The U.S. government is taking action to stop ‘cow flu.’ Is it too little, too late?

The U.S. government announced new measures yesterday to slow the spread of the H5N1 influenza virus among cattle, following the revelation that milk sold commercially in 10 states contained fragments of the virus. An order issued by the U.S. Department of Agriculture (USDA) restricts the movement of dairy cattle between states and mandates the reporting of infected cows.
