First Trimester Foods to Avoid: Complete Guide
Knowing what to avoid can feel overwhelming in early pregnancy, especially when advice seems to come from every direction. The good news is that the UK list of foods to avoid is fairly short and specific — most of it comes down to reducing your risk of a small number of infections, such as listeria, salmonella, and toxoplasmosis, which can be more serious during pregnancy.
Foods to avoid completely
These foods carry a risk of infection or contain substances that can affect your baby's development, so it's best to avoid them for the whole of your pregnancy, not just the first trimester:
- Soft mould-ripened cheeses such as brie, camembert, and chèvre (soft goat's cheese), unless they're thoroughly cooked
- Soft blue cheeses such as gorgonzola or roquefort, unless cooked until steaming hot throughout
- Unpasteurised milk and dairy products, including some artisan cheeses — check the label if you're unsure
- Pâté of any kind, including vegetable pâté, due to the risk of listeria
- Raw or undercooked meat, including rare steak and pink poultry
- Liver and liver products, because of very high vitamin A levels which can be harmful in pregnancy
- Raw or undercooked eggs, unless they carry the British Lion stamp, which indicates they're produced to a higher salmonella-safety standard
- Raw fish and shellfish, such as sushi made with raw fish, oysters, and unpasteurised smoked fish
- High-mercury fish, including shark, swordfish, and marlin, which can affect the developing nervous system
- Unwashed fruit, vegetables, and salad, plus raw bean sprouts and raw sprouted seeds, due to potential bacterial contamination
- Alcohol, since no amount is known to be completely safe during pregnancy
Foods to limit rather than avoid
A few foods aren't banned outright but are safest in moderation:
- Caffeine, which should be limited to around 200mg a day (roughly two mugs of instant coffee)
- Oily fish such as salmon and mackerel, limited to two portions a week due to mercury and pollutant levels
- Tuna, limited to around two fresh tuna steaks or four medium cans a week
Foods that are safe to enjoy
It's worth remembering how much is still perfectly fine, so pregnancy doesn't feel like a constant list of "no":
- Pasteurised hard cheeses like cheddar, parmesan, and mozzarella
- Thoroughly cooked meat, poultry, and eggs
- British Lion stamped eggs, even served runny
- Cooked fish and shellfish, prepared hot and fresh
- Well-washed fruit, vegetables, and salad
Frequently Asked Questions
What foods should I avoid in early pregnancy?
Avoid soft mould-ripened and blue cheeses (unless cooked), unpasteurised dairy, pâté, raw or undercooked meat and eggs, liver, raw fish and shellfish, high-mercury fish, unwashed salad, raw bean sprouts, and alcohol. Limit caffeine to around 200mg a day and oily fish to two portions a week.
Can I eat cheese in early pregnancy?
Pasteurised hard cheeses like cheddar and parmesan are safe throughout pregnancy. Soft mould-ripened cheeses (brie, camembert) and soft blue cheeses are only safe if cooked until steaming hot all the way through, since raw versions carry a small listeria risk.
What if I ate something on the "avoid" list before I knew I was pregnant?
Try not to worry — many women accidentally eat something from the list before realising they're pregnant, and the actual risk from a single exposure is generally low. If you're concerned, or develop symptoms like a high temperature, flu-like illness, or unusual vaginal discharge afterwards, contact your GP or midwife for reassurance.
