Moldy food in the fridge? Here’s what you should do.

Why does mold grow so easily in the refrigerator?

Humidity is certainly the main factor, but lack of proper ventilation also plays a crucial role. When the refrigerator is too crowded or too warm (above 4°C), the air doesn’t circulate properly, which encourages condensation and the growth of mold spores.

Other factors that promote mold growth:

1. Cross-contamination : If moldy food comes into contact with other foods, the spores spread easily. Even a small piece of mold can contaminate everything else.

2. Momentary Heating : Every time you open and close your refrigerator, especially in summer, the interior temporarily heats up, creating a perfect environment for mold, especially if the refrigerator is not cold enough.

How to prevent food from going moldy in the fridge:

Your advice is already very valid, but you could add some tips that make the difference:

1. Airtight containers and wrapping food well:
   Using airtight containers not only prevents moisture and air from coming into contact with food, but also helps keep food fresh longer. If you don’t have airtight containers, a good alternative is to wrap food in plastic wrap or aluminum foil .

2. Optimal temperature (4°C or lower)
   Check your refrigerator’s temperature with a refrigerator thermometer. It may seem trivial, but often the refrigerator’s internal thermostat isn’t perfectly accurate.

3. Regular cleaning:
   A clean fridge is a healthy fridge. Weekly cleaning helps remove any traces of food that could become a breeding ground for mold. Use water and vinegar to disinfect surfaces, avoiding harsh products that could contaminate food.

4. Paper towels in the drawers:
   Placing some paper towels in the crisper drawers is a great way to absorb excess moisture. Change them regularly to prevent them from becoming waterlogged.

5. Don’t overload your refrigerator.
   It’s true, the refrigerator shouldn’t be overcrowded, otherwise the air won’t circulate properly. Always leave some space between foods to allow proper circulation of cold air.

6. Freezing fresh foods
   If you’re not sure you’ll be able to use a food in time, consider freezing it . Vegetables, fruit, and even bread keep well in the freezer and can be thawed when needed.

7. Check expiration dates:
   Check fresh foods regularly and consume them before they expire. It may seem trivial, but sometimes just moving a food to a more visible spot in the fridge is enough to remind you to use it.

What to do if you find moldy food:

1. Discard contaminated food : If a food is visibly moldy, it’s best to discard it entirely. Simply removing the moldy portion isn’t enough, as the spores have already spread throughout the entire food.

2. Isolate contaminated food : If moldy food has been placed near other foods, immediately separate any foods that may be contaminated.

3. Remove any mold from the fridge : After removing moldy food, immediately wipe the fridge with a damp cloth to remove any mold.

4. Ventilation : If possible, leave the refrigerator door open for a few hours (without any food inside) to allow air to circulate. This can help reduce internal humidity.

Small extra precautions:

• If you have foods that tend to go moldy quickly (like fresh cheeses, bread, or fruit), try vacuum- sealing them . This system is excellent for preventing moisture contamination.

• Fruits and vegetables can develop mold quickly, so it’s best to keep them separate and in air-permeable containers. If possible, consume the ripest fruit first.
