More powderpost beetle questions
A few weeks ago, I discovered what I believe are powderpost beetle signs in some live-edge black walnut I have. I wanted to make a few cutting boards and serving trays out of some of it. After some advice from Scott Smith, I built a small simple kiln, which after some trial and error, I can get to 150F, so I should be able to sterilize the wood. But this begs the question: would the wood be safe for food contact after it is sterilized? I mean, the bugs will be dead but just because they aren't alive doesn't necessarily mean the wood is safe. I may be overthinking this but I'd like some feedback from anyone with experience or knowledge on the subject.
I wanted to avoid a chemical approach anyway
As suggested, my concern about a chemical treatment was based on the food contact of the final product.
I finished some of the pieces. A few look great. On two of them, the insect damage is more prominent than I anticipated. The finish (mineral oil with paraffin wax) brought the damage out a little bit visually. I'm not sure how I feel about the look...
