What not to eat when pregnant
To reduce the risk of getting a foodborne illness during pregnancy and eating foods that may harm your baby, there are certain things that you will need to give up or take care with when you’re pregnant.
Food safety is also really important when you are pregnant – for more information see Food safety in pregnancy.
What should I avoid when pregnant?
Meat and fish
- Pâté (all types), as on rare occasions can contain listeria bacteria, which can be harmful to you and your baby.
- Raw or undercooked meat, including cured uncooked meats for example parma ham (prosciutto) and salami. These can carry bacteria that cause foodborne illnesses and parasites which on rare occasions can cause an infection called toxoplasmosis. Meat should be cooked thoroughly with no pink meat or blood left (rare meat).
- Liver contains very high levels of vitamin A, which can harm your baby.
- Shark, marlin and swordfish, as they can contain high levels of mercury that can harm your baby’s developing nervous system. Tuna can also contain mercury, so you should not eat more than two tuna steaks or four cans a week.
- Raw shellfish, as it carries a risk of food poisoning. Thoroughly cooked shellfish is safe to eat.
- Raw or lightly cooked wild fish, in dishes such as sushi, unless the fish has been frozen first. Wild fish can sometimes contain parasitic worms but freezing or cooking kills any worms. Sushi containing farmed fish, such as farmed salmon, is very unlikely to contain parasitic worms.
- Fish is great for your baby’s health and development, but you should not eat more than two portions of oily fish and certain non-oily fish (dogfish, sea bass, sea bream, turbot, halibut, crab) a week because they can contain pollutants, which may harm your baby.
Cheese and dairy
- Soft blue cheeses (such as gorgonzola and roquefort), soft cheeses with white rinds (mould ripened - such as brie and camembert) and soft cheeses made from unpasteurised milk, unless thoroughly cooked to kill any bacteria in the cheese. All hard cheeses are safe to eat, even if unpasteurised or with blue veins (such as stilton), because they contain less water and so bacteria is less likely to grow.
- Unpasteurised (raw) milk and foods containing it, unless thoroughly cooked, as they can contain bacteria that are harmful to you and your baby.
- Raw or partially cooked eggs, as well as products containing raw eggs such as homemade mayonnaise, salad dressings and some ice creams. Raw eggs might contain salmonella which can cause food poisoning. Most shop-bought mayonnaises, dressings and ice creams contain pasteurised eggs so are safe to eat, but check if you are eating out at a restaurant as they may make their own.
