Here’s the first one I found by searching. There were several more. And the recall in the news right now is for frozen waffles, which contain no meat. I never said cut fruit was dangerous. I said it is more likely to be contaminated than uncut fruit.
I read through your post a few times and it seems like you want the option to use your Persistent storage or just use the stick as a default install live boot medium.
If so, have you thought about using any of the live usbs with persistence and just make multiple users. One where persistence is used and encrypted and one that does not have access to the Persistent partition?
