Key Discussion Points & Insights

1. Breaking: New World Screwworm Facility Announced

[00:55-03:00]

Announcement:
U.S. Agriculture Secretary Brooke Rawlins announced that a new Sterile Fly Dispersal facility will be constructed at Moore Airfield Base, South Texas.
Purpose:
The $8.5 million facility is designed to shore up USDA capability to "detect, control, and eliminate" the New World Screwworm pest, a longstanding threat.
Background on the Threat:
- New World Screwworm is a parasitic fly (Cochliomyia hominivorax) whose larvae infest wounds in warm-blooded animals, often leading to severe harm or death.
- The pest was eradicated in the US by 1982, but recent cases near the southern border have sparked renewed concern.
- Recent Incidents:
  - May 11: Imports of live cattle, bison, and horses from Mexico halted after the pest was found within 700 miles of the U.S. border.
  - November 2024: First case found in southern Mexico, triggering border closure; the border later re-opened in February 2025.
Current & Future Biosecurity Strategy:
- The U.S. relies on a Panama-based facility (with the Panamanian government) to produce ~100 million sterile flies weekly.
- USDA projects eradication efforts may soon require "400 to 500 million flies weekly" (highlighting domestic capacity needs).
Host Insight:

“We’ve talked about it a lot on these shows. It lays eggs in wounds of warm-blooded animals and larvae feed on live tissue, causing severe harm or even death.”

2. Emergence of Asian Longhorned Tick in Iowa

[03:00-04:30]

Urgent Update:
The Asian Longhorned Tick has now been identified for the first time in Van Buren County, southeastern Iowa.
Risks:
- This tick species transmits a protozoan parasite affecting red and white blood cells, leading to bovine infectious anemia.
Management and Biosecurity Recommendations:
- There are currently "no approved treatments" in the U.S. for the disease.
- Prevention measures focus on effective tick control and "proper biosecurity to prevent bloodborne spread between livestock."
Further Resources:

Host Takeaway:

“The best way to protect livestock is through tick control methods and proper biosecurity to prevent bloodborne spread between livestock.”
— Rebecca “BEC” Wanner [04:12]

The Superior way US Agriculture Secretary Brooke Rawlins announced based Sterile Fly Dispersal facility will be built at the Moore Airfield Base in South Texas to help combat the spread of New world screwworm. The $8.5 million facility is part of a plan to enhance USDA's ability to detect, control and eliminate the pest. Now, New World Screwworm is a parasitic fly. We've talked about it a lot on these shows. It lays eggs and wounds of warm blooded animals and and larvae feed on live tissue, causing severe harm or even death. Now the pest was eradicated in the US by 1982, but recent cases near the border have raised alarm. On May 11, imports of live cattle, bison and horses from Mexico were halted when the pest was found within 700 miles of the US border. Previously, in November of last year, 2024, the border was closed when the first case of New World screwworm was found in southern Mexico and then reopened again on February 1st of this year. Now currently the US relies on a facility in Panama operated jointly with the Panamanian government to produce about 100 million sterile flies each week. USDA estimates future eradication efforts may require 400 to 500 million flies weekly. Underscoring the need for for increased domestic capacity, the Asian Longhorn tick has been confirmed for the first time in Van Buren County. Located in southeast Iowa, the Asian longhorn tick carries a protozone parasite that infects red and white blood cells and causes bovine infectious anemia. There are no approved treatments in the United States and the best way to protect livestock is through tick control methods and proper biosecurity to prevent bloodborne spread between livestock.
