How long after the expiration date is it safe to eat Jello pudding?
You shouldn't eat Jello pudding after the expiration date because I ate it once after the expiration date and was very sick and crying like a baby!
If you are talking about a dry pudding mix, the answer might depend upon how long the pudding has been expired. There would not be a food safety issue, but the mix might have degraded in quality. If the expiration is very recent, I likely would not have a problem making it for my personal consumption.
It isn't. That's why it's called an "expiration date." Eating it past that date could be harmful, and you risk getting a disease such as E. Coli. If the food was stored properly as indicated on the package, the food is good to eat quite long after the expiration date. The expiration date is similar to a guarantee, for consumers; for example, restaurants. If you see any change in the food or are not sure…
As long as the packaging is intact and the mix itself doesn't get wet, what could really go wrong with it? Some ingredients may break down over time, affecting the taste/color, but other than that... Still, jello and instant pudding are really, really cheap, so just go buy a new box if it's more than just a little bit past its sell-by date.
