Are the white things on a bread normal? I have a piece of olive bread which was good by April 16. I have seen some white things on them since I got them on April 17, and have kept it in refrigerator. Are they normal and safe to eat?

Will it make it safer to eat by boiling the bread?

Thanks.

From what I can tell from the picture, most of the white stuff is flour; it was likely like that when you bought it, but only you &amp; your memory know for sure. The non-bread &amp; non-white occasional spots in the picture appear to be the olives.

Overall, unless you spot obvious mold, which is more often green than white, I think you are OK to consume it. But it's nearly a week past its date, so I'd consume it soon.
