Personal opinion, and I wouldn't ask anyone else to follow it, but I believe that my outdoor, buried worm buckets get rid of everything.

I throw all my kitchen scraps in there. They are a bacteria and small bug breeding ground. The worms eat and live in all of it.

What comes out of there is so completely processed by worms and bacteria and fungus. I'm not really scared of anything that isn't the natural culture that lives there.

Well processed worm castings are all worm poop. They process bacteria as food.

My opinion and it has been holding true for ~7 years, no matter how many day old chicken scraps I have thrown in.

Just my take on it.
