Refrigerator maintenance and food safety storage guidelines

Proper refrigerator maintenance and food storage are essential for preventing foodborne illnesses and maintaining food quality. Ice buildup in refrigerators is not always a technical defect; it can often be caused by excessive cooling settings, improperly closed doors, or dirty seals. Users should check temperature regulators, door gaskets, and drainage systems before assuming a mechanical failure.

Regarding food safety, the World Health Organization recommends storing cooked and highly perishable foods at temperatures below 5 degrees Celsius. A survey by the Federal Institute for Risk Assessment (BfR) found that the average refrigerator temperature is 5.5 degrees, yet only half of respondents used a thermometer to monitor it. In Germany, approximately 100,000 foodborne illnesses are reported annually, though the actual number is likely much higher.

Effective storage also involves understanding which foods benefit from cold temperatures. While meat and dairy require refrigeration to slow bacterial growth, items like tomatoes, bread, and bananas can lose flavor or texture if stored incorrectly. For instance, tomatoes prefer temperatures between 12 and 16 degrees Celsius, and apples should be stored separately from bananas to prevent premature ripening caused by ethylene gas.
