This should help clear it up for you.

IIRC, the irritant lies within the oils in the wood itself. They don't go away with time either.
Meaning, the dust remains "toxic" for years. When I work with Cocobolo, I work in full
sleeves, a respirator, a full face shield, goggles, long pants, socks & shoes, gloves, and
a thin skull cap to keep it out of my hair. A painter's hood will work too.
If I had a haz-mat suit, I'd wear it too.
I try to work with it outside if I'm cutting it.
If I'm turning it, I make sure to vacuum up all the dust as soon as I'm finished.
I try not to track the dust all thru the house as well.
I do not own a dust collector or a filter unit, those are on the wish list.
If you have one, use it.
I make sure to throw away any used sandpaper, stirring up as little dust as possible.
I wipe down my tools with rubbing alcohol after turning it too.
Ideally, you should blast any dust off yourself with compressed air outside before going back in the house.
By now, you've probably heard the phrase :
"There are 2 types of people. Those who are allergic to Cocobolo, and those who will be allergic to Cocobolo."
I have found that to be true. The allergies to it are accumulative.
You might start out with a mild rash the first few times you use it, and after that it just gets worse & worse.
Breathing problems, eye irritation, severe rashes, and even blisters are other reactions.
The link I provided above will add some info I have not touched on here.
As for finished articles, it is generally safe IF it has a finish on it.
I would not use any bowls or spoons made from it for anything
other than a display.
I hope this helps someone.
