Farmers fear Johne's disease may threaten milk cows
Washington scientists debate a cattle illness called Johne's disease that may link to Crohn's in humans. The National Milk Producers Federation seeks 1.3 billion dollars from Congress to identify and cull infected cattle, with estimated industry losses at 200 million annually. Officials warn of public health risks from transmission through milk, meat, or water, while dairy producers push for testing and compensation.
