The Brazilian government has detected the first case of highly pathogenic avian influenza (H5) in backyard birds in the municipality of Maracajá, causing alarm in the poultry industry. While the occurrence does not compromise Brazil's status as a country free of influenza, the government has decided to suspend the sale of live birds and poultry meat outside the state of Santa Catarina as a preventive measure. The potential interruption of Brazilian poultry meat exports could have significant consequences for both the meat protein and grain markets, as the poultry sector is a large consumer of corn and soybean meal.
