USDA bungles mad cow case
US - If you've seen grim videos from the British countryside showing a cow in the final stages of bovine spongiform encephalopathy, it's a safe bet you want nothing to do with mad cow disease. The animals can't stay upright, but they continue to try. They stumble and fall, their eyes unfocused and foam bubbling from their mouths. Their bodies shake uncontrollably. It's an ugly way to die.Source: SantaMariaTimes.com
