Nagaland has intensified surveillance and containment operations following the outbreak of African Swine Fever (ASF) across several districts, officials said on Saturday, 23 May. The move follows similar emergency measures already in place in neighbouring Mizoram, where the disease has caused cumulative losses of over ₹1,011 crore since 2021, underscoring the scale of the threat facing the Northeast's pork economy.

Restrictions and Containment Measures

A senior official of Nagaland's Animal Husbandry and Veterinary Services (AHVS) Department confirmed that district administrations in affected areas have imposed restrictions on the import, transport, and sale of pigs and pork products to prevent further spread. The AHVS Directorate said it is closely monitoring the outbreak through district veterinary officers and field staff actively engaged in surveillance, containment operations, awareness campaigns, sample collection, and implementation of bio-security measures.

The department issued a five-point advisory urging citizens to immediately report any sudden illness or death of pigs to the nearest veterinary institution, avoid unauthorised movement of pigs and pork products from affected areas, and maintain strict farm hygiene. People were also warned against disposing of dead pigs in rivers, streams, forests, or open public spaces, as improper disposal could aggravate the outbreak.

Why It Matters for Farmers and Markets

ASF is a highly contagious viral disease affecting pigs. Critically, it does not infect humans and is not classified as a public health concern — but its economic toll on pig farmers is severe. Pork is one of the most widely consumed meats in Nagaland, forming an integral part of traditional cuisine and daily meals across communities. Officials warned that the outbreak and resulting restrictions are expected to significantly impact local markets and the livelihoods of thousands of pig farmers and traders dependent on the pork economy.

The AHVS appealed to pig farmers, traders, transporters, village councils, colony authorities, and the general public to cooperate fully with veterinary authorities. It also urged media organisations to disseminate only verified departmental information to prevent misinformation and unnecessary panic.

Mizoram's Losses: A Warning for the Region

The scale of damage in Mizoram illustrates what Nagaland is now racing to prevent. According to officials of Mizoram's Animal Husbandry and Veterinary Department (AHVD), the state incurred losses of around ₹115 crore between March and December 2025 alone, with over 9,710 pigs dying from ASF and more than 3,620 pigs culled during that period.

Since March 2021, more than 72,000 pigs have died in Mizoram due to ASF, affecting over 12,500 pig-rearing families and causing cumulative financial losses of ₹1,011.27 crore over nearly five years. Around 52,980 pigs have been culled since 2021 as part of disease-control measures. The Central government has so far provided ₹14.51 crore as compensation to affected farmers, while the Mizoram government has sought an additional ₹24.94 crore from the Centre.

Cross-Border Movement: A Recurring Risk Factor

Experts believe that the cross-border movement of pigs and pork products is a key driver of recurring ASF outbreaks in the region. Myanmar's Chin State shares an unfenced border with six Mizoram districts — Champhai, Siaha, Lawngtlai, Hnahthial, Saitual, and Serchhip. Mizoram also shares a 510-km unfenced border with Myanmar and a 318-km border with Bangladesh, making disease surveillance along these corridors particularly challenging.

The annual pork trade across the eight Northeastern states is estimated at ₹8,000 crore to ₹10,000 crore, with Assam remaining the largest regional supplier. Any sustained disruption to pig farming in Nagaland and Mizoram threatens to ripple across this entire supply chain. The AHVS said it will continue coordinated scientific and administrative interventions to protect pig farmers and contain the disease's spread across Nagaland.
