# US eases screwworm ban on Mexican cattle, but beef prices unlikely to budge | Reuters

> USDA will reopen the Santa Teresa, New Mexico port to Mexican cattle after blocking imports for over a year over New World screwworm. The pest was found in a Texas calf in June, and US case counts have stayed relatively contained while Mexican cases keep rising.

## Why it matters

Reopening adds feeder cattle supply, but analysts expect limited relief for record retail beef prices, so the feeder and live cattle complex may see modest bearish pressure.
