The Brazilian Ministry of Agriculture and Livestock (Mapa) has reviewed the certification for poultry and their product exports to 44 countries following an outbreak of Newcastle disease in a commercial poultry production establishment in Anta Gorda, Rio Grande do Sul. The review is part of a bilateral agreement to meet international health requirements and guarantees. The suspension of certification affects poultry meat, eggs, and other poultry products, with the suspension period ranging from 21 days to a 50km radius around the outbreak. This suspension affects countries such as China, Argentina, Peru, and Mexico, and products like poultry meat cannot be exported from areas within a 50km radius of the outbreak. Despite the suspension, products subjected to heat treatment can still be certified for export to certain countries. Rio Grande do Sul, the third-largest chicken meat exporter in Brazil, exported 354 thousand tons in the first half of the year, generating revenue of US$630 million.
