Refrigerators are essential kitchen aids for preserving food in every home. However, misuse, such as overstuffing and neglecting regular cleaning, can transform refrigerators into bacterial breeding grounds, directly threatening the health of the entire family.

Overstuffing the freezer compartment

Associate Professor Doctor Nguyen Duy Thinh, from the Institute of Biotechnology and Food at Hanoi University of Science and Technology, states that freezing is an effective method to maintain the nutritional value, quality, and flavor of many foods. Nevertheless, storage duration depends on various factors, including temperature, meat type, whether it is raw or processed, and if it is a whole cut or minced.

The ideal storage temperature is a stable -18°C or below. If stored for too long, food will inevitably degrade, produce toxins, harm the digestive system, and increase the risk of infection and food poisoning.

When a refrigerator is overstuffed, cold air cannot circulate evenly. This causes food to spoil faster and increases the risk of cross-contamination.

Not discarding moldy food

Many people have a habit of scraping off mold from bread, vegetables, or rice and then consuming the remaining portion. In reality, refrigerators cannot completely eliminate mold. Foods with high moisture content are particularly susceptible to deep mold penetration, which can cause digestive harm.

Consuming incorrectly stored overnight food

Leftover food left at room temperature for too long becomes a breeding ground for bacteria. Green vegetables or soup, if left overnight, can produce nitrites. When ingested, nitrites can convert into nitrosamines, a compound directly linked to stomach cancer if accumulated long-term in the body.

Experts recommend cleaning food under running water and draining it before freezing. Portion food into single-use amounts to avoid repeated thawing and refreezing. Store meat in specialized food wraps or airtight containers, not in regular plastic bags. Absolutely do not stack frozen meat with fresh meat, and avoid placing wet bags of meat directly into the freezer.

Arrange containers neatly and label them with the storage start date to ensure a first-in, first-out usage. It is crucial not to store raw and cooked meat together.

Regularly clean the refrigerator and inspect food items to discard anything expired or showing signs of spoilage. Do not keep cooked food for too long. Prioritize consuming cooked food within 24 hours and avoid reheating it repeatedly. Fresh seafood should be prepared immediately or frozen properly if not used right away.

If food shows signs of mold, discoloration, spoilage, or an unusual smell, discard it completely. Do not let the desire to avoid waste compromise the long-term health of your family.

Regularly check the expiry dates and condition of opened spice jars. Purchase only enough food for a few days, store it correctly, and use it promptly to safeguard your health.
