Confirmed pseudorabies detections in two small U.S. swine herds have prompted precautionary import limits from Mexico, but officials emphasize commercial pork remains safe for consumers. Pork muscle cuts unaffected by Mexico’s current restrictions, the U.S. Meat Export Federation and USDA officials said, while some other product categories face temporary holds.
USMEF reported that since early May exporters have had loads of certain products unable to clear into Mexico due to those precautionary measures. Offal and skins restricted — pork byproducts such as skins and viscera are the items most affected so far, while trade in standard muscle cuts continues under existing protocols. USMEF said it expects further guidance from USDA and urged that Mexico follow World Organization for Animal Health guidelines.
Trade volumes illustrate Mexico’s importance as a buyer: in March 2026 U.S. pork exports to Mexico reached 103,808 metric tons, a year-over-year increase in both volume and value, underscoring why market access for variety meats and bone-in items matters to U.S. producers and exporters. Disruptions to byproduct shipments have the potential to affect specialized processors and established trade flows for those items.
Trade and market impact
USMEF and industry groups say the restrictions are targeted and temporary, with the immediate commercial impact limited to specific product lines. Officials are monitoring shipments and working with Mexican animal health authorities to clarify which product classes are under hold and to restore clearance where appropriate. Exporters with loads in transit have reported delays while paperwork and risk assessments are resolved.
Federal and state animal health authorities are coordinating the response. USDA has said there may be limited, short-term effects on exports of live swine or swine genetics, but maintained that the detection does not pose a risk to consumer health or to the safety of commercially produced pork. Iowa Secretary of Agriculture Mike Naig reiterated that pseudorabies is not a food-safety threat and praised coordinated state, university and USDA response efforts.
NPPC CEO Bryan Humphrey also stressed that biosecurity protocols in place for decades are being used to manage the event and that consumers can continue to enjoy U.S. pork products. Producers seeking more technical guidance have been directed to industry resources, including interviews and briefings with animal health experts such as Dr. Anna Forseth of NPPC.
Disease and response
Pseudorabies is a contagious swine disease spread by direct pig-to-pig contact and contaminated equipment, clothing or breeding animals; it persists in feral swine populations even though commercial U.S. herds have been free of endemic PRV. In the current detections, investigators traced a link between a Texas outdoor herd with potential feral swine contact and a small commercial facility in Iowa that later received animals.
USDA’s Food Safety and Inspection Service has updated its Export Library with advisory language regarding Mexico; USMEF says more specific export guidance is likely to follow as authorities consult on appropriate measures. USDA continues to state the current detection does not pose a risk to consumer health or affect the safety of the commercial pork supply.
