FoodPolitics.com too political for China? Really?

My not quite son-in-law is stage managing a play in China, and writes:

I looked at the pictures of Mayor Koch and you in your kitchen last week and it worked fine.  Now I’m here in Shenzhen & Internet Explorer isn’t able to open your Blog.   See!  That’s what you get for all those nasty things you said about the Chinese baby formulas and pet foods!

I guess he’s referring to my posts on the deliberate adulteration of pet food and infant formula with melamine.  Is this site really blocked?  If so, is it really a threat to the Chinese state?

Seems far-fetched, no?  Anyone know anything about this?
