I'm surprised they didn't mandate culling the whole farm like they do poultry.From MSU.
"What happens in a dairy herd with HPAI? What should I expect if my herd became infected? This case report describes what one farmer has faced since herd infection began."

Not that I'm advocating Mass culling. Never will develop resistance if the strong are culled.
