You wouldn't use mait on mains water fittings, don't believe it is for use on potable water but it's a non setting putty and wouldn't be of any real use on water fittings under pressure. Boss white would be the other one as a joint sealant but that isn't for use on potable supplies either.
I only ask as the neighbour has just had his kitchen refitted and there seems to be some on his cold water compression fittings. and my kitchen was fitted around the same time
Probably best asking the installer what was used. Could be Fernox LS-X, water hawk or any other branded potable water approved paste. If it’s not then that could be against water regulations.

'Boss White' was used for years on pipework to aid jointing, and avoid leaks, whilst it's no longer allowed to be used on Potable Water, (need 'Boss Green'), I think it would take an awful lot to make you ill, and the water would taste rather funny anyway.
In real terms, what little may have been used that could of come into contact with water would have washed away quite quickly after installation, I really wouldn't worry about it after any length of time.
Bet there's a lot more in your life to worry about than your potable water... It's one of the few things that are still reasonably and regularly checked for wholesomeness!
