The United States' outbreak of highly pathogenic avian influenza is causing significant disruption to Korea's domestic parent stock market. The majority of parent stocks in Korea are imported from the US, but import bans in several US states have led to delays and uncertainties in these imports. This is particularly concerning for four Korean companies that rely heavily on US imports. The poultry industry is worried about the potential collapse of the market and is considering the possibility of importing poultry from other countries, such as the UK. Some have proposed easing regionalization standards to stabilize domestic chicken prices.
