> There's no way a child would accidentally manage that, for example (even assuming LD for a child is much lower). But I couldn't find specific numbers for seeds.

My partner was worried when we moved into our current house that our then-18-month-old son would eat the poisonous cotoneaster berries on the bush in the garden.

But it turns out the LD50 is something like 50g/kg which means that even for a 12kg child they'd be eating huge heaping bowlfuls of them before anything happened.

As it turns out, he did eat one of the cotoneaster berries, spat it out, and went looking for some of the far nicer tasting alpine strawberries instead. The cotoneaster berries taste quite particularly horrible, and no-one is going to ever eat even close to the LD50 of them.
