Hummus
Opened hummus lasts 4–6 days in the fridge and about 4 months in the freezer.
How long it keeps — Opened
Fridge times here are mostly quality windows from USDA FoodKeeper and related federal guidance — past them, flavor and texture decline; discard when mold, slime, off odors, or other spoilage signs appear. Freezer times are also quality windows at 0°F (FoodKeeper / FDA where cited). Not medical advice.
How to store hummus
Opened hummus keeps about 4–7 days refrigerated, and unopened refrigerated tubs should be used by their date.
Keep it in a sealed container in the body of the fridge rather than the door. Smooth the surface flat and pour a thin layer of olive oil over it — this excludes air, slows drying, and genuinely extends its life by a day or two.
Always serve with a clean spoon into a separate bowl. Dipping vegetables or pita straight into the tub introduces starch, moisture, and bacteria, and is the fastest way to cut the window short.
Do not leave hummus out for more than two hours.
Hummus freezes reasonably well for about 4 months. Thaw in the refrigerator and stir hard, with a splash of olive oil or water, since it separates.
By state & packaging
Why hummus goes bad
Hummus looks like a preserved condiment and behaves like a fresh food, which is where people go wrong with it.
Its base is cooked chickpeas — a legume that is high in protein and moisture and close to neutral in pH. The tahini adds fat and the lemon juice adds some acid, but not nearly enough to bring the overall mixture below the pH 4.6 safety threshold. Garlic contributes some antimicrobial activity but not preservation. The result is a moist, protein-rich, low-acid food, which is exactly the profile that requires refrigeration and a short window.
Commercial hummus is often high-pressure processed or contains preservatives such as potassium sorbate, which is why an unopened tub outlasts a homemade batch considerably. Opening it ends that advantage.
Hummus has been subject to Listeria recalls in the US, which fits: it is a ready-to-eat refrigerated food, and Listeria grows at refrigerator temperature.
The most reliable spoilage signal is fizzing or bubbling, which means wild yeast is fermenting the chickpea sugars, and it is often accompanied by a slightly domed lid. A sour or alcoholic smell, any mold, and a watery separated layer with an off odor all mean discard.
A little liquid on the surface of fresh hummus, with no off smell, is normal separation.
Signs it has gone bad
Any of these means discard it. Do not taste food to check (FDA / CDC). Fridge times above are mostly quality guidance — use these spoilage signs (and package condition) to decide when to toss, rather than treating the day count as a raw-meat-style safety cliff.
What the date on the package means
Jar and bottle dates on shelf-stable condiments are usually "best by" quality dates, not federal safety deadlines — see USDA FSIS food product dating. Unopened product kept cool and dry is typically fine through that date for quality.
After opening, follow the refrigerator (or pantry) window on this page and the label. Discard if mold, off odors, or unusual separation appear — do not scrape mold and keep using it.
FAQ
Can hummus sit out at a party?
Two hours maximum, one hour outdoors above 90°F. Put out small bowls and refill from the fridge.
Is hummus still good after a week opened?
Opened hummus is typically 4–6 days refrigerated. Past that, discard it.
Does the tub date matter after opening?
Use the shorter of the printed date and the 4–6 day opened fridge window. Discard if it sat out more than 2 hours.
