Also, if you have been following this blog, you know that I moved over a year ago and have been so busy with other things that various precautions that I usually take for granted took me an embarrassingly long time to implement. One of the final things that I just got around to doing this month has been to dig my emergency supplies out of the “still to do” pile and check them. And I’m glad I did, because my canned food all had use-by dates in mid-2016. While it’s well documented that a tragically large amount of perfectly good food is thrown away due to arbitrarily chosen “use by” dates, in the case of canned food, some of these dates are real and should not be ignored.
So my negligence gave me the opportunity to run a little experiment for you all! I opened up samples of each canned good that was 1.5 years past the use-by date to see what was still good, and I’m giving you the results here. I replaced all of my canned supplies whether good or not, but I tossed the ones that were bad and I’m incorporating the ones that are still good into my current meals.
(In case it is not obvious, this was written at the very beginning of January 2019, and posted a few weeks later)
First, here are the canned goods that were still fine:
Corn (Del Monte) in water, expiration date Aug 2016: Tastes good, smells good, good crunchy texture. I’ve been snacking on it.
Whole white potatoes (Safeway), exp. June 2016: Not exciting but still fine.
Whole beets (Safeway), exp. June 2016: Perfectly fine. I’ve been snacking on them; I actually had a beet instead of a cookie the other day!
Now here are the one that I tossed but would still be ok to eat if food were limited:
Corn (Green Giant) “Steam Crisp” (packed without liquid), exp. Oct 2016: Ok, but not crisp and not sweet. Not unpleasant, but bland and boring.
Now here are the ones that I tossed because they were unpleasant:
Almonds (Blue Diamond), unsalted, cans with peel-back foil and plastic lids, exp. Aug 2016: They smelled a little off and were ballooning at the sealed foil.
Garbanzo beans / chick peas (Bush’s Best), June 2016: Smelled unpleasant.
Sliced peaches in extra light syrup (Del Monte), exp. July 2016: Good flavor, but soft and mushy.
Apricot halves in 100% juice (Safeway), exp. March 2016: Not sweet at all and somewhat bitter, completely mushy and falling apart; very unpleasant! (In fact, I waited a week to write this so that I could confirm that I did not keel over after tasting one.)
How about dog food?

Some of the wet food cans also had use-by dates of a year ago or more (I forgot to write down the dates). I did not even bother to open them; since wet dog food can smell a little odd to the human nose even when dogs love it, I would not want to guess if an extra odd smell had appeared so I just tossed them to not take any chances.
Vitamin pills: cute idea but let’s not try that again

What else can go wrong?
Then there were the other things in the kit that needed to be replaced for various reasons that were sometimes surprising. My Eton American Red Cross emergency radio in its beautiful red shell was… sticky! Very sticky! Even though it had been sitting in its box in a compartment of my emergency kit and was not to humid or hot or anything. Gross. I have ordered a new one. (Yeah, I know, “insanity is doing the same thing…” but perhaps this was a fluke; they are a reputable company. Plus, the product has been redesigned last year.)

So there you have it: not everything lasts forever. Even waiting an extra year from when you had planned to check your supplies is not a good idea. And even non-consumables can go bad as technology evolution leaves them in the dust. Now I must remember to back up this article… let’s see, where is that floppy disk drive again…?

Flavor Burst vitamins that burst - hilarious.
ReplyDeleteJust want to caution against keeping Duracell batteries in devices for years, because they often leak. Not sure if that's because of all the fakes on the market, but i've switched to GP Recyko rechargeables, which i recommend. They have a slow self-discharge rate like the esteemed Eneloops, but with fewer fakes since they're not as common. I check on them every 6 months, and have had no problems after 4 years.
Thanks Jeff. Yes, keeping alkaline batteries in devices for a long time can lead to leakage that can mess up the device also; I've had more than my fair share of that over the years. Batteries are best stored just in their package. I did note however that in regard to the lithium AA, AAA, and CR123 batteries, the Energizer website claims they will not leak; more info is at that article (it has a link near the beginning of this article).
ReplyDeleteWe have food from the '90s. Some are MREs in a liquid state in green mylar. Chuck em?
ReplyDeleteGood question and hard to answer just by the description. I haven't seen MREs in green mylar so I am not sure which they are. I would refer you to the earlier article on the topic at http://quaketips.blogspot.com/2013/10/mre-shelf-life-follow-up-ever-wonder.html and you could try opening one and assessing it directly visually and by the smell test... If it's vile, you'll probably know it! I can't guarantee anything though, of course.
DeleteThere's also the point that while it's interesting to know how far back one can go, there is presumably a point at which they just are unpleasant to eat. If I have gotten to twice the anticipated shelf life (long end of the estimate), I might just not keep them longer than that, but it is going to come down to the specifics of your exact situation.
