I have some very old brewers yeast in the pantry and was wondering if it was still ok to use for my ducklings, or if it has lost all its nutrients. Thanks
I'm sorry I don't really know. Taste it yourself and see if you can tell if its gone rancid...I don't know if brewers yeast can go rancid but it probably can lose some nutrients. If it doesn't taste or smell bad and it's been stored in a cool dry place, the stuff is probably fine. It may not have as much nutrition as it had when freshest, but it probably won't hurt anything. Give them a sample and see if they like it.
