CanYouEat helps UK readers make clearer food-safety decisions when they are unsure whether something is safe to eat.
It is built for everyday “can I eat this?” situations: food past a date label, leftovers in the fridge, meals left out, pregnancy food questions, reheating doubts, chilled food storage, and worries after already eating something.
Start with the situation closest to yours. If someone is unwell, pregnant, very young, older, immunocompromised, or symptoms are severe, use NHS advice and seek medical help where needed.
What do you need help with?
Food past its date label
Best for: use-by dates, best-before dates, opened packets, chilled food, cupboard food, meat, fish, dairy and ready meals.
A use-by date is about safety. A best-before date is about quality. That difference matters because food can look or smell normal and still be unsafe, especially if a use-by date has passed or storage instructions were not followed.
Check the date-label guide: use-by vs best-before guidance
Pregnancy food questions
Best for: cheese, eggs, fish, meat, pâté, chilled ready-to-eat food, leftovers, takeaways and foods that may carry a higher risk during pregnancy.
Pregnancy food advice is more cautious than general adult food advice. Some foods need to be avoided, cooked until steaming hot, or checked against NHS pregnancy guidance.
Use the pregnancy guide: pregnancy food safety guidance
Leftovers, reheating and food left out
Best for: cooked food in the fridge, takeaway leftovers, rice, pasta, chicken, food left on the counter, meals cooled late and food you want to reheat.
Leftover safety depends on what happened after cooking: how quickly the food cooled, whether it was chilled, how long it was stored, and whether it can be reheated until steaming hot.
Follow the leftovers guide: leftovers guidance
Already ate something risky
Best for: food you already ate that may have been out of date, undercooked, spoiled, left out too long, poorly stored or unsafe during pregnancy.
Stop eating the food, avoid tasting more to check it, keep the packaging if useful, and watch for symptoms. Get medical advice sooner if symptoms are severe or the person affected is higher risk.

Fridge and chilled food safety
Best for: fridge temperature, chilled food storage, food left out of the fridge, opened chilled food, and whether a use-by date still applies after poor storage.
Chilled food safety depends on temperature, packaging instructions and how long the food has been out of the fridge.

How CanYouEat works
CanYouEat is a UK food-safety decision-support site. It helps turn common food questions into clearer next steps.
The aim is to help you decide whether to:
- eat the food
- avoid it
- throw it away
- store it correctly
- reheat it until steaming hot
- check pregnancy-specific guidance
- watch for symptoms
- seek medical advice
CanYouEat does not replace the Food Standards Agency, NHS, a GP, pharmacist, midwife, NHS 111 or emergency services. It helps you find the right type of guidance faster.
Why not just search?
Food-safety search results can mix official guidance, forum replies, old blog posts, food waste tips and personal opinions. That is not ideal when you need a practical safety decision.
CanYouEat separates questions that are often confused:
- use-by dates and best-before dates
- food safety and food quality
- leftovers stored safely and food left out too long
- general adult advice and pregnancy advice
- deciding whether to eat something and what to do after already eating it
That separation matters. A tin past its best-before date is not the same as chilled chicken past its use-by date. Food kept cold is not the same as food left out overnight. A pregnancy food question may need a more cautious answer than the same question for a healthy adult.
Our source approach
CanYouEat is UK-focused.
We use the Food Standards Agency for food-safety basics such as date labels, chilling, freezing, defrosting, reheating and food hygiene.
We use the NHS for pregnancy guidance, food poisoning symptoms, vulnerable groups and when to seek medical help.
We do not advise tasting suspicious food to check whether it is safe. We do not say food is safe just because it looks or smells fine. Where there is uncertainty, higher risk, pregnancy, symptoms or poor storage, our guidance is cautious.

FAQs
Is CanYouEat medical advice?
No. CanYouEat gives practical UK food-safety guidance, but it does not diagnose illness or replace NHS, GP, pharmacist, midwife, NHS 111 or emergency advice.
How should I use CanYouEat?
Choose the situation closest to your question: date labels, pregnancy, leftovers, food left out, fridge storage or already eating something risky. Then follow the specific guide for that situation.
Can I tell if food is safe by smelling it?
Not reliably. Food can look or smell normal and still be unsafe, especially if a use-by date has passed or storage has been poor. Do not taste suspicious food to check whether it is safe.
Why does CanYouEat separate use-by and best-before dates?
Because they mean different things. Use-by dates are about safety. Best-before dates are about quality. Treating them as the same can lead to unsafe decisions or unnecessary food waste.
What if I cannot find my exact food?
Start with the closest situation rather than the exact food name. For example, a question about cooked chicken left out overnight belongs with leftovers and food left out. A question about yoghurt past its date belongs with date labels and chilled food storage.
What should I do if I already ate something risky?
Stop eating it, keep the packaging if useful, and watch for symptoms. Seek medical advice if symptoms are severe, persistent, or if the person affected is pregnant, a baby, older or immunocompromised.
Start with the safest next step
Food safety depends on the exact situation: the food, the date label, storage, temperature, pregnancy status and whether anyone has symptoms.
Start with the route closest to yours. CanYouEat helps you move from uncertainty to a clearer, safer next step.
