When I was a kid, my grandma (and many other families and hawkers) used painted (yes, painted, not lacquered) chopsticks for the family. I saw paint peeling off especially after a few rounds of dips in hot soup dishes. I stopped using those and starting using western fork, knife and spoon. My mom had a gift set from her ex-employer where she worked as a part-time babysitter when she was a teenager. Incredibly, the set is still here in use today, looking as good as just bought last month.
Not to say I don't like chopsticks, my dad and me were the two most skilfull handlers of chopsticks in the family. But there needs to commonsense. Chopsticks with paint that peels off or plastic that don't remain straight after a few dips into hot soups shouldn't be used for eating unless you don't mind eating paint and plastic.
