Keep eggs in the refrigerator at home until you need them, even if you bought them from an unrefrigerated shelf. Choose clean, uncracked eggs and follow the date and storage instructions on the carton. If an egg has a cracked shell before you are ready to cook it, discard it.
Cook eggs until both the white and yolk are firm to reduce the risk of food poisoning. Singapore Food Agency advises particular care with raw eggs for young children, pregnant people, older adults and people with weakened immune systems. Keep cooked egg dishes cold if you are saving them for later.
- Choose clean eggs with uncracked shells and check the pack date.
- Store eggs in the refrigerator and take out what you need for cooking.
- Wash your hands with soap after handling raw eggs and keep raw eggs away from ready-to-eat food.
- Cook until the whites and yolks are firm for a safer everyday preparation.

Section 1 of 5 · Start before the carton goes in the fridge
Buy and store eggs for everyday use
At the shop, check the packaging and look for clean, uncracked shells where you can see them. At home, put the eggs in the refrigerator until you need them. Keep the carton information available so anyone cooking can check the date and instructions. Singapore’s guidance on egg handling recommends refrigerating raw shell eggs and discarding cracked ones. Singapore guidance on handling eggs
| Situation | What to do |
|---|---|
| Shell is clean and intact | Refrigerate and follow the carton instructions |
| Shell was already cracked in storage | Discard the egg |
| You are about to prepare a meal | Take out the eggs you need and put the rest back |
| A recipe calls for raw egg | Consider a suitable pasteurised egg product and follow its directions |
| An egg dish is being saved | Refrigerate promptly below 4°C and follow applicable storage guidance |
If someone transfers the eggs to a different container, keep the carton date or mark it on the container. When two purchases are in the fridge, keep them separate so the newer batch does not obscure the date of the older eggs.
Section 2 of 5 · Keep cooked food on a separate plate
Handle the shell and raw egg carefully
Salmonella can be on the shell or inside an egg. Appearance alone cannot tell you whether it is present. Wash your hands with soap before and after handling eggs. Keep shells and utensils that touched raw egg away from bread, fruit and cooked ingredients. Clean the work area after cracking eggs. Singapore Food Agency’s guide to raw egg safety
Make the workflow easier
If you are making egg sandwiches, get the bread and serving plate ready before you handle the eggs. Use clean utensils after the eggs are cooked. This is particularly useful when several people are preparing breakfast together or one person is packing a child’s school snack.
What if a shell cracks before cooking?
If you find a crack on an egg that has been sitting in the carton or during transport, discard it. Deliberately cracking an egg straight into a pan or bowl as part of cooking is a different situation. Keep it separate from ready-to-eat foods and proceed with the recipe safely.

Section 3 of 5 · Choose the preparation and timing
Cook eggs for the people eating them
SFA advises cooking eggs until the yolk and white are firm. If you are making porridge or noodles, cook the egg thoroughly rather than relying on residual heat in the bowl. For a sandwich, prepare the egg fully and use clean utensils to assemble the food.
What about kaya toast and soft-boiled eggs?
Soft-boiled eggs are a familiar Singapore breakfast. SFA explains that controls reduce the risk but advises consumers to avoid raw eggs, especially in more vulnerable groups. Order or prepare fully cooked eggs when you want the lower-risk choice. If a recipe uses raw or lightly cooked eggs, SFA suggests considering pasteurised eggs. Check that the product is suitable for the recipe. SFA’s advice on raw and lightly cooked eggs

Section 4 of 5 · Think about when the egg will be eaten
Plan storage after cooking
Serve cooked eggs and egg dishes promptly. If saving food containing eggs, refrigerate it promptly below 4°C as advised by SFA. An ordinary school bag cannot keep an egg sandwich chilled for hours. Use reliable cold storage or buy the sandwich closer to the eating break. If you cannot keep the food chilled, pack a suitable shelf-stable snack instead.
If a family makes breakfast and school sandwiches at the same time, prepare the packed food only when you can keep it cold from the kitchen to the break. A plan for the fridge at the destination is useful only if the food stays cold on the journey too.
After-school snack ideas and storage choices
Decide who will eat the leftover portion
If you cook extra eggs, decide before the meal whether the remaining portion is for later that day or for a packed meal. Keep it separate from food left on the table, put it into a clean covered container and refrigerate it promptly. If someone cannot confirm how long a cooked egg dish sat out, do not use appearance alone to judge it. SFA’s guide to temperature control for cooked food

Egg storage questions
Can I rely on the smell or float test?
Those checks cannot tell you whether an egg contains Salmonella. Check the shell, date and storage history, and cook the egg properly.
Can I keep the eggs on the counter because the shop did?
Refrigeration is the recommended home storage choice. Follow any instructions provided with the pack.
How should I handle liquid egg?
Follow the label closely, including refrigeration and use after opening. Storage instructions for liquid egg differ from those for intact eggs.
Can I pack a cooked egg with lunch?
Yes if you can keep it appropriately chilled until eating and the food suits the school’s rules. If cold storage is uncertain, choose a suitable alternative.
