As food prices continue to rise, households are seeking ways to reduce waste and save money by maximizing the shelf life of the groceries they buy. Experts emphasize that proper fridge organisation can play a key role in this effort, helping to prolong food freshness and avoid unnecessary disposal.
The average household reportedly throws away around £50 worth of food each month, according to the environmental charity WRAP (Waste and Resources Action Programme). Adjusting how food is stored inside the fridge and maintaining optimal temperatures can make a significant difference.
Inside the fridge, temperature varies depending on location. The door is the warmest spot due to frequent opening and exposure to outside air, making it unsuitable for highly perishable items like milk, butter, eggs, and fruit juices. These foods spoil more quickly in the door because bacteria multiply faster with temperature fluctuations, while light and oxygen can break down vitamins and trigger spoilage in juices. Instead, the door is best suited for stable products such as condiments—ketchup, pickles, and mustards—whose salt, sugar, and acid content protect them from bacteria and temperature changes.
The top shelf is warmer than the rest, as warm air rises, but it is recommended for cooked and ready-to-eat foods such as leftovers. Storing these items in smaller, sealed glass containers helps maintain stable temperatures and reduces contamination risk from raw foods below.
The middle shelf, slightly cooler, is optimal for dairy products including cheese, yogurt, and butter. Eggs are also best kept here in their original cartons to limit moisture loss and prevent absorption of strong odors. Placing perishable fruits like berries on the middle shelf at eye level can encourage their timely consumption and extend freshness by keeping them in their original packaging, which maintains humidity.
The coldest area is the bottom shelf, ideal for storing raw meat and fish. This placement helps inhibit the growth of harmful bacteria such as salmonella, E. coli, and campylobacter. To avoid cross-contamination, different meats should be stored separately, preferably in sealed containers. Experts also recommend using standalone fridge thermometers to regularly monitor temperature, as built-in dials may not always provide accurate readings. Adjusting settings is especially important during hot weather and frequent door openings, which can cause temperature fluctuations.
Fridge drawers provide a humid environment conducive to preserving delicate vegetables like spinach, lettuce, kale, and spring onions. Keeping fruits and vegetables in separate drawers is advised because some fruits, such as apples and avocados, emit ethylene gas that accelerates the ripening and spoilage of nearby vegetables. Adding a layer of kitchen towel in the drawers can absorb excess moisture, further prolonging produce life.
Certain items are better stored outside the fridge to maintain quality. For example, bananas turn black when chilled, basil leaves become slimy, and cold temperatures can cause cooking oil to thicken and turn cloudy. Onions and potatoes also spoil faster in the fridge because cold converts their starches into sugars, altering texture and taste; these should be kept in a cool, dark pantry or airy basket.
Additional tips to reduce food waste include establishing an “eat me first” area in the fridge for items nearing their use-by dates, allowing hot foods to cool before refrigeration to prevent raising the fridge’s internal temperature, and performing regular fridge cleanouts to avoid overcrowding. Tender herbs such as parsley, coriander, and basil are best stored upright in water like flowers, and leafy greens should be patted dry before storage to prevent moisture-related spoilage. Some wilted fruits and vegetables like carrots or rhubarb can be refreshed by soaking in ice-cold water for an hour.
Overall, these storage practices, combined with mindful temperature management and routine organisation, can help consumers reduce food waste, save money, and promote food safety in their homes.
