And no, this is not about a reality cook-off show where the cravated judge eats a bone marrow risotto and then dies of a heart attack*
This is the story of a plant in Western Australia that contains a poisonous compound - well there are many - but a plant in the gastrolobium family is especially famous for creating havoc with the colonisers. The names Poison Point, Poison Hill and Poison Swamp are mapped by cattlemen when driving their stock out to the coast to feed in the summertime. They mapped the areas where the gastrolobiums grew and they deliberately kept sheep, cattle and goats away from the beautiful egg and bacon plants.
This plant was later developed by the government and made into a synthetic version of its essence: sodium fluoroacetate or 1080: a biochemical weapon now used to get rid of feral animals such as cats, dogs, pigs and foxes.These animals were driving native fauna into extinction So this pretty little heart-shaped plant became weaponised against the ferals. Most native animals who fed on this plant over millennia were totally immune to its killer effects. This is why it is such a perfect poison for interlopers.
Every few months, a plane flies laps over my place. It is the baiting plane, dropping poisonous baits into the national park that surrounds me. I'm constantly warned by letters that these dried sausage baits full of 1080 are highly attractive to dogs and cats.The last time my dog ate one from the beach below my house, it cost her a general anesthetic and probably several years of her life. Her stomach was pumped out with charcoal and I copped a two thousand dollar bill. It will kill her next time. That is the cost of living next to a national park and with a wandersome old dog who still thinks she is invincible.
Every time I hear the baiting plane droning overhead me, I hate it. I really hate that plane. I know they are doing the right thing but I still hate that plane.
I haven't got to the point about bone marrow and what it has to do with sp.gastrolobium, 1080 and dogs. So bear with me here.
In 1885, a Mr Web wrote to the Australian Advertiser (28/07/1885) about cooking up a bronze wing pigeon for breakfast and giving the dogs the wish bone. "I have just had a valuable dog poisoned by eating the breastbone of a Bronze wing pigeon." The dog had died a terrible death. "I have seen dogs die of arsenic or prussic acid but their sufferings seemed mild compared to that poisoning from the bones of the bronze wing pigeon." He then went onto the idea that the bronze wing pigeons, who feed primarily on the poison bush gastrilobium bilobum, excrete the the poison really quickly from their bodies but store it in their marrow bones. This was one of the original 1080 poisonings and it came from introduced dogs eating the marrow bones of bronze wings.
