What does rotation mean?
Rotation means using older food first and replacing it with new. The common phrase is first in, first out. When you buy or preserve something new, it goes to the back, and the older items move to the front.
Without rotation, the oldest food ends up at the back of the shelf and is forgotten until it is no longer good.
A rotation habit costs almost nothing, but it protects the money you spent on food and the work you put into growing and preserving it.
How do you date what you store?
Write the date on everything you pack, preserve or open, using a marker on the lid, the bag or a piece of tape. For store-bought items, note the date you bought them if the package date is hard to read. Keep the system simple enough that you will really use it.
For home-preserved foods, record the date and the recipe source as well. If a recipe source later turns out to have been outdated or unsafe, you will know which jars to check. A weekly glance at the front of each shelf takes less than a minute and keeps older items from hiding at the back.
- Date every package, jar and bag
- Place new items behind old ones
- Record the recipe source on home-preserved jars
- Keep one marker where you store food
How do you build a system?
Shelves that allow loading from the back, or rotating can racks, make rotation easier. If you do not have these, a simple rule works: always load from the left and take from the right, or similar. Keep like items together so that you can see what is oldest.
Keep an inventory list, on paper or on a phone, with item names and counts. Update it when you add or remove things. Looking at it before shopping stops you from buying what you already have.
If a shelf layout makes rotation hard, change the layout rather than blaming yourself. A system that fits the space is the one that gets used.
How do you build rotation into meals?
Plan meals around what is due to be used. Once a month, scan the pantry and freezer for items that are close to their best quality and build a few meals around them. Soups, casseroles and baked dishes handle odds and ends well.
If you have more than you can use, give some to neighbors, a food pantry or family before it expires. Set a reminder on your calendar for the first of each month to do a quick review of the pantry and freezer, and treat it like any other chore.
How long does stored food last?
It depends on the food, the packaging and the storage conditions. Package dates are often about quality, not safety, and home-preserved foods have their own guidance. Ask your extension office or look at the National Center for Home Food Preservation for current recommendations on how long each type keeps.
Do not rely on rules of thumb you cannot verify. Heat, humidity and light all shorten shelf life.
Quality and safety are different questions. Food that has lost some quality may still be safe, but food that has been stored wrongly may be unsafe even if it looks fine.
When should you discard food?
Throw out food with off smells, mold, bulging or leaking containers, broken seals, pest damage or signs of moisture in dry goods. Do not taste food to find out if it is safe. With home-canned goods, discard any jar with a loose lid, leaking, bulging or spurting contents.
When in doubt, throw it out, and dispose of it where people and animals cannot reach it.
How do you handle the freezer?
Freezers need rotation too. Keep a list on the door or lid with the contents and dates, and cross items off as you use them. A freezer that is only filled and never inventoried turns into a place where food is lost.
Group items in bins by type, such as meat, vegetables, prepared meals and baked goods. Put new items at the back or bottom, and keep the oldest at the front or top.
Check your freezer temperature with a thermometer, and ask your extension office what to do after a power outage. Start small. Pick one shelf or one freezer drawer, put it in order and keep it that way for a month. Once the habit holds, extend it to the next area. Rotation that is built in slowly lasts, and a system you can keep up beats an elaborate one you abandon.
Key takeaways
- Use older food first and put new food at the back.
- Date everything and note the recipe source for home-preserved items.
- Keep a simple inventory and review it before shopping.
- Discard food with any sign of spoilage; never taste to test.
