Bird Flu outbreak affects farms in Yorkshire

A bird flu outbreak in Britain, the first in six years, has led to government intervention. Farm workers noticed a decline in egg production and duck deaths, prompting tests that confirmed the H5 strain. While not harmful to humans, it poses a threat to farmers. Control measures include culling and movement restrictions. The outbreak's spread to other European countries raises concerns, with efforts to identify the source and prevent further outbreaks.
