The New York Times points out that China is only the third most successful producer of dubious food. Federal inspectors refused more shipments from India and Mexico last year:
China has had much-publicized problems with contaminated seafood — including a temporary ban late last month on imports of five species of farm-raised seafood from China — but federal inspectors refused produce from the Dominican Republic and candy from Denmark more often.
For instance, produce from the Dominican Republic was stopped 817 times last year, usually for containing traces of illegal pesticides. Candy from Denmark was impounded 520 times.
The comparison itself is slightly dubious; Denmark's candy was rejected because of improper labeling, whereas Indian shrimp was actually tainted with Salmonella. But I think we'll all feel safer when Denmark executes its food czar.
