Common questions
How long does tzatziki last in the fridge?
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 tzatziki has gone off?
Smell and appearance are unreliable here: the bacteria that matter in cooked dishes (including Bacillus cereus in rice and pasta) often do not change how food smells or looks. Mould, sliminess or a sour smell are obvious reasons to bin it, but a dish can be unsafe without them.
Can I freeze tzatziki 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.
