Avian influenza has led to a significant increase in egg and chicken meat prices in various countries, including historic highs for eggs in 2023. The price increase was initially due to a rise in feed prices in 2021, followed by bird flu outbreaks. The situation is particularly severe in Latin America, with the United States, Japan, and Europe experiencing significant losses in laying hen populations. The European Union has seen egg prices rise by an average of 31.1% in February 2023, with notable differences between countries. The disease is also impacting poultry trade, with Argentina and Chile temporarily losing their global market status. The situation could potentially affect global poultry trade and exports to Europe, especially if Brazil is affected. Legislation such as New Zealand's ban on caged poultry is also contributing to the reduction in the number of laying hens.
