# 2nd New World screwworm case in Cochise County confirmed

> Arizona agriculture officials confirmed a second New World screwworm case in Cochise County, this time in a domestic horse with no known travel history. The case is about 45 miles from the first, a dog infected in late October. A new 20-kilometer Infected Zone is being set up, with animal movement restrictions and suspended self-inspection.

## Why it matters

The spread of screwworm into a new Southwest location tightens livestock movement and raises the risk of further restrictions on cattle shipments from Mexico. That supports US cattle prices by limiting supply and trade flows.
