Common questions
How long does cucumber last in the fridge?
4–6 days 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 cucumber has gone off?
Sliminess, mushy patches, mould and a sour or fermented smell are the usual signs; cut away a small bruise but discard anything mouldy or slimy. Do not rely on this alone: the time guideline matters even when everything looks fine.
Can I freeze cucumber 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.
