Never went mouldy

I got these to try a while ago as they were new, on sale, and I got bonus points.
They weren't bad, definitely extra soft, but my problem comes a few weeks later. I hadn't eaten one of the bagels and it was forgotten in my cupboard. It never grew any mould. Which is concerning....everything other bread product grows mould after that long in there. I just wanted to share that issue, I don't know how big of a problem that is, but I definitely won't be eating any more of them.
