Spoiled cheese may cause gastrointestinal symptoms including nausea, vomiting, and diarrhea. It is important to discard mozzarella that shows signs of spoilage to avoid health risks.
Common Questions About Mozzarella Cheese Safety
Is mozzarella cheese still safe after being left out overnight?
Mozzarella Cheese left out overnight (more than 2 hours at room temperature) should be discarded. Bacteria multiply rapidly between 40°F and 140°F. Even if it looks and smells fine, harmful bacteria like Salmonella or E. coli may be present at unsafe levels. Do not taste-test to determine safety.
Can you eat mozzarella cheese that smells fine but is past its expiration date?
With mozzarella cheese, do not rely on smell alone. Pathogenic bacteria that cause foodborne illness are often undetectable by smell, taste, or appearance. If mozzarella cheese is past its use-by date, discard it regardless of how it smells. "Best by" dates on lower-risk items indicate quality, not safety — but mozzarella cheese falls into a higher-risk category.
Is freezer-burned mozzarella cheese safe to eat?
Freezer burn on mozzarella cheese is caused by air reaching the food's surface and causes dry, discolored patches. Freezer-burned mozzarella cheese is safe to eat — it is a quality issue, not a safety issue. The affected areas may have an off flavor or dry texture. You can trim away freezer-burned portions before cooking. To prevent freezer burn, use airtight packaging and remove as much air as possible before freezing.
What does it mean if mozzarella cheese has changed color or texture?
Color or texture changes in mozzarella cheese can indicate bacterial growth or chemical breakdown. Gray, green, or slimy surfaces are strong indicators of spoilage. A sticky or tacky feel, unusual film, or off-color liquid are all reasons to discard immediately. Some color change is natural (e.g., slight darkening of red meat due to oxidation), but when combined with an off smell or slimy texture, it signals the product is unsafe.
