I never thought about the tenderizer properties of pineapple being a risk to worms, but it makes so much sense!
I'm not in a place to be able to house a worm bin just yet, but it is something I have thought about for a while now. This has a lot of good info, thank you.
I have doubts about the pineapple one, on YouTube there is a guy who did and experiment and fed his worms a lot of pineapple and they were all fine and were all over the fruit.
