Chinese authorities have implemented enhanced border security measures and begun destroying infected livestock following the emergence of an uncommon foot-and-mouth disease strain in the country’s northwestern regions, according to government officials who believe the outbreak originated from neighboring countries.
Agricultural ministry officials announced over the weekend that they initiated the destruction of infected animals and sanitization procedures in affected zones after the disease impacted herds containing 6,229 cattle across Gansu province and the Xinjiang Uyghur Autonomous Region.
Agricultural experts noted this marks the first detection of the SAT-1 variant—a disease form commonly found in Africa—within Chinese borders, emphasizing that current domestic immunizations designed for the more prevalent O and A variants offer no defense against this strain.
The SAT-1 variant has expanded from African territories to regions throughout the Middle East, West Asia and South Asia since 2025.
Government officials stated Monday that the disease entered Chinese territory through northwestern border areas, which share boundaries with Kazakhstan, Mongolia, Russia and additional nations.
Border regions including Xinjiang and Gansu received directives to increase surveillance activities and block disease transmission through contraband activities or unauthorized animal movement, based on government announcements.
“The current outbreak threatens a large region and prevention and control are under severe pressure,” said Rosa Wang, analyst from Shanghai JC Intelligence Co.
The situation develops while Russia confronts a serious livestock disease emergency in the Siberian Novosibirsk area, which neighbors Kazakhstan and sits approximately 1,200 kilometers (750 miles) and 2,500 kilometers from the affected locations in Xinjiang and Gansu respectively.
A March 20 analysis from the U.S. Department of Agriculture suggested that China’s response magnitude might signal an unverified foot-and-mouth disease outbreak. Russian officials have rejected claims of any such outbreak.
Animal diseases have previously entered China from Russian territory, including African swine fever in 2018 and foot-and-mouth serotype O during 2000 and 2014.
“It is not out of the question that China could adopt restrictions on Russian livestock products if it has reason to believe the transmission originated there,” said Even Pay, director at Trivium China. “But it’s more challenging if such outbreaks aren’t reported.”
Chinese officials announced this week that the strain transmits rapidly, may result in significant production damages and causes death rates above 50% among young livestock.
The SAT-1 variant primarily transmits through direct animal contact but can also spread through airborne particles, with aerial transmission being more potent than the common A and O variants, according to industry specialists.
Emergency veterinary medicine approvals were granted Wednesday for two SAT-1-targeted vaccines manufactured by Zhongnong Weite Biotechnology Co., Ltd, based on China’s National Veterinary Drug database records. Industry watchers believe the immunizations could become available within one month.
China’s livestock industry has been struggling with declining meat costs, excess production capacity and reduced consumer purchasing.
“If it is not controlled well, cattle prices could drop first and then rise again later as herd numbers fall,” said Xu HongZhi, analyst at Beijing Orient Agribusiness Consultants.
