Well then you aren't paying attention. They killed 166 Million chickens over three years & didn't stop the spread of the bird flu. They would have a farm of 1,000 chickens where 1 bird had a positive test for bird flu... They would kill the entire flock of chickens, all 1,000 of them. Then, on top of that - they would compensate (at a much lower than market rate) farmers for the chickens they killed. The results was astronomical egg prices that kept some consumers unable to get eggs.
So Bird Flu impacts chickens & chickens have to have the entire flock culled when 1 chicken gets sick... Why didn't Chicken Meat products fall to the same scrutiny of supply and demand? Tyson Chicken products were still packed in every freezer - raw Chicken products still packed the Fresh Meat sections - the price of Chicken products didn't go sky high... Only the eggs. If only the eggs went crazy in price and not the price of Chicken Meat products as well -- then something doesn't add up.
Bird Flu literally cooks out and dies so long as you actually cook the eggs & poultry at a proper temperature. 166 million chickens killed - over something that got 200 people sick - where only 6 people died from co-morbidity of Bird Flu and other factors. Only 1 out of every 1,750,000 citizens got sick with bird flu. Then factor in how Chicken Meat based products didn't go scarce nor rise in price.
The only way that works is if the Meat Chicken Farms somehow magically managed to dodge the Bird Flu while the Egg Chicken Farm managed to magically exclusively catch the bird flu.
