How many of the recalls due to salmonella or E. Coli contamination were due to foods made in the US though?
All we have to worry about from China is the use of toxic chemicals, not bioagents. Yum, melamine.
Stuff from China can be just as good as stuff made elsewhere. The problem is a universal one - you get what you pay for. You can get lousy junk made in the good old US of A. You can get cheap crap from Japan. And you can get top-quality merchandise from China. But if you offer 50% of the going rate to get a product manufactured, there's going to be more than a few corners cut. Tolerances will be slackened, so the acceptable failure rates will be increased, and materials will be lower-grade. This will happen in any country.
China just has looser regulations, so they have less problem making cheap junk, as opposed to countries whose governments have imposed at least some guidelines which hold industry to certain standards of responsibility and quality. That is where the problem lies.
