The Agricultural Defense Agency of Pará, Brazil, is implementing an Epidemiological Surveillance Plan to monitor Avian Influenza and Newcastle Disease in poultry, in response to the world's largest epidemic of the highly pathogenic H5N1 virus. This outbreak, affecting countries like Colombia, Ecuador, and Chile, poses a risk to Brazil, the world's third-largest poultry farmer and largest chicken meat exporter. The plan involves collecting samples from 1,122 birds and 16,930 biological samples from 98 farms across 21 municipalities, using a team of 22 professionals. The goal is to demonstrate the absence of these diseases in industrial poultry, supporting Brazil's status as a country free from Highly Pathogenic Avian Influenza. This preventive measure is crucial for avoiding commercial restrictions that could negatively impact the production chain.
