Can a fruit tree growing beside a septic tank be contaminated by human pathogens? I have friends who got sick after eating a ripe jackfruit, which was harvested directly from the tree growing beside a functional septic tank. (It was the tree's first ripe fruit if I'm not mistaken.)
All five of them experienced diarrhea an hour or so after eating the fruit and it persisted for about a day or two. One of the five started vomiting and would no longer eat or drink so he was admitted to the hospital. He was diagnosed with amoeba.
Well this sounds silly, but, is the tree contaminated with amoeba? Don't plant roots filter pathogens? Because if the tree is really contaminated, its fruit won't be safe to eat and should be cut down. But I don't have adequate knowledge of gardening so I would like to be enlightened before jumping into conclusions.
