The world is getting smaller, yes, but also more ridiculous in some ways. Why would you take a chicken grown here and send it to China for processing. Just the length of time itself is going to make the chicken more vulnerable to disease and such. And this is a foreign nation whose hygeniec processes we can not control.
The USDA only has jurisdiction over the United States and has no power to regulate what goes on in China. That said, it can forbid the importation of Chicken from China. It should be looked into. It is a long way to transport food stuffs, and the long shipping time is frought with complications that could easily spoil or taint meat.
