Can mold be in the middle of the bread?

Yes, mold can grow in the middle of bread, although it's more commonly seen on the surface. Bread is often stored in a way that allows moisture to accumulate, creating an environment conducive to mold growth. If you notice mold on any part of the bread, it's best to discard the entire loaf, as mold can penetrate deeper than what is visible. Eating moldy bread can pose health risks, so it's safer to avoid it altogether.
