@Dinosaur 1080 is an acute poison. It does not accumulate in the body. A non lethal dose may cause sickness and be passed with faeces etc.
A chronic poison my build up in the system.
1080 poison Sodium flouroacetate is naturally occurring in many Australian native plants and most native animals have tolerance to it.
Foxes and dogs have very little tolerance.
Your friend probably has a bio security obligation for the property. It is law just like if you want to drive obey the rules, if you own a house pay rates or if you have. Property control pests. I would think he would be notified if they were expecting. Contribution toward a broadscale program. Let’s not get into that one.
Scientists work out what Lethal dose Is to kill a type of animal to effectively kill 50% of a tested simple 100% of the time. That is a LD50, Lethal dose 50. From that they set a rate of dose for a bait expecting to kill a target animal .
A fox bait has .1ml injected in a fresh bait containing 3mg of active ingredient. A dog bait is double. A pig bait is generally a commercially manufactured long life bait with 72mg of active.
The poison we use is a synthesised version manufactured in the U.S where they do no they use it. It is imported by companies in Australia for distribution or preparation. The science is no secret it could be produced by the same people importing it. Scientists.
Most animals would show symptoms within a few hours and likely dead within 6 after consuming a lethal dose. There are distance restrictions and rate of laying for baiting that are set to eliminate cache in general by individual animals or multiple baits being taken by non target animals like Quolls or Goannas.
It breaks down readily in the environment etc.
There are recorded incidents of accidentally poisoning of humans that resulted in death. The short version is that you would need to eat a lot of unpalatable baits to succumb from poisoning of 1080 or have access to the restricted 1080 concentrate.
G'day CBH
Thank you for your generous, and informative, response, the 1080 information that I read was in a popular at the time in an Australian shooting magazine article, one of the regular writers with his own monthly page wrote the article. His article appeared to me to be of a scientific nature, and I assumed it to be correct, and I now realise that I have been misinformed, therefore I apologise to all the viewers of this site about quoting incorrect info.
Honestly I hate poison baiting, and the original article I mentioned turned me against 1080. Yes, sometimes there is no other option but poisoning, as it can be the only safe measure. But, I even felt guilty when I had to poison mice and rats with bait, as I had no other suitable option to dispose of them at the time.
By the way, you mentioned my friend having a Bio security obligation with the laying of aerial baits, along the dingo fence, yes, you are totally correct there, the local council were doing this legally.
It was just one of the hidden things that pop up out of nowhere when being a new landholder, mining rights beneath your land, together with miner's access rights, being another. A farmer I used to know had huge acreage between Lightning Ridge and the Queensland border. He had a lot of his property dug up by opal miners, the farmer said that it was totally legal for the miners to do so.
CBH, once again, thank you for thoroughly filling me in on the 1080, your notes are extremely interesting, especially when you mentioned that 1080 breaks down readily in the environment, that is a definite plus.
