Brazil’s Ministry of Agriculture and Livestock (MAPA) has confirmed a second Newcastle disease outbreak in the southern state of Santa Catarina, at a commercial turkey farm in Coronel Freitas. The new outbreak was identified within the restriction zone established following the first case, confirmed on 18 October 2026 at a turkey farm in Nova Itaberaba.
The second outbreak was detected through intensified surveillance in the affected area. Official veterinary services have initiated epidemiological investigations and containment measures, including the sanitary depopulation of the affected flock. According to MAPA, the proximity of the two premises required only a minor adjustment to the existing restriction zone.
A 60-day animal health emergency remains in force across four municipalities: Nova Itaberaba, Águas Frias, Coronel Freitas and Nova Erechim.
The first outbreak had already prompted restrictions on Brazilian poultry exports. According to MAPA’s update of 21 October, Malaysia and Mexico suspended imports of specified poultry products from across Brazil, while China, Saudi Arabia and Chile introduced restrictions on certain products originating from Santa Catarina.
Brazilian authorities continue discussions with importing countries to provide information on disease control measures and facilitate the resumption of trade.
Separately, MAPA reported the detection of pigeon paramyxovirus type 1 (PPMV-1) in pigeons outside the emergency zone, with no epidemiological link to the outbreaks in commercial poultry. The ministry stated that this finding does not constitute a Newcastle disease outbreak under World Organisation for Animal Health (WOAH) definitions.
