Discover the latest on avian flu's impact on the poultry and dairy industries, human health, and the price of eggs.

The bird flu virus is affecting people and dairy cattle in the Valley, but the biggest impact is among poultry flocks – and egg prices – as the avian flu outbreak enters its third year in the U.S.

A famous female falcon that has lived atop UC Berkeley's Campanile bell tower for years has been missing in recent weeks along with her latest mate, and experts who monitor the birds worry that they might have fallen victim to the highly contagious avian flu.

A health alert has been issued for pet owners, as veterinarians are seeing cases of bird flu among cats. Dogs can also contract H5N1, experts said.

Inflation in the costs of feed and fuel and labor have contributed to rising egg prices, and farmers have been investing in biosecurity measures to help keep the virus away. So production costs also appear to be at an all-time high, according to the U.S. Bureau of Labor Statistics' producer price index.
