Unintended consequences of bird flu are growing.

FOX News Radio's Kerin McCue reports:

The U.S. hasn't bought eggs from Europe for over a decade. But, with the spread of the H5N2 virus known as bird flu across Midwest farms, that's about to change.

The virus has killed nearly 50 million chickens. More than half that number were egg-laying hens. They provided 80 percent of the eggs used for what's known as the 'breaker market': Those that are used in processed foods like mayonnaise and cake mixes.

But, fewer chickens means fewer eggs. Prices for eggs and egg products have jumped more than 200 percent in the past month alone. Now, eggs purchased from Germany, France and Holland among other nations will soon be used in baked goods from coast to coast.
