Avian influenza confirmed in Tamil Nadu’s Cuddalore, over 1,500 chickens culled

On November 5, officials in Cuddalore district collected a dead chicken from a local poultry farm and sent the carcass to the National Institute of High Security Animal Diseases (NIHSAD) in Bhopal for testing. The laboratory examined the sample for viral pathogens and on November 13 reported a positive result for the H5N1 strain of avian influenza. This confirmation marked the first laboratory‑verified case of the highly pathogenic virus in the state of Tamil Nadu. Health authorities immediately notified the state veterinary department and began a coordinated response to contain the outbreak.

In response to the confirmation, the Tamil Nadu Animal Husbandry Department ordered the culling of more than 1,500 chickens from the affected farm and nearby holdings to break the chain of transmission. The birds were humanely disposed of according to standard bio‑security protocols, and the department announced compensation for farmers who lost livestock. Local officials also set up quarantine zones around the farm, restricted movement of poultry and poultry products, and increased surveillance in surrounding villages. These steps aim to prevent the virus from spreading to other farms or to wild birds.

The outbreak matters to readers across India because the poultry sector supplies a large share of the nation’s protein intake and contributes significantly to rural incomes. An H5N1 incursion can lead to trade restrictions, higher egg and meat prices, and heightened public concern about food safety. The government has therefore urged poultry owners to report sick birds promptly, enforce strict hygiene measures, and cooperate with veterinary officials. Ongoing monitoring and rapid response are essential to protect both animal health and consumer confidence.
