Common questions
How long does yoghurt (opened) last in the fridge?
1–2 weeks in a fridge running at 0–5°C (USDA FoodKeeper guidance). After that, quality and safety both start to slip, and because the bacteria that cause food poisoning are invisible, ‘it seems fine’ is not a reliable test. When in doubt, throw it out.
How can I tell if yoghurt (opened) has gone off?
A sour smell, lumps or curdling, a changed taste or any mould (other than on hard cheese) mean it should go. Do not rely on this alone: the time guideline matters even when everything looks fine.
Can I freeze yoghurt (opened) to keep it longer?
Yes. For best quality, freeze it for around 1–2 months; it stays safe beyond that because freezing halts bacterial growth, and only texture and flavour decline.
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.
