America's public concern over bird flu appears to have risen following the spread of the H5N1 strain of the virus from Asia into Europe, according to The Brock Report. Some 57% of Americans are concerned that bird flu may spread to the U.S., but only 24% think it will show up this year, based on a survey of 1,043 adults done in late January by the Harvard School of Public Health.

About 46% of respondents who eat chicken say they would stop if bird flu hits the U.S. poultry industry.
