This article is misleading because it does not mention Trump or Musk or Doge, and they were mostly responsible for the new outbreak in the US. Mexican cattle imports were banned in the US in 2024 because of the screw worm. Then trump allowed mexican cattle imports in February 2025 even though the screw worm situation was not resolved. Then, in March 2025, Musk's DOGE cut funding for COPEG, the organization that suppresses the screw worm in Panama.

Then the screw worm really spread over Mexico and the United states. The administration then stopped mexican cattle imports in the summer of 2025 again, panicked because of the spread of the screw worm, then started them again in the fall of 2025, panicked because of high beef prices.

Panama was the ideal place to control the screw worm because it was a small chokepoint. The flies that birth the screw worm cannot fly far by themselves, the screw worm moves with cattle, and cattle almost always moves by land. So COPEG acting at the chokepoint was a cheap and effective way to keep the screw worm from entering north america. The article talks about how great COPEG is, it does not mention that Musk's DOGE cut their funding.

But now the screw worm is all over Mexico and the US, the choke point is lost. Now they are spending much more money all over Latin America and the US with much smaller effect.
