Immortality has never really been addressed in the series, unless you count Brook's Yomi Yomi no mi, which isn't really immortality. Anyway, I don't think that anyone will eat a mermaid. Immortality takes away from a big theme in the series of grabbing life by the horns and enjoy it, you only live once. Immortality doesn't fit in with that.
