Thanks to Johann the Dog, I found a great blog on the subject of Dog Toys From China, and another about how dog toy imports are an uregulated market. Both are from an awesome dog blog called dog topics.  

I am defintely worried about my Stella's chew toys. I make a lot of plush toys for her but all of her hard chew toys are purchased. She is such a huge chewer, she would not be at all excited if I took her toys away...I am going to have to go home and take a thorough look through her her toybox, I think.
