I have one Chinese friend who married a Chinese American and had a child with her. He then got a job opportunity in Shanghai and took it, leaving her in the US with the child because the food safety is so bad in China. Knowing nothing about the particulars of food safety in China, I thought this was insane. I brought it up to two other Chinese born coworkers, and they thought it was reasonable to raise the child in the US because of food safety concerns.

Briefly searching around the net, the food safety in China does seem very scary.
