In Queensland, Australia, my friend had a hunting property along the 'Dingo Fence", and discovered that the local council dropped 1080 Dingo baits by air onto his property, and he was sent the bill, which is another story in itself.
Either way, he had a large population of Lace Monitors (Goannas) on his property, which were a pest, and I am guessing ate the baits. But I never found dead goannas, which was strange, until read an article in a hunting magazine stating that Goannas could eat up to 70 x 1080 baits before passing away.
Honestly, I have never eaten Goanna, and I was interested until I read the 1080 article. 1080 accumulates in bodies, so I am guessing if I eat one, it will be instant death ???
Honestly, the 'First Australians' are the only people who can officially eat protected species, so I do recommend them to check out the local bait laying zones before going walkabout. Same too with any future survivalists.
