What that means
This keeps longer, but cold storage and clean handling still matter.
Use this as a planning window, then check the real-world spoilage signs below before eating.
Make Oregano last the full window
Do
- Refrigerate promptly after each use, at 5°C / 40°F or below.
- Use a clean utensil every time you take a portion.
- Keep it sealed — the original lid or an airtight container.
- Skip the freezer for this one — Freeze damage will appear.
Don't
- Leave it out on the counter while cooking or serving.
- Double-dip or return unused portions to the container.
- Store it in the fridge door if you open the fridge often — it is the warmest spot.
- Taste it to "test" safety. If in doubt, throw it out.
How Oregano compares with other fruit and vegetables
Opened storage windows vary a lot within a category. Days shown are after opening, refrigerated.
Where this guidance comes from
The Oregano window blends official US food-safety guidance with typical manufacturer opened-storage instructions. The label on your specific product always wins if it is stricter.
Storage note
US mode uses the conservative end of the USDA FoodKeeper record (14–21 days, refrigerated). UK mode applies FSA chilling and label-first rules to the same record. The product label always wins when it gives a shorter period.
