Question about worm wee(liquid fertilizer)

I own a wormery and unfortunately most of my worms died due to me peeing on them(I'm not sadistic, just thought it was beneficial) anyway after this error I have set up the wormery from scratch and purchase a book called 'composting with worms' by George Pilkington. After reading this I have found conflicting statements. For example:

The book states that the liquid which is tapped off at the bottom is toxic to plants(However it doesn't state whether it's ok when diluted). Is this true? I have read that it's the best fertilizer you can get so I am slightly confused. It's called leachate in the book. Can anyone clear this up for me?

Secondly assuming the liquid is safe for plants once diluted is it suitable to be stored in plastic bottles with fixed lids. The reason I ask i that i've read that a lot of the beneficial microbes would die due to there not being enough oxygen. The lids are obviously not air tight so will allow for some oxygen.


I appreciate these are quite complex however if anyone could shed any light on them that would be great.

Thanks in advance
