US Ag Secretary Rollins says agency is preparing to open New Mexico port to livestock imports next week after closure due to new world screwworm

New Mexico ports are a secondary channel relative to the larger Texas crossings, so a single port reopening restores only part of the flow; the precedent in past disease episodes is that full normalization of northbound feeder cattle arrivals lags the first reopening by weeks, keeping imports tight in the interim. The transmission channel runs through feeder and live cattle futures, where constrained Mexican inflows have historically supported prices given the already small US herd. Screwworm eradication is a slow, sterile-fly based process with a long track record, and re-detection risk has on previous occasions triggered renewed closures, which is the tail worth pricing. The follow-ons are whether the Texas crossings follow on similar terms, the inspection conditions attached, and any further detections north of the border.
