## Food Storage Shelf Life Chart

Store-bought cans keep their best quality for two to five years, flour, oil and other cupboard staples for months, and dry staples sealed without oxygen for 30 years or more. Here is the chart, with the sources behind each number.

By Ruth Calloway, November 10, 2026

Store-bought cans hold their best quality for years, longest for meat and vegetables, home-canned jars for about a year, and everyday pantry goods like flour, oil and peanut butter for six months to a year. Dry, low-fat staples such as wheat, white rice, dry beans, rolled oats and pasta last 30 years or more once they are sealed away from oxygen and kept cool.

Those numbers describe quality under decent storage, which in most homes means a closet or basement rather than a garage. Every figure below comes from a university extension service, Brigham Young University's long-term storage research, or the USDA, with a link to each. Use the chart to decide what belongs in the pantry you cook from and what belongs in the sealed layer you hope never to open.

### A best-by date measures quality

The date stamped on a can or a box of pasta is the maker's estimate of when the food will taste and look its best. The USDA's Food Safety and Inspection Service says in its [guide to food product dating](https://www.fsis.usda.gov/sites/default/files/media%5Ffile/2020-08/Food-Product-Dating.pdf) that a "Best if Used By" date indicates peak flavor or quality and is not a food safety date. Food can be sold, donated and eaten past it. Infant formula is the one exception, because federal rules tie its use-by date to the nutrients printed on the label.

For a household building a supply, that changes how you read your shelves. A can three months past its date is still good food, and throwing it out wastes money you could have spent on more depth. What the date does tell you is the order to eat things in. The closer an item is to its date, the sooner it should go into a regular meal and be replaced at the back of the shelf.

Safety comes from the package. A sound seal keeps bacteria out, and the rules for judging a seal are further down this page.

### How long does canned food last?

Utah State University Extension's fact sheet on [storing canned goods](https://extension.usu.edu/preserve-the-harvest/research/storing-canned-goods.php) puts it plainly. Commercially canned food should keep its best quality until the code date on the can, which is usually two to five years from the day it was made. For emergency storage, the same sheet says factory cans and jars remain safe to eat as long as the seal has not been broken, though the quality will not hold that long.

Acid is what separates the short end of that range from the long end. Tomatoes, fruit, juice and pickles are high-acid foods, and over time the acid works on the can lining and the food softens and darkens. Washington State University Extension gives high-acid cans [12 to 18 months](https://news.cahnrs.wsu.edu/?p=9488) of best quality, while low-acid cans such as meat, stews and most vegetables sit at the long end of the range.

| Canned food      | Best quality |
| ---------------- | ------------ |
| Fruit, tomatoes  | 12-18 months |
| Meat, vegetables | 2-5 years    |
| Home-canned jars | 1 year       |
| Retort pouches   | 8-10 years   |

Home-canned food gets a shorter window. USU says unopened home-canned jars have a shelf life of one year and should be used before two. Its authors also say commercial canners control quality and safety more closely than a home kitchen can, so commercial cans are the better choice for a supply meant to sit. Home canning is still worth doing for a garden harvest, as long as it follows a tested recipe. Our page on [old canning methods that are no longer safe](/old-ways/is-open-kettle-canning-safe) covers the shortcuts that cause trouble.

Foil retort pouches, the kind military rations come in, carry their own best-by date. USU notes the longest tested life for that packaging is 8 to 10 years and advises against counting on more.

Nutrition holds up better than most people expect. Minerals stay in canned food for its whole life. Vitamins A and C are the ones that fade, and USU puts their loss at 5 to 20 percent a year once the food is in the can. Other vitamins stay close to fresh levels. A five-year-old can of green beans still feeds you, and some fresh produce, sprouts or a vitamin C supplement can cover the gap in a long emergency.

### Foods that last 25 years or more

The longest-lived foods in any storage plan are dry, low in oil and sealed. The Church of Jesus Christ of Latter-day Saints, which has run home storage centers for decades, publishes a chart of "life-sustaining" shelf lives drawn from BYU's taste studies in its [guide to long-term food storage](https://www.churchofjesuschrist.org/study/manual/emergency-preparedness/01-food-and-water-storage/03-long-term-food-and-water-storage?lang=eng). The figures assume the food is properly packaged, at roughly 10 percent moisture or less, and kept at 75 degrees Fahrenheit or cooler.

| Sealed staple | Life-sustaining |
| ------------- | --------------- |
| Wheat         | 30+ years       |
| White rice    | 30+ years       |
| Dry corn      | 30+ years       |
| Pinto beans   | 30 years        |
| Rolled oats   | 30 years        |
| Pasta         | 30 years        |
| Potato flakes | 30 years        |
| Apple slices  | 30 years        |
| Dry milk      | 20 years        |
| Dried carrots | 10 years        |
| White sugar   | Indefinite      |

"Life-sustaining" is a deliberate phrase. BYU's panels tasted food that had been stored for decades and asked whether people would eat it in an emergency. Oscar Pike, who led that research, told [BYU Magazine](https://magazine.byu.edu/article/ask-an-expert-new-tips-for-old-food) that wheat and white rice were still very acceptable after more than 30 years. That is a long way from fresh, and a 30-year-old bean takes far longer to cook than a new one, but it is real food.

The packaging decides whether you get those years. The Church guide recommends foil pouches and PETE bottles with an oxygen absorber in each, and says food-grade buckets with gasketed lids work for wheat, dry beans and other dry goods unlikely to go rancid. Our step-by-step guide to [packing rice, beans and wheat to last 30 years](/food-storage/pack-rice-beans-wheat-for-decades) covers bags, buckets, absorbers and sealing in detail.

Dry milk sits at 20 years and dehydrated carrots at 10, which is a useful reminder that "freeze-dried" or "dehydrated" on a label does not put a food in the 30-year column. Pre-packed emergency meals carry their own dates from the maker, and those dates are the ones to plan around.

### The everyday pantry: months

Most of what sits in a kitchen cupboard keeps for months. Extension guides put these items in the range below, unopened, at room temperature:

| Pantry item   | Unopened    |
| ------------- | ----------- |
| White flour   | 6-8 months  |
| Peanut butter | 6-9 months  |
| Vegetable oil | 6-12 months |

The first two figures come from the University of Arkansas Cooperative Extension Service's [storage guidelines](https://www.uaex.uada.edu/counties/miller/STORAGE%20GUIDELINES%202013.pdf), and the oil range from the University of Kentucky Cooperative Extension. North Dakota State University Extension gives oil a tighter six months in its [pantry storage chart](https://www.ndsu.edu/agriculture/sites/default/files/2023-01/fn579.pdf).

What these foods share is fat, or the oil-rich germ of the grain. Fat oxidizes, and rancid oil smells like old crayons or paint long before it would make anyone sick. That is why cooking oil, which every long-term plan needs for calories, has to be bought in amounts you can use within a year and rotated through your regular cooking. The Church guide adds that oil and anything stored in clear plastic bottles should be kept out of light.

White flour sits in the middle. Milling exposes far more of the grain to air than a whole kernel does, which is why whole wheat berries last decades and the flour made from them lasts months. A hand grain mill turns a stored bucket of wheat into fresh flour when you need it.

### Dry foods that fail in a bucket

Some foods look dry and shelf-stable yet spoil within a few years once sealed away. The Church guide names the dry products it does not recommend for long-term storage:

* Brown rice, whole wheat flour, pearled barley and milled grains other than rolled oats
* Nuts, granola and chocolate
* Dried eggs and dried meat such as jerky
* Bottled or canned butter
* Brown sugar
* Home-dehydrated fruit and vegetables unless they are dry enough to snap when bent

Most of that list goes rancid because of its oil. Jerky, soft dried fruit and brown sugar carry moisture, and moisture in an oxygen-free container is dangerous. The Church guide and USU both warn that botulism poisoning may result if moist products are stored in packaging that reduces oxygen, so these foods go in the rotating pantry or the freezer.

### Heat sets the clock on every number

A shelf-life chart quietly assumes a cool room. USU Extension's [food storage guidance](https://extension.usu.edu/news%5Fsections/home%5Ffamily%5Fand%5Ffood/get%5Fthe%5Fmost%5Fof%5Ffood%5Fstorage) cites USDA figures that shelf life is cut in half for roughly every 10.8 degrees Fahrenheit of temperature rise, and recommends a steady 40 to 60 degrees. The Church guide sets 75 degrees as the ceiling for its 30-year estimates and says to rotate faster when storage runs warmer.

Each step of about 11 degrees warmer cuts the expected storage life roughly in half.

Run that rule forward and the location matters as much as the food. A bucket kept at 60 degrees has about four times the life of the same bucket in a space that sits near 82 degrees, and an attic or garage in a southern summer runs hotter still. Cans suffer from cold too: USU says never to let sealed cans or jars freeze, because freezing leads to rust, burst cans and broken seals.

The best spots in most houses are a basement wall away from the furnace and water heater, interior closets, and the space under beds. Keep every container off bare concrete. USU says moisture wicks up from the floor into cans and starts rust, and the Church guide asks for at least half an inch of air under buckets and no more than three buckets in a stack.

### Reading a can or jar before you eat it

Old stock is judged by its container first and its contents second. USU's canned goods sheet gives a sequence worth following every time you pull something from the back of the shelf:

1. Before opening, throw out any badly dented, bulging, rusty or leaking can, and any jar with a broken seal.
2. Open it and look and smell. Discard any can that spurts when opened, and anything with a strange odor or appearance, without tasting it.
3. If it looks and smells right, taste a little. For older cans, USU suggests boiling the food for 10 minutes before tasting.
4. Heat low-acid foods such as meat and vegetables to 165 degrees, or boil them for 5 to 10 minutes, before eating.

Some changes look alarming and are harmless. USU lists darkened color, soft texture, glassy crystals in canned fish and white crystals in fruit like apricots as safe, and food sitting above the liquid line in a home-canned jar as safe too. [Ready.gov](https://www.ready.gov/food) repeats the core rule for emergencies: do not eat from swollen, dented or corroded cans.

Once open, a can is ordinary perishable food. USU gives opened canned goods a day to a week depending on the food, and says to move high-acid leftovers out of the can into a covered dish so they do not pick up a metallic taste.

### Rotation keeps the chart honest

Every number on this page assumes the oldest food gets eaten first. USU recommends writing the month and year of purchase on each can lid in marker and using first in, first out. That habit is what lets a household carry six months of canned food without ever throwing a can away.

The Church's own approach splits a supply into two layers. The three-month supply is the food your family normally eats, bought a little extra each week and rotated through meals. The long-term layer is the sealed staples, which sit untouched for years. That split lines up neatly with this chart: the months-and-years foods live in the pantry and turn over, and the 30-year foods go in buckets and stay put. If you are still working out how much of each to keep, our guide to [three months of food for a family of four](/food-storage/how-much-food-to-store-for-a-family-of-four) does the arithmetic.

A simple shelf layout helps. Load new cans from the back or the top and take from the front, so the shelf itself enforces the rotation when the person restocking is in a hurry. Label buckets on the lid and the side with the food, the packing date and the absorber size. When you open a long-term bucket to cook from, move what is left into a smaller container you will finish within a few months.

Food is only half of the calculation. Rice, beans and pasta all need water to cook, and our page on [how much water to store per person](/water/how-much-water-to-store-per-person) covers the extra gallons a storage diet takes.

### My take: how I'd use this chart

I'd sort a household's food into three shelves before buying anything new. Canned meat, vegetables and soups go on the first, rotated through weekly meals, because their code dates leave room enough to build a few months of depth without waste. Oil, flour and nut butters go on the second, bought in amounts the family will finish inside a year. White rice, wheat, pinto beans, oats and pasta go into sealed buckets on the third, and that is the shelf I'd grow once the first two are steady.

I'd skip stocking up on high-acid cans beyond what you eat in a year and a half, and I'd hold off on bulk brown rice and nuts however good the price looks. Above all I'd spend the first effort on the room, moving storage out of the garage and into the coolest part of the house, because heat shortens every line on the chart at once.

### Questions about shelf life

Is canned food safe after the best-by date? 

Usually, yes. A commercial can with a sound seal stays safe well past its code date. What fades is flavor, texture and some vitamins, so eat the oldest cans first and throw out any that bulge, leak, spurt or smell wrong.

Does freezing extend the life of canned goods? 

No. A frozen can may rust, burst or break its seal, and the food comes out mushy. Keep cans above freezing and below about 75 degrees.

What food lasts longest without any special packing? 

White sugar, salt and baking soda. Kept dry, they do not spoil, which is why the Church chart lists sugar as indefinite. Honey and hard liquor keep a very long time too.

Can I store brown rice or whole wheat flour for years? 

Plan on months. Both carry the oily part of the grain, which goes rancid. Store whole wheat berries and white rice for the long term, then grind or buy the other two as you need them.

How should I write dates on my storage? 

Mark the month and year you bought or packed each can, jar or bucket in thick marker on the lid, where you can read it without pulling the item off the shelf. Then put new stock at the back so the oldest is always in front.
