtual 
  • Language: English/Spanish 
  • Agenda: Available here (English Spanish)

Why get involved?   

This webinar will bring together the regional wildlife network to address this issue from a ‘One Health’ and biodiversity perspective. It will be a unique opportunity to learn about concrete experiences and lessons presented by specialists from different countries in the region.

At a time when disease pressure continues to challenge pork production systems across the United States, vaccination remains one of the most valuable and heavily debated tools available to veterinarians and producers.

Speaking at the 2025 Four Star Pork Industry Conference in Muncie, Indiana, Dr. Daniel Gascho, veterinarian at Four Star Veterinary Service, encouraged the industry to return to fundamentals in how vaccines are selected, handled and administered across sow farms, gilt development units and grow-finish operations.

Gascho acknowledged at the outset that vaccination can quickly become a technical and sometimes tedious topic. But he said that real-world execution, not complex immunology, is where most vaccine failures occur.
