I don’t even look at the date.

Smell, fuzziness, colour, texture. And also guts of steel and an unholy track record of dumpster diving and self sufficiency - I had to learn how to trust my senses.



Only on milk. Learned that one the hard way.

Refrigerated meat (namely poultry, don’t do red meat so idk) also mostly gets tossed after the one week mark but I have a weaker immune system. Although, living in the US I don’t like eating too much meat for that same reason.

Dry goods are fine unless there’s mold or bugs.

Everything else gets the sniff test, or only goes if there’s visible mold. ¯\_(ツ)_/¯

Only on milk.

Milk is usually good for at least a week after the sell by date.


Same thing, I don’t fuck around with milk or meat. Otherwise I try to use my best judgment. Saw someone say they threw out unopened baking powder that had expired and ngl I was a little bit horrified…

Baking powder is one that does go bad. It won’t make you sick but it will stop working. Although throwing it out without testing it is crazy. You just have to put a little into warm water and if it bubbles it is still good.

Right yeah like it won’t make you sick but you don’t know it’s off yet. Plus you could add a little bit extra if it is a bit “flat”




Even badly expired milk, like when it starts to sour and get clumps, can still useful, as you can still use them in recipes, like baking cookies and cakes

We used to make batches of farmers cheese with spoiled milk, and I think give the whey to our tomato plants. You can also then use the cheese to make syrniki which is awesome. These days we’re not buying much milk so it hasn’t come up as much.




Theres a place near me that sells products with damaged packaging as well as past the sell-by date. Prices are similar to grocery shopping in the 90s, so it’s where I buy most of the shelf-stable foods I eat. I balk at grocery store prices now, and just go without until I have time to make the hour and a half (one way) trek out there. Stuff like chips/crackers are a caution item cuz the oil starts to taste bad (still edible just not good), ultra-pasteurized milk starts to separate, and sauces can taste stale depending what they are made with (acocado and olive oil bases seem to be prone to this)

But otherwise its a great way to use food that would otherwise go to waste, they get stuff from indian and asian groceries as well so I get to try a lot of stuff I’d never otherwise buy due to being wildly expensive import stuff. And it saves a ton of money. And if you buy something for $1 and it sucks, you don’t feel bad throwing it away.

Grocery Outlet has lots of stuff close to the date for a fraction of the price of other stores. I love it. I get most of my dry groceries and a bit of my perishables there. So much better than any of the major chains.



I had an ex that would use that date to determine when to throw everything away. Drove me nuts… Use your nose or try a bite . Everything spoils differently.

Everything spoils differently.

This is where info seems to be scant.

My mother often told me: if there is mold in something with tomatoes → death.. toss it. I’m sure there is a grain of truth to that but I recently tested this. I scooped out a bit of mold from tomato sauce in left-overs, and ate the rest w/out issues. I probably reheated the left-overs but don’t exactly recall.

Heard stories about some granny unwittingly using spoiled mayonaise in potato salad served to her church which killed people. Bacteria/virus/pathogens love eggs (hence why it’s used for vaccine making). So I don’t fuck w/mayonnaise but fries vendors often have big tanks of unrefrigerated mayonnaise with hand pumps. Not quite sure why that has no issues.

In any case, it would be useful to find a reliable source on what kinds of bacteria are common in what foods, and ultimately which spoiled foods are more or less likely to cause serious issues.

How you react to eating unsafe food can depend as much on you as it does on the food. What you could eat without noticing any issue might make some other person very sick and kill yet another person. It can depend on factors like how good your immune system is feeling that day, what it has experience dealing with, how good your overall health is, and what specific species makes up your gut biome. Or, counter-intuitively, sometimes if you are less healthy overall, it can mean that something doesn’t affect you as much, eg if you have gut issues that prevent you from absorbing toxins related to some pathogen, you could pass it fine while it knocks a healthier friend of yours on their ass.

For the mayo, my guess would be the ones usually not kept in a fridge likely use more preservatives, though I’d bet they also have a shorter shelf-life than the ketchup and mustard pumps. Another possibility is that it isn’t really mayo but just something that looks and tastes like it but was made very differently.

For which bacteria is present on foods, I believe that this is very region-dependent and that the supply chain will play a bigger role than the food type (though food type will affect which bacteria and fungus species thrive on it). Might see different microbe profiles based on time of year and all of them will be evolving new clades and going extinct over time. Not sure how much of an impact survival of the fittest has on what this actually looks like from year to year or decade to decade, but understanding what microbes are doing what to your food could be a moving target similar to trying to keep track of what covid clades are associated with what symptoms or traits.




No, some things last for a long time, others don’t.

For example:

  1. We bought 3 pallets of Almond milk (by mistake! I only wanted 1) at an auction a few years ago. It is all in 1L tetrapaks, and although it went out of date in August 2024, it is still good, and we use it every day.
  2. Crisps - We have a pallet of Walkers cheese and onion crisps in “aluminium” (mylar?) bags bought at a similar time. They are still crunchy and taste fine. Some Morrisons own-brand dorito-type corn chips in normal plastic (with see-through section) bags which came in the same package, didn’t fare so well. They lasted less than a year after their BBE date.
  3. Organic Seaweed sheets - these were also packed in “aluminium” (mylar?) bags too (with moisture inhibitor “pillows”. They lasted well past their BBE date, but don’t taste nice when eaten straight from the bag - maybe this is something to do with the oil that was used (and possibly the same reason as why the “doritos” didn’t last long)?
  4. Beer - different types age differently. I don’t like beer, but I had loads of Fosters and Stella left over from a party. Both had similar BBE dates. After about a year past their BBE, the Fosters cans started frothing when opening (even though they weren’t shaken), and made my stomach feel a bit weird (I was trying to make shandies out of them as I can cope with that!). Stella Artois, on the other hand, was still fine at the same point, and for several months after.
  5. Pepperami - I ate one that was 10 years out of date. It tasted fine, and I didn’t die, which was a bonus.

I don’t risk it it with meat so much, but you can usually tell as it changes colour obviously.

As I’m trying to eat less meat and more vegan alternatives, a lot of the alternatives to sausages and burgers etc. last a long time after their BBE. Recently one vegan burger had a bit of mold on it, so I scraped it off before cooking it and it tasted fine - I wouldn’t have done that with a meat version :/

It really annoys me when people throw stuff out the day after something goes out of date. Whatever it is won’t become immediately radioactive/poisonous, are they that stupid?? grrr


… Also “often a waste”??? always a waste. People (myself included) need to get better at planning meals so there’s less food waste generally. I’m guilty of wasting food sometimes, and I get really cross with myself.


Even grocers get this wrong. I asked a grocer if I could get a mark down on beer that was past the best by date. Was told “actually I cannot sell that to you” before taking it off to the back room.

In more progressive regions, food past the date is given to charity, who then know more about the meanings of the dates and the safety tolerances.

I volunteer at a food bank, and I can tell you food past the date is given to charity is correct. However who then know more about the meanings of the dates and the safety tolerances. is wholly incorrect at our food bank. As long as there is no visible mold it is given out. If there is no way to inspect it, it is given out.

It sucks that there’s so little expertise or interest in being academic about it. Over the decades these things have been running for, there should be a database of which foods are generally fine to ignore any best by date, what specifically is best by that date and how it isn’t as good after, what to watch out for on the safety side of things, and when to not risk it.


Where I am they ask people what the source of the food is (if they did not collect the food themselves) and they inspect to the extent possible. Then if something is risky for humans but suitable enough for cats and dogs, they distribute it from a separate box or table as pet food.




Comments from other communities

I don’t remember who told me this “system” to check if food went bad, but it’s a great one imo

  1. If it looks good, smell it
  2. If it smells good, taste it
  3. If it tastes good, eat it

Yea, good advice. But also good to remember you can’t smell or taste salmonella, e coli, listeria, botulism, etc…

Of course this approach has its limits. I thought it was clear when I said that this method is to “check if food went bad”.

If something like meat has not been cooked, or a dairy product has not been properly pasteurised, or there where unsanitary food production conditions, or not canned properly etc, this method does not apply.

It is definately not a way to check if something is eadible in general. And if you are pregnant or have special diatery needs, you know the specifics of your situation.

AFAIK, you can’t visually assess whether something’s been “properly” pasteurized or canned, and plenty of traditional dishes use un/semi-cooked meats.

The saying smacks of <90s (if not <50s) in its deceptive simplicity, and assumption that the listener is smart enough to suss out the rare moments it’s applicable.

(aside: definitely*, edible*)



That is a good reminder, thank you



I would add: if it tastes off, spit it out, as tasting does not imply swallowing.

Worth noting as well that the taste test can kill you when dealing with some very toxic variaties of wild mushrooms – even if you spit it out.

Yeah, those rules don’t feel meant for foraging, just for assessing spoilage

So, they’re universal “rules” like the timeless “i before e” one, right?




Gotta be careful with cooked rice because it goes deadly in a way that’s unnoticable

I suppose, yes and no. In a way the tricky thing is to know what to look for: to be able to recognize that a slimy texture is a sign that it has gone bad.

Here are some more medically reviewd tips from healthline:

Does Rice Go Bad? Shelf Life, Expiration Date, and Safe Storage


I’ve seen refrigerated cooked rice turn pink and slimey in spots. I trash the dodgy looking stuff and fry the rest. Is that a bad idea? I got away with it twice so far. Now I leave the lid loose so some of the moisture can escape.

(edit) after reading the link posted by ‘solo’, I guess i should freeze rice if I don’t use it after a couple days.

I gotta admit I’m a bit confused because none of the articles posted here - articles made specifically to talk about if rice is safe - seem to be aware of fried rice syndrome? The thing that is such a thing that it got an own name?

The danger about fried rice syndrome is that it is unnoticeable. Meat goes bad, it stinks or gets white dots, etc. Fried rice syndrome, it doesn’t appear different at all and you can just straight up die from it. Restaurants only make rice fresh because of this danger.

But restaurants are extra careful, of course. At home, if you make sure to cool your rice quickly it’s ok. Which also means, don’t put one huge bowl of warm rice I to your fridge, because it will stay warm enough for the bacteria in the middle.

It’s also one if those things that doesn’t happen often, so there’s a chance you go through your whole life without this ever being a problem, but I don’t wanna die from bowl of rice.




They never met a wild mushroom, I assume.

Yesterday, I passed a deer chowing down on mushroom fairy ring. Not really relevant, but your mention of mushrooms reminded me.

Similarly, I was camping waaay out some years back, and discovered during pack-out that one of my magic chocolate truffles was missing. I found it by the firewood cache, but nearly half eaten, and still being gripped in one of the dead mouse’s forepaws. 🤷🏼‍♂️ Ya live & learn, or ya don’t, I guess. That little guy rejoined the cosmos in Technicolor, though! 🤗


Thank you for sharing this.





I wish I could get my bf to believe this.

Share some facts and official advise, that should convince any reasonable person. If your region doesn’t differentiate between ‘use by’ and ‘best by’ then the website lists the foods to be eztra cautious with (e.g. meat, fish, dairy)

He has a lot of anxiety about things he mentally relates to poverty. When I’m making food for us, I use my own judgment, though. :p




yogurt, cereal, UHT milk, pasta, rice, canned stuff…dried stuff…none of them expire. I once lost a yogurt (sealed) on a desktop behind some paperwork (very much not refrigerated, not advised) and once I found it a few months later…it was still good edible :D


My wife goes strictly by the date, even before sometimes. Doesn’t matter what it looks, smells, or tastes like, if it’s at the date, it gets tossed.

Some dates she makes up, like deli meat. She gives it 3 days, and it’s gone, which isy biggest irritation. Nothing worse than looking forward to a sandwich, only to find out that it all got tossed.

It’s been over 30 years, I’ve moved on from that argument. I just try to find the stuff that’s getting close, and use it up.

Guess I’d try getting a separate mini-fridge, with a lock. When something is ~2 days before triggering the chronic waste manager, move it to the locked fridge.


Clearly she’s abusive and you need to dump her ASAP.

Oh wait this isn’t r*eddit. Never mind, good job on your 30 years.



“Expiration” dates are pure marketing, 100%. They only exist to pressure stores to restock asap for more profit to the sellers’ shareholders, nothing more. 🤌🏼

They are legal requirements afaik.
