There is a very interesting item on CBC news this morning, which I post in the hopes that all food manufacturers are reading this forum. Much of the industrial pollution in China is carried onto agricultural land in China. There are illnesses in livestock which have not been sorted out. & dead pigs have been dumped in Chinese rivers.* The report was done by Anthony Germain, who is stationed in China.
Now, that kind of information is really going to be hard for that country to correct.
:C
On edit, I heard these reports 4 times. The dead livestock story is separate from the report of Anthony Germain.
