Common questions
How can I tell if tzatziki has gone off?
Trust obvious signs — sour or 'off' smells, slime, mould, colour changes — but don't rely on them: the bacteria that cause food poisoning (listeria especially) grow without changing how food looks or smells. That's why the time guideline matters even when everything seems fine.
Can I still eat tzatziki after 2 weeks?
The guideline is where quality and safety are both still on your side. Past it, risk climbs — and because dangerous bacteria are invisible, 'it seems fine' isn't a reliable test. The boring-but-true answer: when in doubt, throw it out.
Can I freeze tzatziki to keep it longer?
Freezing isn't recommended for this food — the texture tends to suffer badly. Better to buy or cook only what you'll use in time.
Does my fridge temperature really matter?
Enormously. These times assume 0–5°C. Every degree warmer speeds bacterial growth — a fridge running at 8–10°C can halve the safe life of chilled food. A £5 fridge thermometer is the cheapest insurance you can buy.
