Spent grain for fishing?

[storm in a teacup]

I'm just about to start my summer prebaiting campaign and I was wondering if the spent grain from my brewday could be used as a particle? would I have to give it a further cooking period to swell the grains for fish safety or are they cooked enough? Is it even worth the trouble.

Has anyone ever tried it?

I bake them as dog treats (20 mins at gas mark 6 and then a few hours on S to dry them out) and people use them after mashing as chicken feed. Can't see why it would matter, someone may know more but with those uses it can't be dangerous.

Stew them if you want to feed them whole or grind them up into paste and add to some crumb, they'll work!
