Agriculture Secretary Brooke Rollins discussed the recent outbreak of screwworm, a flesh-eating parasite affecting cattle in Texas, during an interview on CNBC’s Squawk Box. Rollins stated that the outbreak is a consequence of the Biden administration's policies, specifically citing 'open borders policy' and issues related to border security. She noted that the infestation began to spread from Mexico in 2023, suggesting a connection to immigration policies.
Screwworm, which was eradicated in the U.S. in the 1960s through the release of sterile male flies, has raised concerns among farmers regarding its potential impact on the food supply and beef prices. Rollins mentioned that upon taking office, she inquired about the measures in place to combat the outbreak, indicating that not enough had been done.
While Rollins attributed the outbreak to federal policies, budget cuts made in March 2025, which affected programs aimed at controlling animal diseases, may have contributed to the situation. These cuts included reductions to the U.S. Agency for International Development and other agricultural programs that previously supported outbreak investigations and responses.
Texas Governor Greg Abbott has issued a disaster declaration for Zavala and Uvalde counties in response to the outbreak. The USDA has not yet commented on the situation.
