Just read in the paper that a woman killed her 4-year old stepchild by making her eat too much salt: Apparently, the two were preparing a pudding, and the child accidentally put in two table-spoons of salt instead of sugar. The stepmother got angry and forced the child to eat the pudding. The child died in intensive care a day later. Apparently, a court now ruled that the stepmother does not have to go to jail, because it is not general knowledge that excessive salt-consumption is fatal, so the death was considered accidental / negligent behavior.
The newspaper says that consuming more than 1 g of salt per 1 kg of body weight within a short span of time is usually fatal. Any of our natural science / medicine buffs can confirm this? It's total news to me!
