The only thing that I truly KNOW about potatoes is they cannot be stored with onions, as the both produce a gas that causes each other to rot. Usually before anyone gets the opportunity to be sick, a rotting smell will be emitted, causing you to do a thorough search to find the smell. I have never heard of anyone getting sick from potatoes, other than the one cleaning up the mess vomiting from the smell.It is putrid.
You'll have to rely on your Dr's advice on your son's illness. Cleanliness is always a plus when dealing with children and flies can spread filth.
I have heard and read that the sprouts from potatoes are mildly (or maybe more than mildly) poisonous. I have never known how deep into the potato the toxin could go. But if the potatoes you mention were sprouting (rather than rotting), and if whoever prepared them did not trim away enough of the sprout, then that might cause some sickness.
However, I personally don't believe that it would be a three-week long sickness, but possibly something more like food poisoning. That is just my opinion and not based on any actual medical knowledge about potatoes and sickness. Your very best bet is to tell and ask the doctor about it, as Sweetsusieg wrote.
The smell of rotting potatoes is indeed one of the worst ones that can happen inside anyone's kitchen.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
