> The number of confirmed New World screwworm cases in US domestic animals has risen to 128, with half detected in the last two and a half weeks.

## Why it matters

Rapid spread among US livestock constrains cattle supply and supports live cattle prices. The planned Nogales reopening would add Mexican feeder cattle imports, which could weigh on feeder cattle prices if the border reopens as planned.
