Eating some foods and drinks during pregnancy may increase the risk of harm to you and your baby.
Raw or undercooked meat
Avoid undercooked meat, especially sausages or minced meat. Be careful to cook them thoroughly so there’s no trace of pink or blood. Although the risk is low, you may also prefer to avoid raw cured meat, such as Parma ham, chorizo, pepperoni and salami. It’s safest to eat well-cooked meat when you’re pregnant.
Why? There is a risk of toxoplasmosis, a tiny parasite that lives in raw meat, soil and cat poo and can harm the baby.
Unpasteurised milk and dairy products
All milk sold in shops, supermarkets and restaurants in the UK is pasteurised and fine to drink. If you are a farmer or use farmers’ markets, however, you might come across unpasteurised milk and products made from it. You should avoid these. This also applies to goat's milk and sheep's milk. If you only have access to unpasteurised milk, boil it before using.
Why? There is an increased risk of toxoplasmosis, listeriosis and Campylobacter.
Liver and other foods containing vitamin A
Avoid liver and liver products, such as liver pâté and liver sausage. It's not safe to take multivitamins containing vitamin A or fish liver oils, such as cod liver oil. Also steer clear of any foods that have vitamin A added (they may say 'fortified with vitamin A').
Why? Liver has high levels of vitamin A, and too much of this can harm your baby.
Avoid all types of pâté, including vegetable pâté.
Why? They may contain listeria. These are bacteria that can cause an infection called listeriosis. Listeriosis can harm a baby during pregnancy or cause severe illness in a newborn. Liver pate can also have high levels of vitamin A, which is harmful to the baby.
- mould-ripened soft cheeses, such as brie, camembert and others with a similar rind, including goats' cheese
- soft blue-veined cheeses, such as Danish blue, gorgonzola and Roquefort.
Why? There’s a risk that these cheeses could contain listeria.
Undercooked ready meals
It’s important to follow the cooking instructions on the pack of any ready meals you eat. Also, check that the meal is piping hot all the way through before you eat it. This is especially important for meals containing poultry, such as chicken or turkey.
Why? There’s a risk that these could contain listeria.
Raw eggs* or undercooked eggs
It’s important that any eggs you eat are cooked until the yolks and whites are solid all the way through. Using eggs in cooked recipes is safe but avoid foods that have raw egg in them, such as homemade mayonnaise or mousse.
Why? There’s a risk of salmonella, a common cause of food poisoning that can harm the baby and make you very unwell.
*Recent research suggests that there is “very low” risk of salmonella from UK eggs produced under the Red Lion code and that they are safe to eat in pregnancy. The Food Standards Agency (FSA) is currently reviewing its advice to pregnant women. Find out more.
Certain kinds of fish
Fish is good for you and you should aim to eat at least two portions a week, including one portion of oily fish, such as fresh tuna, mackerel or sardines. However, there are some types of fish you should avoid and some you should limit:
- Avoid shark, swordfish and marlin as they have high levels of mercury, which could affect your baby’s nervous system.
- Limit tuna to no more than two fresh steaks or four medium cans of tinned tuna a week because it also has high levels of mercury.
- Limit oily fish (salmon, mackerel, sardines, trout, herring, pilchards) to no more than two portions a week as they contain pollutants.
- Avoid eating raw shellfish, such as oysters, as they may give you food poisoning. (Cooked shellfish are fine – these include cold pre-cooked prawns.)
Try to avoid eating from your toddler’s plate or with their knife and fork. It can put you at risk of a viral infection called Cytomegalovirus (CMV), which is often contracted by young children at nurseries. The virus is harmless to children but could have harmful effects on an unborn baby.
It's safest to avoid alcohol completely during pregnancy, especially in the first three months. If you do choose to drink after that, keep it to a maximum of one or two units, no more than once or twice a week.
Why? Alcohol can harm you and your baby, and experts cannot be sure that any amount of alcohol is safe.
Drinking a lot of caffeine in pregnancy has been linked to miscarriage and low birth weight.
Caffeine is found in:
- tea and coffee
- cola and other soft drinks
You should limit your caffeine intake to no more than 200mg a day during your pregnancy.
A can of cola has around 40mg of caffeine, a mug of tea has around 75mg, a bar of plain chocolate has around 50mg, a cup of instant coffee has around 100mg, a mug of filter coffee has around 140mg.
It can add up quickly - you will reach your limit with, for example:
- one bar of plain chocolate and one mug of filter coffee
- two mugs of tea and one can of cola
Can I eat peanuts during my pregnancy?
Doctors used to say you shouldn’t eat peanuts or peanut butter if you or your baby’s dad have asthma, eczema or allergies. This was because it was thought that eating peanuts might make the baby more likely to be allergic to them. But the latest research has shown no clear evidence that eating peanuts during pregnancy affects the chances of your baby developing a peanut allergy.
What if I've already eaten something risky?
Don't panic. If it didn't make you ill at the time, it's unlikely to have affected you or your baby. Talk to your doctor or midwife if you're worried about something you've eaten.
A survey of 2,100 women in the UK has shown that 4 out of 5 aren't sure how many calories to eat when pregnant.
The study looked at data of 12,500 women during their pregnancy.
These 7 simple tips will help you have a healthy diet during pregnancy.
Find out why breakfast is important in pregnancy and get some healthy pregnancy breakfast ideas
How much should you eat in pregnancy? During most of your pregnancy you do not need to take in extra calories (over the recommended 2,000 a day for women).
Choosing healthy foods is very important but the amount you eat is important too. Find out what a 'portion' means for different foods
New research from the University of Cambridge could revolutionise care for pregnant women with type 1 diabetes.
New research suggests that having a high fat and high sugar diet in pregnancy may cause behavioural problems in young children.
When it comes to eating out or getting takeaway, remember that foods low in fat and sugar are best for you and your baby.
A recent survey has revealed unhealthy levels of salt and fat in ready-made savoury dips.
Pregnancy multivitamins are a waste of money because most mums-to-be do not need them, according to researchers.
In pregnancy it's important to eat well. If you are used to eating foods that are high in sugar, salt and fat, you can make a few changes that will be good for you and your baby.

By Midwife @Tommys on 17 Jan 2019 - 09:50
Hi - Thank you for your message. Please try not to worry, it sounds as though you were quite unwell and needed to take the antibiotics for a serious infection. If you are worried please discuss with your midwife/Dr who can advise on the safety of the exact medication you took.

I have been eating raw honey from friends' bees nearly every day in pregnancy on the basis I had no info from NHS/midwife that this was dangerous - I know it is not good for feeding young babies. However I have seen a few sites saying raw honey is bad in pregnancy as well - should I be avoiding non shop-bought honey??
Second thing: I have been eating some yogurts from supermarkets in the UK and France without 'pasteurised' on the label because I understood that by EU law they would have to state clearly if they were unpasteurised. Ditto creme fraiche/cream. I've also eaten homemade ice cream in restaurants if there's no egg, without checking about the dairy. Is this wise?

Hi,i went to the clinic on Wednesday and found that I'm pregnant.I had a c/s last year Feb and I lost the baby when he was 5 months old,he was a pre-term baby and now I'm pregnant again,and I'm worried about my scar,i never had any problems with it just that it's going to be stretched now since I'm pregnant. am I in the highest risk? As for my baby's safety,they said my discharge wasn't okay,and I'm worried if my baby can possibly be affected coz I suspected I was pregnant from 2 months ago but the tests were all negative until this week.
By Midwife @Tommys on 3 Dec 2018 - 14:24
Hi, So sorry to hear of the distress you have been through this year. It must have been a roller-coaster for you. I am sorry but I am reluctant to advise you without medical details. I hope that you are being looked after with the best care. Please do talk to your doctors about your concerns or call us at Tommy's to chat on 0800 0147 800

Hi there, a friend of mine made a soft cheese sandwich for me and I had one bite before I suspected it may not be a cheese I could eat! She’s since told me it was actually mould-ripened goat’s cheese and doesn’t know if it was pasteurised (it’s from Tesco but the label doesn't say). I’m 29 weeks and very worried - it was only one bite but concerned re toxoplasmosis and listeria. Should I be worried? Thank you
By Midwife @Tommys on 14 Nov 2018 - 15:28
Hi, We do advise you to avoid these types of cheese but please don't worry, Listeria is actually very rare and you don't need to do anything unless you have symptoms. High temperature over 38 degrees, vomiting, diarrhoea or aches and pains. If you do have these symptoms please see your GP. There is a theoretical risk of Toxoplasmosis but again this is very unlikely. To be completely certain you could request a blood test through your GP.

I've just eaten a chicken and bacon caesar wrap at Costa and turned over the packet to read "pregnant women should not consume unpasteurized milk". I'm freaking out massively. What should I do? I don't understand how they can service something that is dangerous.
By Midwife @Tommys on 9 Nov 2018 - 15:53
Please do not worry, it is likely that the dressing itself is pasteurized to extend the shelf life of the product. Otherwise the risk is very low, if by chance you do start to feel unwell then do see your GP but this is very unlikely.
By Nicola (not verified) on 30 Oct 2018 - 13:52
I am just over 5 weeks pregnant and eat some blackcurrant sweets that had liquorice extract in them. I have read that liquorice should be avoided in pregnancy and now I am worried. I don't normally eat it and only had some yesterday then today. Should it be ok?
By Midwife @Tommys on 2 Nov 2018 - 10:55
Please try not to worry, the amount of liquorice in the sweets you have described will be very low. The evidence is quite inconclusive when it comes to the effect of liquorice in pregnancy, therefore the guidance is to avoid high or concentrate levels of liquorice such liquorice root as a herbal remedy, but having a moderate amount eg sweets or tea is thought to be fine.

I work as a nurse and my shifts are 12hrs @ i also have 1hr each way traveling time. I started to feel sick at just 5 weeks and have not manged to go to work since and i am now 7 weeks. Im worried im the only one out there is this somthing i need to just push on through??. I had this with my daughter 10 years ago and was sick all the way through. Im worried people dont understand and think im lieing but i feel so sick i cant cope going to work. Will it get better ?? Am i the only one who cant face work atm?
By Midwife @Tommys on 26 Oct 2018 - 10:10
Sorry to hear that you are feeling so sick and nauseous at the moment. Every pregnancy is different for everyone, but if you do not feel fit to work then you do need to look after yourself and take time off if you feel that you need it. Pregnancy related sick leave does not count towards your sickness level. Otherwise, if you feel comfortable in doing so, it maybe worth having a talk with your manager about any flexible arrangements that can be made for you whilst you are feeling this way.
For many, sickness and nausea does improve by the second trimester, however for some, unfortunately they do suffer all the way through the pregnancy. Do be in touch with your GP and midwife (when you have one) for support also.

Hi, I ate pesto the other day and looked at the ingredients after to see it contains pecorino cheese. I understand it’s a hard cheese so safe even if unpasteurised, but wasn't sure as it’s made of ewe’s milk. If it’s unpasteurised have I risked toxoplasmosis and listeria? Very anxious.
By Midwife @Tommys on 23 Oct 2018 - 09:15
Please don't worry. Pesto sauce is quite safe to eat in pregnancy and a good source of calcium, iron and other essential vitamins. Hard cheeses are not on the list of foods to avoid in pregnancy as they contain less water and are less likely to harbour bacteria than soft cheeses. Enjoy your pesto!

I just found out that I am pregnant. Before knowing that I'm pregnant I had a large portion of chicken liver once off. I'm concerned about the effects this may have had. I can't seem to find online what portion of liver is safe. I'm really concerned. Please help!?
By Midwife @Tommys on 23 Oct 2018 - 09:21
Please don't worry. Chicken liver pate contains Vitamin A which we need in our diet for our vision, our skin and our immune system. We do however know that too much is not recommended so we advise to eat foods high in vitamin A only once a week.

Hi, I’ve continued to eat Rowse honey throughout my pregnancy - now 24 weeks - but looked online and it says that the honey is not pasteurised. I can’t find information anywhere. Is it safe or should I stop? Thanks
By Midwife @Tommys on 11 Oct 2018 - 13:59
Hi Emma, Thank you for your comment.
Honey is fine to eat in pregnancy but it is not suitable for babies under the age of one years old due to the gut being immature. On the Rouse website they say that their honey is unpasteurised but that it is still fine to eat in pregnancy. If you are still concerned then just stop eating it but you should be fine to continue. Hope this helps, Take Care, Tommy's Midwives x
By Emma (not verified) on 11 Oct 2018 - 15:46
Thank you so much for the response - I was aware of the issue for babies but wasn't sure on pregnancy. Will continue with my honey on toast! :)

I'm 23 weeks pregnant and had a Chinese takeaway last week. I ordered a chicken dish and ate away, then noticed a substance at the bottom and side of the plate which the waitress said was dried shrimp - I don't know if it's a seasoning or an ingredient. It wouldn't have been hot and I understand that dried shrimp isn't cooked and I'm now worried about toxoplasma and listeria. Is there any reason to be worried? I haven't been ill following the food on Saturday night.
By Midwife @Tommys on 9 Oct 2018 - 12:43
Hi Sophie, If you haven't been unwell there is nothing to worry about. A Shrimp is a small sea animal. Sometimes you get chicken and shrimp in a mixed dish at a chinese take away.

To be added to the top of the list, as scandalously, women (and even doctors an midwives!) in this country are not informed: DO NOT share food with your toddler or eat of his plate/with his utensils. You risk contracting CMV with possibly devastating effects (about 200 cases a year in the UK). This risk is far more acute than, say, from eating blue cheese or parma ham, and it should be high on every list.
By Midwife @Tommys on 17 Sep 2018 - 16:05
Thank you for your comment. We are in the process of publishing our information about CMV. It will be available shortly. It is a good idea to mention it on the 'foods to avoid' page as well as this will highlight the risks. All of our information goes through a system of checking and therefore takes time before publishing, but you can be assured that your comment has been noted and taken on board. Many thanks

hello! i just want to ask some more question if this kind of a symptoms of being pregnant. when i eat breakfast,, lunch, and dinner, i feel full... and also, i can't understand of my feelings. in morning,, i feel sick and in evening, i feel so good... is this really apart of being pregnant?
By Midwife @Tommys on 13 Sep 2018 - 10:58
Hi Letty, Thank you for your comment.
Pregnancy sickness can occur at any time of the day and it is different for everyone. If you are feeling sick in the morning try and eat a light breakfast and then as you start to feel better though the day increase what you are eating but maintain a health diet and drink plenty of fluids. Hope this helps, Take Care, Tommy's Midwives x

I was a week late on my period but when I come on it was only light bleeding with no cramps at all which isn't normal for me I'm normally in that much pain I can't walk but this month has been different I feel a weird feeling in my belly like there's something there but I'm worried If I am pregnant I have been drinking energy drinks and smoking I haven't took a test yet tho
By Midwife @Tommys on 11 Sep 2018 - 12:50
I would advise that you take a pregnancy test to confirm if you are pregnant or not.If you are pregnant, you should contact your GP or maternity unit for a referral to the unit so that you can start pregnancy care.
It's very common for women to have smoked or drunk energy drinks before they found out that they were pregnant if not planning a pregnancy, but it would be sensible to stop these if you now think you might be pregnant. You may want to think about stopping smoking and use of these drinks for your general health even if not pregnant

Am entering my second trimester now, but at my early stage, I tried taking some pills to about the baby because I feel scared but i can bleed a little and it will stop, I took it like three times but it did d same thing. Then I went for scan only to find out that my baby is still there so am now scared whether those drugs are going to affect my baby. Please help, what do I do.
By Midwife @Tommys on 7 Sep 2018 - 12:46
I am sorry to hear that you have been through such a difficult time. The drugs that you took are unlikely to have affected the baby, however do the health professionals who are caring for you know about the medication that you took? If not is important to let them know so they can monitor the baby. If you are still considering the terminating the pregnancy then do speak with your GP or midwife for support with this and considering your options.

Sorry this is not linked to the article but I have just found out I am pregnant with my 3rd child. I am due to run a half marathon a week tomorrow. I am an experienced runner and have run several marathons and half marathons, I also ran in both my previous pregnancies but not in organised races. Will I be ok to take part in the half marathon. I find the advice around pregnancy and exercise very confusing.
By Midwife @Tommys on 31 Aug 2018 - 15:44
The advice around exercise is always to listen to your body and continue to do what you are use to doing. We would suggest to avoid running full marathons but if you are used to running and are comfortable doing a half then go for it!

By Midwife @Tommys on 24 May 2018 - 09:18
We are so sorry to hear about the loss of your little one, we cannot even begin to imagine what you have been going through and it is understandable that you are anxious in your next pregnancy. There is a lot of support that you will be offered and feel reassured that you will be monitored very closely in this pregnancy. Tell your midwife or GP how you are feeling, they will be able to tell you about support that is available in your area, maybe talking therapies or support groups so that you find ways of managing your worries . The good thing is that you are talking about it and asking for help, this is the first step. You can always email us on [email protected] or call 0800 0147 800 Monday to Friday 9am - 5pm if you want any support or help during this pregnancy. Hope this helps, Take care, Tommys' Midwives xx

I usually love papayas and i wanted to know if these are safe to consume in the first trimester? This is my first pregnancy.
By Midwife @Tommys on 26 Apr 2018 - 16:02
Hi Nadila, Thank you for your comment.
There is little research that has been done in this area of the safely of papaya consumption in pregnancy and from what is out there, there may be a possible link to contractions with unripen papaya. With this said, as there needs to be further research done in this area it would probably be advisable to avoid papayas as the information is limited. Hope this helps, Take Care, Tommy's Midwives x

I have two children. First child was delivered via c section premie. 32 weeks. Second child was difficult pregnancy with gestational diabetes and failed vbac. So emergency c section was preformed and i had uterine rupture. Now with third unplanned age becomes a factor because i am 36. Should I anticipate an even more difficult pregnancy or is there hope for a good pregnancy and healthy baby?
By Midwife @Tommys on 19 Apr 2018 - 14:09
Hi, Thank you for your comment.
As you have had medical issues in your last pregnancies with a premature birth and the gestational diabetes, this will place you in a high risk category and you should expect to be under consultant led care. This doesn't necessarily mean that you won't have a normal straight forward pregnancy, but you will expect to be monitored more closely in this pregnancy and if there are any signs of what happened in your previous pregnancies then they Doctors can treat you quicker.
Make sure you attend all your antenatal and hospital appointments as well as all your scans, this way you can be monitored closely. If you have any more questions then please contact the Tommy's Midwives by email on [email protected] Hope this helps, Take Care, Tommy's Midwives x

So I'm feeling very anxious as I have been trying for a couple months now. I was to receive my period on 4/1/18, usually always the beginning of the month, sometimes a couple days beforehand.
This month so far I have not received my full period, only spotting which was on 4/1, 4/2, and 4/3 nothing.
I took a test because I wanted the waiting to stop.....but the test was negative.
Do you think I should wait longer? If so how long?
By Midwife @Tommys on 6 Apr 2018 - 11:53
A pregnancy test would normally detect a pregnancy by the time of your missed period, how occasionally for some women it is a little later than this. If you are feeling very anxious then it may be worth seeing your GP for a blood test which is more accurate than a urine test. If you are trying for a pregnancy, if you are not already, we would advise for you to be taking a folic acid supplement.
Best wishes, Tommy's midwives
