What is Newcastle disease?; characteristics, impact and the outbreak that triggered alerts in Brazil
The disease of Newcastle is a highly contagious and severe viral illness affecting both domestic poultry and wild birds, caused by a type 1 paramyxovirus (APMV-1). It leads to serious respiratory, digestive, and neurological disorders that can cause mass deaths among infected birds within days. Following the detection of a virus outbreak at a commercial poultry facility in Brazil’s municipality of Nova Itaberaba, Mexico’s National Service for Agrifood Safety and Quality (Senasica) suspended imports of chicken meat and related products from Brazil to protect national poultry and livestock production. Symptoms vary depending on the virus strain’s virulence and include respiratory distress, neurological issues like paralysis and twisted necks, and digestive problems such as green diarrhea. Transmission occurs through contact with bodily secretions, contaminated food or water, and improperly disinfected equipment. While the disease does not pose a risk to human health if meat and eggs are properly cooked, it has significant socioeconomic impacts on the industry due to the need for mass culling of flocks and temporary trade restrictions.
Mexico suspended chicken imports from Brazil on Monday due to an outbreak of Newcastle disease detected in a commercial turkey farm in southern Brazil, according to the Ministry of Agriculture and Livestock (MAPA). The move was announced by Mexico’s Secretariat of Agriculture and Rural Development (Sader) through the National Service for Agrifood Health, Safety and Quality (Senasica), aimed at protecting national poultry production and preventing the entry of the disease into Mexican territory. Newcastle disease is a highly contagious viral infection affecting both domestic and wild birds. It causes severe respiratory, digestive, and neurological disorders that can lead to mass deaths among infected birds within days. According to the World Organisation for Animal Health (WOAH) and Senasica, symptoms vary depending on the virus strain's virulence, classified as lentogenic, mesogenic, or velogenic. In its more aggressive forms, clinical signs include respiratory distress, neurological paralysis, digestive issues, and a sharp drop in egg production. The outbreak was confirmed in a commercial poultry farm in the municipality of Nova Itaberaba, located in the state of Santa Catarina. Brazilian authorities have closed the facility and implemented measures to contain and eradicate the outbreak. The suspension applies to all poultry-related products, including live birds, fertile eggs, and meat. The restriction will remain in place until information on the outbreak's management and sanitary conditions is received and evaluated under international protocols. This is the second time in 18 months that Mexico has suspended chicken imports from Brazil. In May and June 2025, Mexico, China, the European Union, and other Latin American countries halted chicken imports from Brazil due to an avian flu outbreak. Brazil exports 30 percent of its chicken production, with Mexico being one of its main destinations. According to Sader, the measure aims to protect national poultry production since Mexico is considered free of Newcastle disease. The disease does not pose a risk to humans or food safety through properly cooked chicken or eggs, but it has significant socioeconomic impacts on the industry, requiring the preventive slaughter of entire flocks and temporarily closing trade borders. The restrictions apply to both commercial imports and items travelers attempt to bring into Mexico from Brazil. Products affected include poultry meat, offal, fertile eggs for breeding, chicks up to three days old, singing birds, ornamental birds, birds of prey for sale, and pets from Brazil included in the restriction. As part of preventive actions, the General Directorate of Animal Health, attached to Senasica, deactivated the corresponding Zoosanitary Requirements Sheets on its platform, which prevents the entry of goods covered by the suspension. The decision follows confirmation from Brazil's MAPA that the virus was present in a commercial broiler chicken production unit in Nova Itaberaba, Santa Catarina.

Mexico has suspended the importation of chicken products from Brazil due to an outbreak of the Newcastle disease detected in a commercial turkey farm in southern Brazil. The Mexican Ministry of Agriculture and Rural Development stated that this measure aims to protect Mexico's poultry industry, as the country is considered free of the disease. The suspension applies to live birds, fertile eggs, and other avian products, not just meat. The disease affects poultry but does not pose a risk to humans. This is the second time in 18 months that Mexico has halted imports from Brazil over similar health concerns, following a previous suspension linked to avian flu in 2025. Brazilian authorities have closed the affected farm and are implementing control measures.
