An outbreak of highly pathogenic avian flu is ravaging the U.S. food supply, infecting birds in all 50 states and spreading to mammals including humans. Disturbing new reports show that it’s in Americans’ food now, too. Experts say “there is always a chance the virus may evolve to more easily transmit among humans.” Scary stuff.

The bird flu outbreak has cost U.S. taxpayers billions of dollars in rising food costs, new government oversight of the food supply, and industry bailout money, too.
