Clearly you misunderstood GP. Bird flu in a farm mean at worst 5% death rate for them, so clearly death isn't why GP talked about the danger for big ag.

In my country, if any factory farm is hit by any virus, the meat is considered tainted and cannot be sold (wouldn't be bought by big retailers anyway) until the virus is cleared.

For poultry it can means 3 months of throwing eggs away. It's more economical to kill all the chickens and start from scratch. If the contamination reach your neighbours, they will do the same thing (so you want to do it early, and radically).
