Mexico Cattle Import Reopening Expands October 26
Mexico Cattle Imports Resume at More Border Crossings as USDA Announces New Dates for Livestock Trade
Oklahoma cattle producers and Southern Plains feedlots could see additional livestock entering the United States as federal officials move forward with reopening more border crossings to Mexican cattle imports. The U.S. Department of Agriculture (USDA) announced October 20 that cattle imports will resume through Columbus, New Mexico, on October 26, with another crossing in Nogales, Arizona, scheduled to reopen November 30, provided animal health and operational requirements are satisfied. The announcement marks another step toward restoring livestock trade that has been disrupted by concerns over the dangerous New World screwworm parasite.
The Mexico cattle import reopening comes at a critical time for the American cattle industry, particularly in Oklahoma and neighboring Texas, where tight livestock supplies, high cattle prices and challenges rebuilding domestic herds continue to influence the market. Mexican feeder cattle have historically played an important role in supplying Southern Plains feedlots, and restrictions on those imports have complicated purchasing decisions for cattle feeders. While additional border crossings could gradually improve livestock availability, USDA officials emphasize that protecting American herds from New World screwworm remains the priority, and future reopening decisions will depend on disease surveillance and inspection safeguards.
Mexico Cattle Import Reopening Adds New Mexico and Arizona Border Crossings
According to the USDA Animal and Plant Health Inspection Service's October 20 announcement, cattle imports are scheduled to resume through the Columbus, New Mexico, port of entry on October 26. The reopening is part of a phased approach intended to restore livestock movement between the United States and Mexico while maintaining measures designed to prevent the introduction of New World screwworm.
The latest announcement follows earlier reopenings at Douglas, Arizona, in August and Santa Teresa, New Mexico, in September. By adding crossings gradually, federal officials can evaluate inspection procedures, animal health conditions and the operational capacity of each location before allowing additional livestock shipments. The approach is intended to balance the economic importance of cross-border cattle trade with the potential consequences of introducing a destructive livestock parasite into the United States.
USDA has also identified November 30 as the next scheduled reopening date for cattle imports through Nogales, Arizona. However, that reopening remains conditional on the availability of appropriate inspection facilities, operational readiness and continued animal health assessments. The date should therefore be viewed as a planned milestone rather than an unconditional guarantee that cattle shipments will begin.
The agency also announced that horses and other equines will be permitted to enter through Santa Teresa beginning October 26, subject to additional quarantine requirements. Those safeguards reflect the fact that New World screwworm can affect multiple species of warm-blooded animals, making border surveillance important beyond the cattle industry alone.
For livestock businesses that depend on cross-border trade, the reopening of additional ports could provide more flexibility in scheduling shipments and moving animals to American feeding operations. However, the pace of recovery will depend on inspection capacity, transportation arrangements and the number of cattle that meet import requirements.
New World Screwworm Threat Continues to Shape USDA Livestock Restrictions
The phased reopening follows months of concern about New World screwworm, a parasitic fly whose larvae infest wounds and feed on the living tissue of warm-blooded animals. The parasite can cause severe injuries, secondary infections and potentially fatal complications when infestations are not detected and treated promptly. Cattle are particularly vulnerable, although other livestock, wildlife, pets and humans can also be affected.
According to USDA APHIS information on the current New World screwworm situation, federal animal health officials continue monitoring the parasite and coordinating prevention efforts intended to protect livestock in the United States. The agency's response includes surveillance, animal inspections and measures designed to reduce the risk of infested animals crossing the border.
New World screwworm differs from many other flies because its larvae feed on living tissue rather than dead or decaying material. Infestations can begin when adult flies lay eggs near wounds or other vulnerable areas of an animal's body. Once the eggs hatch, the larvae can cause extensive tissue damage, making early detection and treatment essential.
The threat is especially concerning for cattle-producing states such as Oklahoma, where an outbreak could create substantial animal health challenges and economic losses. Ranchers could face additional veterinary expenses, increased livestock monitoring requirements and disruptions to normal cattle movement if the parasite were introduced and became established.
Federal officials are therefore proceeding cautiously as they restore livestock imports. Inspection requirements and other safeguards are intended to identify potentially affected animals before they enter the domestic cattle population. The reopening of a border crossing does not mean the screwworm threat has disappeared, nor does it eliminate the possibility that restrictions could change if animal health conditions deteriorate.
USDA has indicated that additional ports will be evaluated as circumstances permit. The agency's decisions will continue to reflect both the need to support legitimate livestock trade and the responsibility to protect American agriculture from a parasite capable of causing widespread damage.
Oklahoma Cattle Producers Watch Border Reopening as Herd Supplies Remain Tight
For Oklahoma ranchers and cattle feeders, the return of Mexican cattle imports could eventually influence livestock availability across the Southern Plains. Mexican feeder cattle have traditionally been purchased by American feeding operations, particularly in Texas and surrounding states, where they enter feedlots before being marketed for beef production. Restrictions on those shipments have added another complication to an industry already dealing with limited domestic cattle inventories.
In an October 20 interview with Oklahoma Farm Report, outgoing Texas Cattle Feeders Association Chairman Laphe LaRoe discussed the effects of restricted Mexican cattle imports and the challenges facing producers as the industry considers rebuilding the American cattle herd. LaRoe noted that some Texas feedyards previously relied on Mexican cattle for a substantial portion of their inventory, making disruptions to that supply particularly important for regional feeding operations.
The economic effects extend beyond individual feedlots. When cattle supplies are limited, feeding operations may face greater competition for available animals, while ranchers must evaluate whether current market conditions justify retaining additional breeding females or expanding their herds. Those decisions are influenced by cattle prices, feed expenses, pasture availability and expectations about future market conditions.
LaRoe also pointed to the complications created by favorable cattle prices and uncertain weather conditions. Although high prices can provide strong returns for producers selling cattle, they can also make herd expansion more expensive because retaining or purchasing breeding animals requires substantial investment. Weather uncertainty adds another layer of risk, particularly in regions where drought can limit forage production and increase feed costs.
For Oklahoma cattle producers, the reopening of additional Mexican border crossings may gradually affect the supply of feeder cattle available to regional markets. However, the immediate impact on prices remains uncertain. Import volumes, domestic herd conditions, feedlot demand and broader beef market trends will all influence whether increased livestock movement produces noticeable changes.
The reopening also does not mean trade will immediately return to previous levels. Federal inspection requirements, the availability of eligible cattle and the continued threat of New World screwworm could all affect how quickly shipments increase.
For now, the October 26 reopening at Columbus and the planned November 30 reopening at Nogales represent additional steps toward restoring a trade relationship that remains important to cattle producers on both sides of the border.
For Oklahoma's cattle industry, reopening the border is about more than moving livestock. It is about rebuilding dependable supply channels while protecting the health of the American herd.
As USDA continues evaluating border crossings, the challenge will be maintaining that balance: allowing cattle trade to recover without exposing producers to an animal health threat that could carry consequences far greater than the current market disruptions.
