Key Points
- Follow proper food handling: wash hands, utensils, veggies; refrigerate cold food; use cooked food within 12 hours; reheat to boiling point
- Pregnant women should avoid soft cheeses, deli meats, pre-packaged salads, pรขtรฉ, cold smoked/raw seafood, soft serve ice cream, and thick shakes due to contamination risks
- Excessive alcohol intake during pregnancy can harm fetal development, leading to complications like low birth weight and developmental issues
- Limit caffeine from tea, coffee, cola, energy drinks, and chocolate during pregnancy to reduce potential risks, opting for decaf alternatives when possible
Pregnancy is a critical period where dietary choices can significantly impact both maternal and fetal health. Australian health authorities, like the Department of Health, have outlined clear guidelines to mitigate risks associated with foodborne illnesses such as listeriosis, which, although rare, poses a severe threat to pregnancy outcomes.
Listeriosis, caused by the bacteria Listeria monocytogenes, can lead to miscarriage, stillbirth, or severe illness in newborns. The bacteria can contaminate various foods, emphasising the importance of cautious food handling and consumption practices.
Essential Food Handling Practices
To reduce the risk of listeria contamination, follow these simple yet effective practices:
- Wash hands and utensils thoroughly before food preparation.
- Clean raw vegetables meticulously.
- Store cold foods in the refrigerator promptly.
- Consume cooked foods within 12 hours.
- Always reheat food to boiling to kill any harmful bacteria.
Foods to Avoid When Pregnant
Raw or Undercooked Seafood
Risk: Raw fish, particularly in dishes like sushi or sashimi, can carry harmful bacteria or parasites such as listeria or salmonella.
Updated Advice: While sushi-grade fish is flash-frozen to kill parasites, itโs best to avoid raw fish altogether due to contamination risks. Opt for fully cooked seafood or vegetarian sushi options.
Unpasteurised Dairy Products
Risk: Soft cheeses like brie, camembert, feta, and blue cheese made from unpasteurised milk can harbor listeria, which poses severe risks to your baby.
Updated Advice: Always check labels to confirm pasteurisation. Safe alternatives include hard cheeses and pasteurised versions of soft cheese.
Deli Meats and Cold Cuts
Risk: Pre-packaged or deli-counter meats can contain listeria or toxoplasmosis-causing parasites.
Updated Advice: Heat deli meats until steaming hot before consuming, and store them safely in the fridge, consuming within two days.
Raw or Undercooked Eggs
Risk: Raw eggs can be contaminated with salmonella, which can lead to food poisoning.
Updated Advice: Avoid foods containing raw or partially cooked eggs, such as homemade mayonnaise, mousse, or hollandaise sauce. Choose pasteurised egg products for safer options.
Raw Sprouts
Risk: Alfalfa, clover, mung bean, and radish sprouts can harbor bacteria that grow in warm, humid environments.
Updated Advice: Cook sprouts thoroughly or avoid them altogether to eliminate bacterial risks.
High-Mercury Fish
Risk: Fish such as shark (flake), swordfish, marlin, and large tuna have higher mercury levels, which can harm your babyโs developing nervous system.
Updated Advice: Opt for low-mercury fish like salmon, trout, and sardines, and limit consumption to 2-3 servings per week.
Unwashed Fruits and Vegetables
Risk: Pesticides and bacteria, including toxoplasma, can linger on produce.
Updated Advice: Wash all fruits and vegetables thoroughly under running water, even those with skins you plan to peel.
Foods High in Artificial Sweeteners or Additives
Risk: While artificial sweeteners like aspartame are generally considered safe in moderation, excessive consumption can lead to unnecessary risks.
Updated Advice: Use natural sweeteners like honey or opt for whole, minimally processed foods to meet nutritional needs.

Alcohol Consumption During Pregnancy
The stance on alcohol consumption during pregnancy is clear: no amount is considered safe. Research, including studies cited by the Australian Department of Health, demonstrates that alcohol can significantly affect fetal development, leading to conditions such as Fetal Alcohol Spectrum Disorders (FASD).
These conditions are associated with intellectual disabilities, behavioral problems, and physical deformities. Even moderate drinking can increase the risk of miscarriage, low birth weight, and developmental issues. Thus, to safeguard against these risks, abstaining from alcohol entirely during pregnancy is recommended.
Caffeine Intake During Pregnancy
Caffeine, a stimulant found in coffee, tea, cola, energy drinks, and chocolate, requires cautious consumption during pregnancy. While large amounts of caffeine have not been conclusively linked to birth defects, Australian guidelines suggest moderation is key.
The Royal Australian and New Zealand College of Obstetricians and Gynaecologists recommends limiting caffeine intake to reduce potential risks, including low birth weight and miscarriage. Opting for decaffeinated alternatives is a wise choice to minimise caffeine exposure while still enjoying these beverages.
Conclusion
Navigating dietary choices during pregnancy is crucial for the health and well-being of both the mother and the fetus. By adhering to Australian health guidelines and avoiding high-risk foods, pregnant individuals can significantly reduce the risk of foodborne illnesses and adverse pregnancy outcomes.
Embracing a diet rich in nutrients and low in potential contaminants supports a healthy pregnancy journey, laying a strong foundation for fetal development and maternal health.
