Eggs are a staple in most UK households, used for everything from scrambled eggs to baking. However, many people store them on the kitchen worktop, which can lead to spoilage, especially during summer. Experts now advise refrigerating eggs to keep them safe and fresh for longer.
Why Refrigeration Matters
In the UK, eggs are typically sold without refrigeration because supermarkets do not wash off the natural protective coating, or bloom, on the shell. This bloom acts as a barrier against Salmonella. However, when temperatures rise in June, heat can weaken the bloom, allowing bacteria to multiply and making eggs unsafe to eat sooner than expected.
Experts at Geldard Farm Eggs confirm that while room temperature storage is generally acceptable, the fridge is the "best place" for eggs. They state: "For maximum freshness, it's best to store eggs in the refrigerator at a steady temperature below 20°C. The consistent cool environment slows down the ageing process and helps maintain egg quality for longer."
Understanding Eggshells
Eggshells are not solid; they are covered in microscopic pores that allow a developing chick to breathe. The natural bloom protects against bacteria, but warm temperatures can cause this layer to dry out and deteriorate, increasing the risk of contamination. Heat also accelerates chemical changes in fats and proteins, making eggs lose freshness and become watery.
Proper Fridge Storage
Simply placing eggs in the fridge as soon as you return from the supermarket can significantly extend their shelf life and prevent spoilage. However, avoid storing eggs in the fridge door's egg tray, as temperature fluctuations when opening the door can cause condensation. Instead, keep eggs on the middle or lower shelf where the temperature is more stable.
It is also important to keep eggs in their original carton. This prevents moisture loss and stops eggs from absorbing strong odours from foods like onions or garlic.
Reducing Food Waste
Every year, UK households discard millions of pounds worth of food during warmer months due to improper storage. Understanding how to store eggs correctly not only reduces waste but also keeps groceries fresher longer, saving money.
