Depends how far after the expiration date, just a short time it is probably okay. One way to tell is if the color is faded, the flavor is weak and it doesn't really smell like it used to, it is time to throw it out. If it still smells strong, tastes like cinnamon and isn't faded it should still be good.
yes, usually last about two years if kept sealed in cold dark cupboard
If the production and/or date codes are not legible, you cannot tell what the expiration date is.
They will not tell you
I'll tell you a company to buy Ceylon Cinnamon in bulk according to records Shanigs Ceylon is an Exporter of Ceylon Cinnamon from their own Factory and also try Cinnamon WorldWide, these two companies are a joint venture and hit a huge export market as at today 2011
by the expiration date, dummy
You can tell if a leg of lamb is bad by looking at the expiration date. You can also tell by the smell.
check the expiration date you could also tell by the smell
The use by date should be printed on the label (at least it is in the UK).
Smell Curdled Expiration Date Taste
Look for wierd behaviors and such, and check the expiration date just to be sure.
I don't know how to read the expiration date. Can you tell me what the code of WD7039 on the Gelatin box means.
The expiration date on most drugs tell you when the manufacturer is guaranteeing it will have the maximum potency. Taking a drug after the expiration date is taking a chance that it won't be as effective as a drug taken within the "guaranteed effective." So, in answer to your question, on the diphenhydramine, no one knows if it is safe. All you can say for sure, is the manufacturer will not guarantee the drug is 100% effective after the expiration date.
No that Means two Year out of date from when im answering this question
