As bird flu spreads in the United States, are there are any risks of the virus from drinking milk or eating eggs? Here's what you need to know, according to experts.

Over the past 60 years, the influenza virus has continued to drift and shift. In 1968, a shift once again caused a pandemic. In 1976 and 2009, concerns that the virus had shifted led to [fears that a new pandemic loomed]. But Americans were lucky once again.

Researchers have stressed that bird flu still poses a minimal risk to the general public, though that may change as the virus continues to circulate and potentially mutate. But the many empty shelves in stores and higher prices on the eggs that people can find have raised concerns among consumers about the safety of the egg supply.
