The price of a dozen eggs in the US exceeded the cost of a pound of ground beef. A global bird flu that has wiped out about 100 million poultry and high production costs have pushed the price of a carton of twelve eggs to a record $4.82 in January, up from less than $2 a year earlier. Meanwhile the price of a pound of ground chuck has fallen to $4.64 from a 2022 peak of $5.12 last August.
