Foods to avoid in pregnancy: a practical UK safety guide
Make safer food choices without fear, using the NHS approach to food hygiene, alcohol and higher-risk foods.
7 min read · Sources reviewed 21 June 2026
Most everyday foods are compatible with pregnancy. The aim is not perfection: it is lowering avoidable infection and contaminant risks while keeping meals varied, nourishing and manageable.
The highest-value changes
In the UK, NHS guidance advises avoiding alcohol in pregnancy because there is no known safe amount. It also highlights foods that can carry a higher risk of listeria, toxoplasmosis or other food-borne illness, plus foods high in vitamin A.
Food guidance changes between countries, especially for eggs, cheese and fish. This article follows UK NHS guidance; use your local public-health advice if you live elsewhere.
- Avoid liver and liver products, which can contain high levels of vitamin A.
- Avoid unpasteurised milk and mould-ripened soft cheeses unless they are thoroughly cooked until steaming hot.
- Avoid raw or undercooked meat and raw shellfish; wash fruit, vegetables and salad carefully.
- Avoid shark, swordfish and marlin; follow current guidance on oily fish and tuna limits.
Make food hygiene the default
Separate raw meat from ready-to-eat food, wash hands and utensils, cook food thoroughly and refrigerate leftovers promptly. These small habits prevent more problems than a long list of restrictive rules.
Check labels for pasteurisation and cooking instructions. If you are unsure about a restaurant dish, ask whether it contains raw egg, raw shellfish, unpasteurised dairy or undercooked meat.
- Reheat leftovers until piping hot and avoid food that has been left at room temperature for long periods.
- Use a clean chopping board for ready-to-eat foods after preparing raw meat.
- Discuss supplements with your midwife or pharmacist; do not take vitamin A supplements in pregnancy.
Build meals around what you can manage
Nausea, food aversions and fatigue can make idealised meal plans unrealistic. Small, regular meals and easy sources of protein, fibre and fluids can be a kinder starting point. If you cannot keep fluids down, are losing weight, or have persistent vomiting, contact your maternity team.
A prenatal supplement may be recommended, but it does not replace food. Your clinician can advise on folic acid, vitamin D, iron or other needs based on your diet and health.
When to get help
Contact a healthcare professional urgently if you cannot keep fluids down, have signs of dehydration, or are worried about severe vomiting. Ask your midwife or pharmacist before starting supplements or herbal products.
FAQ
Can I eat eggs in pregnancy?
Guidance depends on the country and production standard. In the UK, hen eggs with the British Lion mark can be eaten runny; check current local guidance elsewhere.
Do I need to eat perfectly?
No. Aim for safer handling and a varied pattern over time. Ask for individual support if nausea, allergies, diabetes or dietary restrictions make eating difficult.
