Food Safety During Pregnancy
This information is aimed at helping you to eat safely during pregnancy without avoiding foods unnecessarily.
See the chart at the end for detailed information on foods from each food group
that are safe to eat or should be avoided.
Alcohol
Heavy drinking can be harmful to your baby, particularly during the early stages of pregnancy; however, the effect of low to moderate drinking is less clear. Not drinking alcohol is the safest option.
Caffeine
Large amounts of caffeine may increase the chance of miscarriage or low birth weight. It is recommended that pregnant women limit caffeine to 200 mg per day.
This is the amount contained in:
- one to two cups of espresso coffee
- two to three instant coffees
- three to five cups of tea (depending on strength), hot chocolate or cola drinks.
Some energy drinks such as Red Bull and V contain caffeine or guarana (a source of caffeine) and are not recommended for pregnant women.
Mercury in some types of fish
Fish contain nutrients that are beneficial for pregnancy but there are six types of fish that you should limit due to their mercury content. These are shark (flake), marlin, broadbill, swordfish, orange roughy (also called deep sea perch) and catfish. See the chart below for more information.
Most types of fish are safe and are a good source of omega 3 oils which are beneficial for brain and nervous system development of the baby. Fish are also a good source of iodine. One to three serves a week are recommended. Snack sized tins of tuna and salmon contain less than half a serve and it is safe to have several of these per week. Other types of seafood such as shellfish and crustaceans (e.g., prawns, shrimps) generally contain lower levels of mercury and don’t pose a risk unless you eat large amounts often.
Vitamin A and liver
Limit liver to very small amounts, no more than 50 grams a week, as it contains high levels of a form of vitamin A called retinol which may be harmful to the developing baby. There is no danger of too much vitamin A from other foods.
Pregnancy multivitamins contain a type of vitamin A called beta carotene that is safe even in high doses. Multivitamin supplements that are not designed for pregnancy may contain retinol. Check with your pharmacist if in doubt.
Food contamination
Some types of food poisoning organisms can cause problems during pregnancy. The risk can be minimised by good hygiene and food handling practices and avoiding high risk foods.
Listeria
Listeria bacteria can contaminate food and cause listeriosis which is a flu-like infection. In pregnancy this infection can be passed on to the baby and can cause miscarriage, stillbirth or premature birth. Listeria infection is not a common problem and the risk can be reduced by following these tips:
- Eat freshly prepared foods where possible.
- Avoid refrigerated, ready to eat foods that may have been stored for long periods.
- Ensure good hygiene and clean utensils when preparing food.
- Thoroughly wash raw vegetables and fruit.
- Avoid foods such as pate, cold cooked chicken and deli meats such as ham and salami unless reheated to high temperature e.g., on a pizza.
- Avoid coleslaws, salads and fruit salads unless you are sure they have been freshly prepared.
- Avoid soft cheeses (e.g., brie, camembert, ricotta, feta, blue cheese) soft serve ice-cream and unpasteurised dairy products. Soft cheeses in cooked dishes are safe.
- Avoid uncooked or smoked seafood and pre-cooked prawns. Freshly cooked seafood and canned seafood is safe.
- Listeria is killed by thoroughly cooking food. Reheat foods to steaming hot.
Salmonella
Salmonella food poisoning can cause nausea, vomiting, diarrhoea and fever and in rare cases miscarriage. Raw or undercooked (runny) eggs are risky foods for salmonella. Avoid using eggs with cracked shells or foods containing raw eggs.
Sesame seeds are also a salmonella risk so avoid eating sesame seeds and ready to eat products such as tahini, halva and hummus. Sesame seeds that have been heat treated are safe to eat.
Toxoplasmosis
Toxoplasmosis is an infection that can cause brain and eye damage in the baby. It can be carried by raw meat and cats’ faeces. Thoroughly cook meat, wash vegetables, wear rubber gloves if handling cat litter and wash hands after gardening or handling pets.
Good food handling practices
- Wash hands before preparing foods or eating
- Use separate, clean chopping boards to prevent cross contamination of raw and cooked foods
- Make sure cooked foods are thoroughly cooked
- Don’t leave foods to cool too long on the bench. Put them in the fridge as soon as they stop steaming
- Don’t eat food that is meant to be in the fridge if it has been left out for more than 2 hours
- Eat leftover foods within 24 hours and reheat foods to ‘steaming’ hot
- Keep the fridge clean and below 5 degrees
- Cover stored foods
- Thaw frozen food in fridge or microwave, not at room temperature
- Store raw meat below other foods so that there is no chance that it will drip onto them
- Store eggs in the fridge
- Follow best before and use by dates and storage instructions. If in doubt throw it out.
Avoid at-risk foods
It is important during pregnancy to be aware of foods which may cause you and your baby problems. See the table below for details of which foods are safe to eat during pregnancy and those that you should avoid.
