Arizona agricultural officials say they now have the first detection of H5N1 avian influenza in milk produced by a dairy herd within the state.

H5N1 bird flu is branching out. New data from the Centers for Disease Control and Prevention indicates that a second type of H5N1 has likely spread from dairy cows to humans.

Before future studies would uncover a link between Nipah outbreaks and the felling of native forests for the purposes of fruit plantations, more than 1 million pigs are culled to quell an outbreak that leads to the deaths of 105 people.
