Foods to Avoid During Pregnancy: A Safe Eating Guide

Most foods are safe in pregnancy, and a short list needs care because of germs, parasites or too much of a nutrient. The main ones to avoid are raw or undercooked meat, fish and eggs, unpasteurised milk and its products, liver, some high-mercury fish, alcohol, and too much caffeine.

This guide explains why, shows the numbers from the NHS and CDC, and clears up common myths about papaya and pineapple. Rules vary between countries, so use it with your doctor's advice.

Why Food Safety Matters More in Pregnancy

Your immune system changes in pregnancy, so some food germs make you more ill. The CDC says pregnant women are about 10 times more likely to get a Listeria infection than other adults. Infections like this can affect the baby. The simple habits are to clean, separate, cook and chill food properly.

Meat, Eggs and Seafood

• Meat and poultry: cook until steaming hot with no pink meat or pink juices. Avoid raw or undercooked meat.
• Eggs: cook until the yolk and white are firm. The NHS allows raw eggs only if they carry a UK-specific safety stamp, so the simple rule is to eat fully cooked eggs. The CDC also advises avoiding raw batter and dressings made with raw egg.
• Liver and liver products: avoid them, because they contain very high levels of vitamin A that can harm the baby.
• Raw fish and shellfish: avoid sushi, sashimi and ceviche. Cook fish and shellfish well.
• Cold cuts and unheated deli meats: avoid unless cooked until steaming hot.

Fish and Mercury

Fish is useful in pregnancy, but some types carry too much mercury. The NHS says to avoid shark, swordfish and marlin. The CDC also lists king mackerel and tilefish. The CDC names shrimp, salmon, pollock, catfish and canned light tuna as lower-mercury choices.

The NHS limits tuna to no more than 4 cans or 2 steaks a week and oily fish such as salmon, mackerel and sardines to no more than 2 portions a week. Because limits differ by country and local fish species, ask your doctor which local fish are fine.

Milk, Cheese and Juice

• Avoid unpasteurised (raw) milk, and cream, yoghurt, butter or ice cream made from it.
• Choose pasteurised dairy. The CDC lists pasteurised hard cheeses and pasteurised cottage, cream, feta and mozzarella cheeses as safer.
• Avoid soft cheeses made from raw milk, and the NHS says soft mould-ripened and blue-veined cheeses must be thoroughly cooked.
• Avoid unpasteurised fruit juice. The CDC says to boil it for 1 minute or choose pasteurised juice.

Tip: check the label for the word 'pasteurised' when buying milk, curd, paneer or cheese from a shop. If you are unsure about loose milk, ask your doctor how to make it safe.

Fruit, Vegetables and Sprouts

Fruit and vegetables are very good for you, but they must be washed well to remove soil and germs. The CDC also advises avoiding raw or undercooked sprouts, such as alfalfa and bean sprouts, and cooking them until steaming hot. Cut melon should not sit out for more than 2 hours, or 1 hour in hot weather above 90 degrees Fahrenheit. This matters in Andhra Pradesh summers. See our guide to foods to eat during pregnancy for what to include.

Caffeine, Alcohol and Herbal Drinks

• Caffeine: the NHS advises no more than 200 mg a day. As a guide it gives about 100 mg for a cup of instant coffee, 75 mg for a cup of tea, 40 mg for a can of cola and 80 mg for a small energy drink. Other countries set different limits, so ask your doctor.
• Alcohol: the NHS advises avoiding it completely, because it can cause long-term harm to the baby.
• Herbal teas: the NHS says to limit them to 4 cups a day and avoid teas containing liquorice root.

Papaya, Pineapple and Other Food Myths

Many families advise avoiding papaya, pineapple or other 'heating' foods. The NHS and CDC lists of foods to avoid do not include ripe papaya or pineapple, and both say fruit should be washed thoroughly. The sources I read give no guidance on unripe papaya, which families commonly warn against. If you are unsure about a food your family has told you to avoid, ask your doctor rather than cutting out whole food groups.

• Myth: You must eat for two. Fact: quality matters more than quantity; see our pregnancy weight gain calculator for a guide.
• Myth: Nuts must be avoided. Fact: the NHS says peanuts and other nuts are fine unless you have an allergy or your doctor advises otherwise.

When to be cautious: if you eat something on the avoid list by mistake, do not panic, but tell your doctor, especially if you develop fever, vomiting or diarrhoea, which can be signs of food poisoning.

Safe Kitchen Habits at Home

• Wash your hands, boards and knives after handling raw meat, fish or eggs.
• Keep raw and cooked foods apart in the fridge and on the counter.
• Reheat leftovers until steaming hot, and do not leave cooked food out for long in the heat.
• Wash all fruit, vegetables and salads thoroughly before eating or cutting.
• Check use-by dates on packaged sandwiches, salads and cut fruit, and keep them chilled.

The NHS also advises using food only before its use-by date and keeping ready-prepared foods chilled.

When to See a Doctor

Call your doctor if you have a fever, repeated vomiting, severe diarrhoea, stomach cramps, or feel generally unwell after eating, or if you cannot keep food and fluids down for a day. Persistent vomiting may also be hyperemesis; read morning sickness remedies and treatment. Your antenatal check-ups are a good time to talk about diet.
