Brazil, the world’s largest chicken exporter, confirmed a second case of
Newcastle disease — a highly contagious avian virus — on Sunday night at a
commercial turkey farm in Santa Catarina, close to last week’s reported positive
site. Santa Catarina, Brazil’s second-largest poultry-producing state, accounted
for about 23% of the country’s chicken exports through end‑September. Several
buyers have imposed partial restrictions on poultry products from the entire
state, though processors can reroute shipments via plants in other states, which
may constrain the broader impact on Brazilian exports.
