How to Tell If Ricotta Is Spoiled
How to identify fresh vs. spoiled ricotta
Ricotta lasts about 1–2 weeks in the refrigerator; discard it immediately if you notice a sour smell, mold growth, or a slimy texture.
Because ricotta is a soft, high-moisture cheese, it is more perishable than harder varieties like Parmesan. When kept properly sealed in the refrigerator, ricotta typically remains safe to eat for 1–2 weeks. However, once the container is opened and exposed to air, its shelf life begins to decline rapidly. To determine if your ricotta is still good, you must evaluate three key indicators: smell, color, and texture. A fresh cheese should have a clean, milky scent and a bright white appearance. If you encounter pinkish tints, fuzzy mold, or a sharp, yeasty odor, the cheese has spoiled. Because moisture allows bacteria to spread quickly through soft cheeses, it is safer to discard the entire container rather than attempting to salvage parts of it.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.

Common questions
How long does ricotta stay fresh in the refrigerator?
Ricotta generally lasts 1–2 weeks when stored in an airtight container in the refrigerator. Quality and safety decrease more quickly once the seal is broken.
What are the signs of spoiled ricotta?
Look for pink, gray, or fuzzy mold, a slimy surface texture, or a sour, yeasty, or pungent odor. If any of these are present, discard the cheese.
Is it safe to eat ricotta with liquid on top?
Yes, if the liquid is clear whey and the cheese smells fresh and looks white. However, if the liquid is cloudy or accompanied by a sour smell, toss it.
Can I scrape mold off soft cheeses like ricotta?
No. Because ricotta is soft and moist, mold roots can penetrate deep into the cheese where you cannot see them. Discard the entire container if mold appears.
Does freezing affect ricotta texture?
Freezing ricotta can cause it to become grainy or crumbly once thawed. It is best used in cooked recipes like lasagna rather than for fresh spreads after freezing.
Ricotta is a high-moisture cheese that moves quickly from fresh to spoiled. Trust your nose: if the scent is anything other than clean and milky, toss it.
