## Transcript

- **Screwworm: second Arizona case confirmed** Officials confirmed a second New World screwworm case in Cochise County, Arizona. This one is in a domestic horse.
- **No known travel history** The horse had no known travel history. The case is about 45 miles from the first, a dog infected in late October.
- **A new Infected Zone** A 20-kilometer Infected Zone is being set up, with animal movement restrictions and suspended self-inspection.
- **Why cattle buyers should watch** Spread into a new Southwest location tightens livestock movement and raises the risk of further limits on Mexican cattle shipments. That supports US cattle prices by limiting supply and trade flows.
- **Screwworm is now in Arizona twice** A second New World screwworm case is confirmed in Cochise County. This time it's a domestic horse with no known travel history.
- **About 45 miles from the first case** The first case was a dog infected in late October. The new case sits roughly 45 miles away, so this is a new location, not the same spot.
- **A new 20 km Infected Zone** Officials are setting up a 20-kilometer Infected Zone around the new case, with animal movement restrictions and suspended self-inspection.
- **Livestock movement gets tighter** Spread into a new Southwest location raises the risk of further restrictions on cattle shipments from Mexico.
- **Takeaway: supply and trade flows** Limited supply and trade flows support US cattle prices. Watch for more movement rules if cases keep appearing.
