ASF is wreaking havoc on the swine population in China. Some estimates are that it could kill nearly 50% of the entire Chinese herd of 440 million hogs. Additonally, the virus is pernicious and will last in the environment, for decades. If China does indeed end up losing 200 million pigs, then they will face a shortage of protein of 10 million metric tons. They simply is not enough surplus available for purchase in the rest of the world to make up the shortage. As an example, the entire USA swine output is 76 million hogs, and we are number two in world production behind China.

This is going to affect beef, egg and chicken prices worldwide as well.
The Chinese have, or rather had, massive frozen reserves. However, those are expected to run out in the next few months. Question is, will the Chinese people be patient for a decade or even decades?
