Made in China?

With all the conflab recently about tainted pet food and
toothpaste imported from China, I started to wonder how toxic the
frozen brine shrimp, bloodworms, etc also manufactured and packaged
there might be to our fish.
I asked at my LFS, and they said that, although made in China,
the brand they carried was "sterilized" (Hmmm.). I note that the
"Frostbites" brand carried by Walmart also originates in China.

Just wondering...
