Food-grade buckets are one of the top three containers for DIY emergency food storage, but buckets alone are insufficient for storing most dry foods for decades.
We can’t talk about using buckets for food storage without mentioning Mylar bags and oxygen absorbers. Buckets are only part of the container solution for maximum emergency food shelf-life.
Emergency Food stored in 5-gallon food-grade buckets has a shelf life of 2 to 5 years with the exception of salt, sugar, and honey which last indefinitely. Dry staple foods like dried beans, polished white rice, rolled oats and wheat will store for two to five years in just a bucket and thirty or more years if buckets are lined with Mylar bags and treated with oxygen absorbers.
It’s good to know that the plastic in a bucket is not an oxygen barrier so food will spoil quicker via oxidation and, bugs eggs and pupae may not be irradiated so they can spoil your food.
Salt and Sugar will store indefinitely in just a plastic bucket because they are not affected by degradation via oxidation or the transfer of oxygen in and out of the bucket.
Removal of…oxygen in food is crucial to provide extended shelf-life of foods that may become deteriorated through enzymatic, microbiological and biochemical mechanisms“Oxygen Absorbers In Food Preservation,” Simon Angelo Cochello, La Trobe University, Victoria Australia
Let’s take a look at Emergency foods commonly stored for long-term survival.
Shelf Life Emergency Food In A Bucket
If stored in buckets most of the suggested emergency foods in the list below will last twenty to thirty years.
The LDS church suggests storing 400 pounds of dry staple food, “starvation food” for each individual in your family or survival group for a year’s supply.
The backbone of my survival pantry is hard white wheat, polished long-grain white rice, dry pinto, and black beans, and rolled oats. Stored properly, in buckets, these foods will last 30 years in storage without rotation.

The Downside of Buckets For Food Storage
Food stored in 5-gallon storage buckets without using Mylar bags and Oxygen absorber(s) will not last as long and has a higher chance of going bad before maximum shelf- life is attained.
Salt and sugar are the acceptions.
How Long Will Food Last In A Bucket
Why Buckets aren’t Enough Protection For Shelf LIfe
Two of the main elements that kill food in long-term storage are oxygen and moisture, and buckets don’t do a great job of protecting food from either element.
The plastic in food-grade buckets is not actual oxygen or moisture barrier, and oxygen and moisture will enter a 5-gallon bucket at some point over 30 years and degrade your food.
Plastic lids have spotty construction and tend to leak at some point.
Buckets stored for 30+ years are inevitably damaged. You might not see cracks, but air will get in. Sealed Mylar bags act as redundancy in protecting food in long-term storage.
Grains and flours: wheat, white rice, rolled oats, dried beans, and other hard and soft grains have dormant bug eggs that will hatch under the right conditions.
Killing bugs, eggs, and pupae are one reason grains are repackaged into oxygen-free storage.
Experiments were conducted to determine how long the oxygen content of 5 gal buckets filled with wheat could be held below 1% when various numbers of oxygen absorber packets were packaged with the wheat. Although it was possible to use oxygen absorbers to reduce the oxygen level below 1% for 12 d, this treatment was shown to be an unreliable disinfesting [kill bugs] method because the oxygen levels in the samples exceed 1% too frequently.Ogden, Lynn V. and Griffin, C., “Can Grain Be Disinfested In 5-Gal HDPE Buckets Containing Oxygen Absorber Packets?” (2010). Faculty Publications. 91.
If oxygen gets into a food storage bucket, the bugs don’t die, and they multiply. The stored food becomes a nursery and outhouse for weevils and other pantry pests.

The Upside of Food-grade Buckets for Shelf Life
Buckets are part of a super-storage trifecta, the perfect DIY method of storing dry foods. Buckets, Mylar, and Oxygen absorbers.
The food-grade bucket is armor for Mylar bags and limits the possibility that Mylar will be damaged.
Buckets are stackable and easy to store and organize.
Re-use food-grade buckets for fetching water, fermentation, pickling, and other food-related uses.
Let’s take a look at how long common foods will last when stored in the trifecta.
How Much Food Fits In a Bucket?
Below is a list of foods commonly stored in buckets to maximize shelf-life. You will notice that almost all of them are dry staples. Use the list to plan how many buckets, lids, oxygen absorbers, and Mylar bags you need to maximize the shelf-life of your food stockpile.
The amount of food you can store in a bucket will vary because the size of the food and air volume varies. I suggest having 1-gallon Mylar bags and extra oxygen absorbers on hand to repackage extra food that won’t fit in your food pails.

The chart below will help you choose what size bags and oxygen absorbers you need to store food in buckets.
For example, I typically store wheat and rice in a bucket lined with an 18 “x28” Mylar bag, with a 2000cc oxygen absorber placed inside the bag. The bag is then sealed, and I put an inexpensive lid on top of the bucket.

|Oxygen Absorber Size(s)|

Bucket Type For Food Storage (food or non food grade)
When storing food long-term, you want to use food-grade buckets if the food contacts the bucket.
The bucket should be clean with no prior use to hold chemicals or non-food-grade materials.
Store food in a non-food grade bucket and a sealed Mylar bag should be used.
Unless you are getting free buckets, I don’t see a reason to use non-food grade buckets, they aren’t any cheaper, and they aren’t as helpful in a survival setting.
Food-grade buckets can be re-used for food-grade purposes like moving water, fermenting, or pickling.
