Hi, @marynn. Yes, I've heard of people dying because of that poisoning.
BTW. I noticed that you have several sentences taken from other websites. If you don't quote them properly, you risk running into plagiarism. Also, it's not advisable to quote such a long text. In that was the case, it would make more sense to visit the site and read from it directly.
Thanks so much, I will read through my work and make necessary amendment.
