Bird flu outbreaks have led to a surge in egg prices in several countries, including the United States and Japan, where the price of eggs has reached a record high. The U.S. has seen over 14 million egg-laying chickens die from the infection, with an additional 8 million infected in the last 30 days, leading to a temporary suspension of production by the largest U.S. egg producer, Cal-Maine Foods. In Japan, bird flu has been found in poultry farms, leading to a 20% increase in egg prices.
