Question: What major city’s drinking water contains tiny crustaceans?
Answer: New York City’s water contains microscopic shellfish called copepods, nearly invisible to the naked eye. If spotted in a freshly poured glass of water, they resemble specks of white dust. None of the cleaning strategies New York uses on its water—ultraviolet light, chlorine and so on—can kill them. On the other hand, the copepods eat mosquito larvae found in the water, making it safer. And the copepods themselves are said to be safe to consume, unless you’re Jewish, in which case you have a thorny theological problem because Jewish law prohibits eating shellfish (or, presumably, drinking them).
