      Still-edible?

      What's your definition of edible? Palatable, or non poisonous? haha. Does it have to be considered food to be edible?
    • bostjan64
      If you are starving, can you eat it and survive?

      They eat dirt cookies in the Sudan. Roses are also edible. And kids usually try eating crayons. They won't kill you. I've eaten mold before. But I wonder if any molds are poisonous...

      Penicillin can be derived from moldy bread. However, poisonous mycotoxins grow on grains, peanuts and hard cheese, so if it looks moldy, it's much safer to toss it.

      I think I'd rather eat dirt than mould, if those were the only two choices. I've eaten mouldy bread before and it didn't kill me, but it certainly was not an experience I'd wish to relive, and not simply because of the poor taste.

      Bostjan, Did you look at the link? That fish is not purple!
    • bostjan64
      Yeah. I'm not sure how to take the fish one, though. It's definitely blue or bluish-green, but it sounds like the colouration is from a maybe-toxic liver metabolite that has to be (most likely) cooked out of the meat before it can be safely consumed. I don't want to discount it on a technicality, since it's not really certain that it can't be eaten in its raw, blue state.

      Is it really that difficult for you to accept? You said foods that are naturally blue. This is a food that is naturally blue. " Lingcod a member of the greenling family isn't the only West Coast species to turn up with blue-green meat. Its cousins, the rock greenling and the kelp greenling, are sometimes tinted turquoise. " https://www.outdoorhub.com/news/2016/08/02/extremely-rare-blue-lingcod-caught-alaska/
    • Linda Joy
      " The cause of this rare turquoise color is due to a bile pigment called biliverdin, which is responsible for turning the blood serum of these fish that freakishly odd color, but how this pigment gets into the tissues and flesh of the fish, or why only some lingcod turn this striking shade, still leaves biologists puzzled. Biliverdin is also the pigment that is responsible for that greenish color sometimes seen in bruises." And they mentioned blue sushi, and nowhere did it say anything about it being toxic.
  • Blue cheese
