For the last few weeks I've seen people searching for "toxic chopsticks" on Nuketown, which I assumed was in regards to some sort of hoax, but since no one ever sent me the text, I couldn't debunk it.
This morning I tried searching Snopes.com and came up with the story "Chopsticks". According to Snopes, the original e-mail claims that disposable chopsticks can cause cancer via bleach left over from their creation. It's based on a post made to Chinese-language message boards, and it's definitely bogus. The problem folks in the United States are most likely to encounter with disposable chopsticks is an excess of sulfides, which can cause asthma attacks, skin rashes and other side effects in those who are allergic to them.
