Food safety
in pregnancy
Pregnant women have lower levels of
immunity than usual and may be more at
risk of getting diseases carried by food.

                 This booklet provides advice and
                  guidance on what you can do to
                      avoid dangerous food bugs.

Higher risk foods
to avoid when pregnant
   • Chilled ready-to-eat foods such as those bought
     from a supermarket deli or restaurant buffet unless
     they are heated until piping hot.
   • Prepared ready-to-eat foods such as store-bought
     sandwiches where you can’t be certain of product
     age, storage conditions, or the preparer’s food
     handling practices.
   • Soft and semi-soft pasteurised cheese e.g. brie,
     camembert, feta, blue, mozzarella, ricotta.
   • Raw milk (unpasturised), raw milk cheeses and raw
     milk yoghurts.
   • Cold cooked or smoked chicken.
   • Processed meats such as ham, pâté, salami or
     luncheon.
   • Prepared salads including rice or pasta salad,
     coleslaw, roasted vegetable and green salads.
   • Raw or smoked seafood including sushi, smoked
     salmon, marinated mussels, or oysters.
   • Raw eggs e.g. in smoothies, mayonnaise or desserts
     like mousse.
   • Soft serve ice cream.
   • Cream or custard especially in pre-made cakes
     or pastries (unless newly opened or home-made
     and fresh).
   • Hummus and other dips containing tahini
     (which has been linked to both Salmonella and
     Listeria infection).

can do to prevent      Unlike most bacteria, Listeria can grow on food in the fridge.
                       The disease caused by Listeria – listeriosis – may cause
foodborne illness.     miscarriage or early labour or the baby may be born with the
                       infection and need treatment with antibiotics.

                          To avoid listeriosis:
                          • avoid eating higher risk foods (see box on inside
                            front page or pull-out guide)
                          • wash or cook food thoroughly
                          • keep to ‘use by’ and ‘best buy’ dates and store food
                            at the recommended temperatures
                          • eat packaged perishable foods within a couple of

Some other common foodborne
illnesses to watch out for:
Campylobacter is a bacterium commonly found in animals
and the environment. Campylobacteriosis is New Zealand’s
most commonly reported foodborne illness. In pregnancy it
may cause miscarriage and premature labour.

Salmonella is a bacterium quite commonly found in raw
meats, poultry, raw (unpasteurised) milk and raw milk
cheeses and yoghurts, seafood, fresh produce (including
sprouts), and foods such as kebabs and sandwiches handled
by infected foodhandlers. Salmonellosis is New Zealand’s
second most commonly reported foodborne illness. In
pregnancy it can cause stillbirth on rare occasions.

                                                                                           3

TOP TIP
Cook
• Defrost food in the fridge overnight or on the defrost
  setting in the microwave and make sure it’s defrosted right
  through before cooking.
• Preheat the oven so that food cooks as quickly as possible.
• Keep raw and cooked foods separate.
• Cook or reheat food thoroughly. Cook chicken, mince and
  sausages right through – the only way to be really sure is
  to use a meat thermometer to check they are cooked to
                                                                              Clean
  the safe internal temperature of 75°C.
• Marinate food in the fridge and cook the marinade before
  pouring it over cooked food.
• Eat cooked food while it is still hot – don’t leave it to stand
  at room temperature for more than two hours.
• Reheat leftovers until piping hot (over 70ºC) and do not
   reheat more than once.

Chill
• Fridges should be between 2ºC and 4ºC. If you
  overload the fridge or open it often, it will have difficulty
                                                                              Cook
  staying cold.
• Freezers should be between –15ºC and –18ºC ie, cold
  enough that the food is frozen solid.
• Cover food before putting in the fridge or leaving out
  for serving – food can be covered and left at room
  temperature for up to two hours before it should be
  eaten, reheated right through, put back in the fridge, or
  thrown out.
• Cover and store raw meat on the bottom shelf of the fridge
  so juices don’t drip on other food.                                         Chill

                                                                                      5

                      • Dry hands well on a clean, dry hand towel or paper towel.
                      • Keep hand towels for hands only, or use paper towels –
                        don’t use the tea towel.
                      • Use a fresh hand towel daily
                        (and change it more often if it is dirty).

                      Buy safe food
                      Food that has passed its “use by” date is not safe to eat and it
                      is illegal to sell it.

                          • hot foods that are not piping hot
                            (e.g. cooked chicken).

• Only drink treated water.

   Canned foods
   Other foods that are usually safe to eat are those that are shelf-
   stable (i.e. able to be stored in the pantry rather than the fridge)
   or canned. Shelf-stable foods can be kept unopened at room
   temperature for a long time and are not usually a risk for Listeria,
   provided they are stored and used as per the manufacturer’s
   instructions. Canned foods such as canned tuna and chicken
   receive heat treatment which removes bacteria, and the
   packaging will prevent others from growing. However, once the
   food has been opened, it is important to consume it immediately.

                                                                                                    7

prepared at home.     • Milk and milk products (e.g. milk, cheese, and yoghurt)
                        are important sources of protein and calcium during
                        pregnancy. Most milk products sold in New Zealand are
                        pasteurised, which greatly reduces the risk of bugs that
                        can make you sick. Ideally, they should be consumed
                        within two days of opening, or can be used as an
                        ingredient in cooked foods if older than two days. Don’t

                        yoghurts.
                      • Soft, pasteurised cheeses (e.g. brie, camembert, blue,
                        ricotta, mozzarella and feta) should generally not be eaten
                        uncooked while you are pregnant. However, if you’ve
                        bought them in the manufacturer’s original packaging,
                        they can be eaten in small quantities immediately after
                        opening. Do not reseal and eat them later, and do not
                        eat if they have been cut and repackaged in a deli or

In pregnancy you need more…

Folate is found     Folic acid
naturally in        • Before you get pregnant and during the first trimester of
                      pregnancy you need an increased amount of folic acid, a
food – especially     B vitamin which helps form your baby’s blood cells and
                      nerve tissue. If you don’t get enough folic acid your baby

                    • Folate is found naturally in food – especially green
                      vegetables and grains. Folic acid, which is the synthetic
                      form of folate, is voluntarily added to some foods,
                      e.g. some breakfast cereals and some bread. However, it
                      is hard to get enough folate or folic acid from your diet, so
                      the Ministry of Health recommends you take
                      a folic acid tablet.
                    • For at least four weeks before you conceive and for the
                      first 12 weeks of pregnancy you should take a registered
                      800 microgram folic acid tablet daily. Women with a
                      family history of neural tube defects may be advised to
                      take a higher dose of folic acid. Check with your doctor or
                      midwife to find out what is best for you.
                    • Folic acid tablets are available from pharmacies or on
                      prescription from your midwife or doctor. If you find out
                      that you are pregnant and have not been taking folic acid
                      tablets, you should start taking one immediately.

• A subsidised iodine-only tablet (containing 150 micrograms)
  specifically made for pregnant and breastfeeding women is
  available from pharmacies or on prescription from your doctor
  or midwife. Other iodine supplements (including seaweed
  and kelp supplements) are not recommended as the iodine
  content in some of these products is extremely variable and
  there are risks from having too much iodine.
• Care must be taken when choosing foods containing brown
  seaweed, such as kelp, kombu, wakame, quandi-cai,
  hiziki/hijiki, arame or Sargassum fusiforme which contains
  naturally high and varying levels of iodine. If brown seaweed
  is consumed regularly, the levels of iodine can be too high for
  pregnant and breastfeeding women. It is recommended that
  pregnant and breastfeeding women eat no more than one
  serve a week of brown seaweed.
• If you have any concerns about iodine intake, talk to your
  midwife or doctor about what is best for you and your
  baby.                                                                             11

Alcohol
It is safest to avoid alcohol during
pregnancy or if you are trying to get
pregnant. Alcohol crosses the placenta
so the foetus is affected by whatever the
mother consumes. Excessive alcohol
consumption is linked to foetal alcohol
syndrome, which may damage your
baby’s brain. Even if the mother drinks
only small amounts, her baby may show
behavioural and learning difficulties
linked to alcohol.
