Things in China that are probably tainted...

1. toothpaste (DEG)
   
2. dog and cat food (melamine)
3. juice (dye)
4. pigs (wastewater)
5. convenience store prepared foods (fake expiration dates)
   
6. milk powder (flour, sucrose)
7. toys (lead paint)
8. McDonald's drinks (Taihu water)
9. fish (heavy metals, hepatotoxins)
10. watermelon (tapwater)
11. cold medicine (DEG)
12. candy, pickles, crackers (formaldehyde, dyes, industrial wax)
13. Budweiser beer (counterfeit)
14. bottled water (bacteria)
    

This list started out as a joke.... but I lost my sense of humour at 14 when I had to start actually thinking of more internationally documented cases in the recent past. Feel free to add a comment if you think of any more.
