YES, but only if you have sever Allergies to mold or yeast in which case you shouldn't be eating them anyways. The age of the product has no effect on its safety if it was in a sealed original package, since without air the yeast can not activate and the mold spore will never grow.
The only documented case was from a 19 year old that ate two pancakes made from a mix that had been left open for over two years. His companions all stopped after one bite because they didn't taste right ,but he finished off his stack of pancakes. He had a history of Asthma and severe mold allergies.
No
If you are using the yeast in bread, then if it is expired it may be dead and your bread will not rise. You could make a sponge of the yeast by mixing it with warm (not hot) water and wheat flour; if the sponge becomes foamy, your yeast is fine to use. If you are eating it as a dietary supplement it depends on the form. If it is in a dry form, it probably is okay if it is slightly expired. If it is in a wet form, if the yeast is dead then harmful organisms may replace it and it should probably be discarded.
yes
yes, some yeast extracts do have live spores in but they cannot cause infections because they are harmless spores. hope you find this useful from abi age 13
a few examples could be:Death Cap mushroom and psylocybe mushroom, are both dangerous to humans.Some yeast is dangerous to many species.Mold spores can be harmful to many organisms.
-- carbon dioxide -- alcohol, if not attended to -- spores to make more yeast, if properly cared for
No Yeast cells produce spores which serve the same function as seeds
is yeast dangerous or harmful
They are produced by the yeasts where they are growing and living.

Yes yeast reproduce by this.
If you use an expired yeast infection cream just discontinue use and get a new cream. It's unlikely to cause you any problems so no need to worry about having used the expired cream.
