It varies on multiple factors.
To begin, discussing the visible look of the mould.
There is commonly 3 visible colours of mold that rests on our bread. sometimesnit can be just 1 colour. sometimes it can be 2 or 3. some have complained of multiple colours.
the three common colours consumers are generally aware of:
1 . green (as far awareness goes, this is safe unless you have Allergies) common side effects are bloating and diahhrea which usually passes within 24hrs. sometimes 48 hours. (green mold hosts a minimal risk on bread, provided you dont eat if its been left to migrate and multiply itself over 2 or more days.
2. white (this is basically the same as a yellow or amber alert for a lot of threat risk potential). 30% of consumers will commonly suffer with diahhrea, bloating, fever, and/or vomiting. this mold has a lot of contaminent spores. it is still however edible and not life threatening unless the consumer has a lower than usual immune system. When stated edible. the consumer should be safe provided it is a sandwich from mold that has only become slightly visible on the bread itself. any more than just specs and the consumer may need to hug a bowl for a day to even 4 days varying.
3. black (this has a red code for health risk) Black mold, whether it be found on food or objects around the home, is highly contaminated with dangerous spores and toxins. just breathing near this mould can affect and INFECT any animals lungs. other organs such as kidneys, bladder, intestines will also suffer from this mold. breathing it is toxic enough. Eating it... is life threatening. he consumer could fins themselves curled up into a ball... crawling to the loo or worse, collapsing and becoming unconscious... if someone believes they have consumed black mould. call your local doctor/practitioner immediately for advise... if unable to contact the local services. the consumer should contact the out of hours services. in the United Kingdom. this will either be 111 (local service for east midlands and east yorkshire region) or nhs direct. in the United States or Canada... (please add numbers as i do not know them)
Other factors
a) the legnth of time the mould has been visible and potentially growing (going by 12hr intervals up to 3 days.... after 3 days it is safer to throw it away. by this point more than a quarter of the bread would be visibly mouldy and this is in no safe criteria whatsoever)
b) the damp feel of the bred by the consumers own hand (how soggy the bread is)
c) the temperature the bread has been left sitting with (anything higher than 20 degrees and the mould can develop at a harmfully alarming pace)
d) the smell (dont attempt to smell any form of mould. fungal/bacterial pneumonia can be caught this way along with other life threatening illnesses) basically if you open the loaf and the vapours are like a slap in the face. get rid of the loaf immediately without even looking at it.
NO while in most cases it will not seriously harm you, multi grain and rye breads can make you very ill if eaten when moldy. Plain old white bread with a small spot of mold may not have any effect but why take a chance. Best to buy or make fresh and feed the birds with the old stuff.
Yes. Molding bread does have a particular odor . . . and flavor.
No. Don't eat bread that smells moldy. Sometimes you can smell it before you see it.
Yes, any stale bread that has gone mouldy should be disregarded and binned.
no... it just matters where the bread is and what happened to the bread to make it moldy
* Moldy Bread -- Not Just the old Moldy Bread You Know * Trust the Crust?

Bread going moldy is a chemical change
No. I have baked bread for 5 years and beer has the bread gone moldy - dry yes, but not moldy.
Bread is frozen to prevent it from getting moldy as it would if left in the open.
The peasants ate moldy bread because it was a kind of medicine.
that i know of no moldy bread doesnt harm birds.
The moldy bread produces Penacilin which can be used to aide against infections.

Throw it away.
Bread can get moldy quite quickly if it is in a dark area.
