Guidelines for food preservation focus on maintaining temperature stability to prevent spoilage. Recommendations include avoiding the refrigerator door for highly perishable items like milk, dairy, meat, and fish, as the door experiences significant temperature fluctuations. Instead, these items should be stored on the colder, more stable inner shelves. Specific advice for seafood suggests keeping fish fillets in airtight containers in the coldest part of the refrigerator, while whole fish should be kept in the lower section to prevent contamination. For fish not intended for consumption within two days, freezing is advised. Regarding freezer storage, maintaining temperatures at -18 °C slows microbial activity, though it does not sterilize food. While exceeding recommended durations may not make food dangerous, it can degrade taste, texture, and nutritional value. Recommended storage times include 3–4 months for raw ground meat, 1–2 months for sausages, 4–6 months for beef steaks, and 10–12 months for whole poultry. For fish, lean varieties like cod can last approximately 4 months, while fatty fish like mackerel are recommended for up to 3 months. It is also critical to distinguish between expiration labels. The phrase ‘use by’ (da consumarsi entro) refers to food safety and microbiological stability; these products such as fresh meat, fish, soft cheeses, prepared salads, and deli meats should not be eaten after the date. this date due to risks of undetectable pathogens like listeria or salmonella. In contrast, ‘best before’ (da consumarsi preferibilmente entro) refers to quality, meaning the food quality. Food marked with ‘best before’ may still be safe to consume after the date, though it may lose fragrance, crunchiness, or flavor. Proper management of these labels can reduce food waste; in Switzerland, the Federal Office for the Environment notes that correct usage can save individuals an average of 600 francs per year.
