# Ideal Fly Weather Sparks Sudden Screwworm Resurgence

> The USDA confirmed more than 40 U.S. New World screwworm cases in November, with the article attributing the resurgence to warm, humid weather favorable to the fly. Sterile-fly production remains below the amount the article says is needed, while Texas’s planned facility is not expected to operate until April 2027; cattle imports from Mexico also remain below earlier levels.

## Why it matters

More infestations could cause cattle losses and constrain already-tight U.S. supplies, lending support to cattle prices. Limited sterile-fly capacity and subdued Mexican imports could prolong that supply risk.
