Overview
- SENASA reported a positive H5 highly pathogenic avian influenza result at a commercial breeder farm in Ranchos, triggering immediate interdiction of the site and activation of its contingency plan.
- Control measures include a 3 km perifocal zone with movement restrictions and a 7 km surveillance area, supervised culling, and subsequent cleaning and disinfection of facilities.
- The agency said it will notify the World Organisation for Animal Health, with temporary export pauses to partners that require country‑free status, while trade can continue with those recognizing zoning and compartmentalization.
- Earlier in the weekend, the official Martínez laboratory confirmed H5 in wild birds at the La Salada Grande reserve in General Madariaga, affecting brown-hooded gulls, coscoroba swans and black-necked swans.
- SENASA urged strict biosecurity under Resolution 1699/2019 for commercial farms and protective housing and hygiene for backyard flocks, reiterated rapid reporting channels, and noted poultry meat and eggs do not transmit the virus to consumers.
