Purchasing Bread From Non-Muslim Bakeries

We, as Muslims, should refrain from purchasing food items prepared in non-Muslim outlets, particularly when they sell other Haraam food items as well, due to the fear of contamination with Haraam ingredients.

It is recorded in a Hadith:

Hadrat Naumaan Bin Basheer Radiallahu Anhu says that, ‘ I heard Rasulullah Salallahu Alaihi Wasallam saying – Nu’maan indicated towards his ears-, “Verily Halaal is clear and Haraam is clear, and in between them are doubtful things which most of the people are unaware of. The one who refrains from doubtful things will protect his Deen, whilst the one who falls into doubtful things will fall into Haraam.

From the above Hadith, we clearly understand the importance of consuming Halaal and refraining from Haraam and doubtful things.

Yes, if there is certification from a reliable Halaal authority, then there will be no harm in purchasing it.
