Eggs are a staple in most UK households, used for breakfast, pasta, baking, and more. However, as summer temperatures rise, improper storage can lead to spoilage and contamination. Experts warn that storing eggs on kitchen worktops during June can compromise their safety.
Why Eggs Need Refrigeration in Summer
In the UK, eggs are often kept at room temperature because supermarkets do not wash away the natural protective coating, or bloom, which helps prevent Salmonella. However, once temperatures climb in June, heat can weaken this barrier, allowing bacteria on the shell to multiply rapidly and making eggs unsafe to eat sooner than expected.
Specialists at Geldard Farm Eggs state: "For maximum freshness, store eggs in the refrigerator at a steady temperature below 20°C. The consistent cool environment slows ageing and maintains egg quality."
The Science Behind Eggshells
Eggshells are not completely solid; they have microscopic pores that allow a chick to breathe during development. The bloom normally shields against harmful bacteria, but warmer temperatures can cause it to dry out and deteriorate, increasing the risk of food-poisoning bacteria entering the egg. Heat also accelerates chemical changes in fats and proteins, causing eggs to lose freshness and become watery.
Proper Egg Storage Tips
Refrigerating eggs immediately after purchase can extend their shelf life by several weeks and prevent spoilage and flies. However, avoid storing eggs in the fridge door, as temperature fluctuations from opening the door can cause condensation and bacterial growth. Instead, place eggs on the middle or lower shelf where temperature is more stable.
Always keep eggs in their original carton to protect against moisture loss and absorbing strong odours from foods like onions or garlic. Britons discard millions of pounds' worth of food each year due to improper storage during warmer months. Understanding how to store eggs correctly reduces food waste, keeps groceries fresher longer, and saves money.
