Not all eggs are created equal — especially when it comes to freshness and shelf life. Whether you’re buying from the grocery store or picking up a dozen at your local farm stand, it’s worth knowing how long those eggs are actually good to eat — and why there’s such a big difference.
The store-bought story
In the U.S., federal regulations require that all commercially sold eggs be washed and sanitized before reaching grocery shelves. This process removes the egg’s natural protective coating, called the bloom or cuticle. Without this coating, eggs are more porous and must be refrigerated to slow down spoilage and prevent bacteria from getting inside.
By the time you buy a carton of grocery store eggs, they’ve likely already been through a series of steps: sorting, grading, packing, shipping, and warehousing. Often, they are 4–6 weeks old before you even bring them home — even if the carton still shows a “sell by” or “best by” date in the future.
That’s not necessarily a problem — properly refrigerated store eggs are still perfectly safe to eat for several weeks — but it’s something many consumers don’t realize.
The farm fresh difference
Farm fresh eggs — especially if purchased unwashed — tell a different story.
When hens lay eggs, each egg is naturally coated with a thin protective layer (the bloom). If you leave this coating intact and store the eggs in a cool, dry spot (out of sunlight), they will stay fresh for 2 to 3 weeks at room temperature — no refrigeration required.
If you refrigerate those unwashed eggs later on, they’ll last even longer — up to 3 months or more.
In other words: a farm egg on your counter might be just a day or two old, and still has most of its natural protection intact. That’s a far cry from a month-old store egg in the back of your fridge.
How long do eggs really last?
Here’s a quick comparison:
| Egg Type | Room Temperature | Refrigerated |
|---|---|---|
| Store-bought (washed) | Nope! | ~4–5 weeks after packing date |
| Farm fresh (unwashed) | ~2–3 weeks | ~3 months or more |

The float test
Want to know if an egg is still fresh? There’s a simple method: the float test.
Place the egg in a bowl of water:
- Sinks and lays flat: nice and fresh.
- Sinks but tips upward: still usable but older.
- Floats: no good — compost that one.
Best practices for farm eggs
- Don’t wash until ready to use: Washing removes the protective bloom and shortens shelf life.
- Store cool and dry: Counter is fine for 2–3 weeks. Refrigeration extends life.
- Keep out of sunlight and heat: Warm temperatures accelerate spoilage.
- Use the float test if unsure — it’s quick and reliable.
The takeaway
When you buy farm fresh eggs, you know exactly where they came from — and just how fresh they really are. If left unwashed, they’ll keep longer than most people realize. Store-bought eggs are safe and convenient, but often much older by the time you crack them open.
Either way, now you’ve got the facts — and the float test — to help you make the most of your eggs, whether farm or store.
