Your Handy Guide To Food-borne Risks In Pregnancy

10
2025-10

Pregnancy already comes with plenty of things to think about- worrying over food safety shouldn’t be one of them. 


This handy guide makes it easy to see at a glance which foods are safe, which ones to avoid, and why. By keeping it on hand, you’ll have extra peace of mind knowing you’re making choices that keep both you and your baby healthy.


Key:

Red = Don't eat

Yellow = Eat with caution

Green = OK to eat


Meat, Poultry & Seafood

Processed/cured meats

Ham, salami, luncheon, chicken meat etc.

 Recommendation:  DON'T EAT unless thoroughly cooked to at least 75 °C and eaten soon afterwards

 Rationale:  Risk of Listeria contamination

Raw meat

Any raw meat, raw chicken or other poultry, beef, pork etc.

 Recommendation:  DON'T EAT

 Rationale:  Potential for Salmonella, Listeria or other pathogens

Poultry

Cold chicken or turkey, e.g. used in sandwich bars

 Recommendation:  DON'T EAT

 Rationale:  Cold storage and slow cooling increase bacterial risk


Rotisserie chicken

 Recommendation:  Purchase freshly cooked and eat while hot. Store leftovers in fridge and use within a day of cooking, reheat until steaming hot throughout (or to at least 75 °C)

 Rationale:  LISTERIA bacterial growth risk in cold leftovers


Home cooked

 Recommendation:  Ensure chicken is cooked thoroughly to at least 74 °C and eat while hot. Store leftovers in fridge and use within a day of cooking, reheat until steaming hot throughout (or to at least 75 °C)

 Rationale:  Avoid undercooking, bacterial growth in leftovers

Paté

Cold paté or meat spreads

 Recommendation:  DON'T EAT

 Rationale:  Often contain Listeria

Seafood

Raw seafood

 Recommendation:  DON'T EAT

 Rationale:  Risk of Listeria, parasites, other contaminants


Ready-to-eat chilled peeled prawns

 Recommendation:  DON'T EAT

 Rationale:  Risk of contamination from storage or handling


Cooked fish and seafood

 Recommendation:  Cook thoroughly to at least 63 ℃ and eat while hot. Store leftovers in fridge and use within a day of cooking, reheat until steaming hot throughout (or to at least 75 °C)

 Rationale:  Poor reheating or handling can lead to bacterial growth


A note on seafood and mercury:

Certain large, long-living predatory fish such as shark (flake), swordfish, marlin, tilefish and king mackerel tend to accumulate high levels of mercury over time. Mercury can cross the placenta and affect your baby’s developing brain and nervous system, so it’s safest to limit or avoid these fish during pregnancy.


Safer Fish Choices:

Most smaller or shorter-lived fish have low mercury levels and are a great source of omega-3 fats, which support your baby’s brain and eye development. Safe and nutritious options include salmon, sardines, trout, tilapia, herring, whiting, and canned light tuna.


Aim for 2–3 serves (150 g each) of low-mercury fish per week, but limit high-mercury fish to no more than one serve per fortnight, and don’t eat any other fish that week

Sushi

Store-bought

 Recommendation:  DON'T EAT

 Rationale:  Use of raw fish/meat increases risk of pathogens


Home-made

 Recommendation:  Don't use raw meat or raw seafood; eat immediately

 Rationale:  Delay or poor handling can allow bacteria to grow


Cooked meats

Beef, pork, chicken, minced meats

 Recommendation:  Cook thoroughly (to ≥ 74 °C), eat hot

 Rationale:  Undercooking may leave pathogens alive


Dairy & Eggs

Cheese

Soft and semi-soft cheese, e.g., brie, camembert, ricotta, fetta, blue etc.

 Recommendation:  DON'T EAT unless thoroughly cooked to at least 75 °C and eaten promptly

 Rationale:  These cheeses may carry Listeria


Processed cheese, cheese spreads, cottage cheese, cream cheese etc.

 Recommendation:  Store in the fridge, eat within two days of opening package

 Rationale:  Longer storage increases microbial risk


Hard cheese, e.g. cheddar, tasty cheese, parmesan

 Recommendation:  Store in the fridge, in sealed wrapping/container; use a clean knife every time you cut it

 Rationale:  Lower moisture and acidity limit bacterial growth

Icecream

Soft serve

 Recommendation:  DON'T EAT

 Rationale:  Possible contamination from raw dairy or poor hygiene


Packaged frozen ice-cream

 Recommendation:  Keep frozen until eating; eat frozen

 Rationale:  Freezing inhibits bacterial growth

Dairy

Unpasteurised (raw) dairy products

 Recommendation:  DON'T DRINK OR USE

 Rationale:  May contain Listeria and other pathogens


Pasteurised (e.g. milk, cream, yoghurt)

 Recommendation:  Check 'best before' or 'used-by' date; Follow storage instructions

 Rationale:  Spoilage or contamination if storage is poor

Custard

Store-bought

 Recommendation:  Check 'best before' or 'use-by' date. Can be eaten cold if freshly opened. Store leftovers in fridge and use within a day of opening, reheat until steaming hot throughout

 Rationale:  Risk from bacterial growth if left too long


Home-made

 Recommendation:  Cooked thoroughly and consumed promptly

 Rationale:  Growth of bacteria in cooling / storage

Eggs

Cooked egg dishes, e.g. fried eggs, scrambled eggs, quiche

 Recommendation:  Cook thoroughly to at least 71 °C and eat while hot. Store in fridge. Store leftovers in fridge and use within a day of cooking, reheat until steaming hot throughout (or to at least 75 °C). Don't use cracked or dirty eggs

 Rationale:  Raw or cracked eggs may carry Salmonella; longer storage after cooking increases microbial risk


Raw in food, e.g. home-made mayonnaise, aioli, chocolate mousse, cake batter, pancake batter

 Recommendation:  DON'T EAT

 Rationale:  High risk of Salmonella


Vegetables & Fruit

Salads

Pre-prepared or pre-packaged salads including fruit salad, e.g. from salad bars, smorgasbords

 Recommendation:  DON'T EAT

 Rationale:  Risk of Listeria contamination from handling or food prep


Home-made

 Recommendation:  Wash salad ingredients immediately before making and eating salads; store any leftovers sealed in fridge and use within a day of preparation

 Rationale:  Bacteria can multiply if stored too long

Fruit

Rockmelon/Cantaloupe

 Recommendation:  DON'T EAT

 Rationale:  Often linked to Listeria outbreaks due to porous exterior


Whole fresh fruits

 Recommendation:  Wash well before eating

 Rationale:  Can carry dirt, soil, and surface bacteria

Vegetables and herbs

Fresh vegetables and herbs

 Recommendation:  Wash well just before eating raw or wash before cooking

 Rationale:  Dirt, soil, surface bacteria, toxoplasmosis


Frozen vegetables

 Recommendation:  Cook (don't eat uncooked)

 Rationale:  Freezing doesn’t kill all pathogens

Bean sprouts

Alfalfa sprouts, broccoli sprouts, onion sprouts, sunflower sprouts, clover sprouts, radish sprouts, snowpea sprouts, mung beans and soybean sprouts

 Recommendation:  DON'T EAT raw or lightly cooked

 Rationale:  Sprouts have high risk of bacterial contamination


Other Foods / Dishes

Leftovers

Cooked foods

 Recommendation:  Store leftovers in fridge and use within a day of cooking, reheat until steaming hot throughout (or to at least 75 °C). 

 Rationale:  Bacteria can multiply in cooled food

Canned foods

Tinned fruit, vegetables, fish etc.

 Recommendation:  Store unused portions in the fridge in clean, sealed containers and use within a day

 Rationale:  Once opened, contamination risk increases

Stuffing

Stuffing from chicken or poultry

 Recommendation:  DON'T EAT unless cooked separately and eat hot

 Rationale:  Inside stuffing may not reach safe temperature

Soy

All soy products, eg, tofu, soy milk, soy yoghurt etc.
