Common questions

How long does cottage cheese (opened) last in the fridge?

1 week once opened, and 2 weeks while sealed and unopened, in a fridge running at 0–5°C. Count from the day you open it, and use the printed date if it is earlier.

How can I tell if cottage cheese (opened) has gone off?

On hard cheese, a small patch of mould can be cut away with at least 2.5 cm (1 inch) of margin; on soft, crumbled, grated or sliced cheese, any mould means bin it. Do not rely on this alone: the time guideline matters even when everything looks fine.

Can I freeze cottage cheese (opened) to keep it longer?

Freezing is not recommended for this food; the texture tends to suffer badly. Buy or cook only what you will use in time.

Does my fridge temperature really matter?

Yes. These times assume a fridge at 0–5°C, which is what the Food Standards Agency says to set it to. Bacteria grow faster in a warmer fridge, and many fridges run warmer than their dial suggests, so a cheap fridge thermometer is worth having.
