Several things:

1. As with any machine tools, always wear eye protection.

2. The shredder comes with double safety cut-off switch. It would not work if the blades are exposed. Still I am superstitious. I unplug the shredder before I have to open and clean it.

3. I do not use raw bones and meat. I only use cooked bones. There are rats, dogs, cats, possums, racoons in the area, I never have any problem in the few years I have been doing this. Maybe the bones are so finely chopped and tilled into the soil.

I have not had a soil test done, but I think I do not need to add phosphorous.
