Don't do it again: keeping food in plastic containers in the fridge can make you sick

What nobody tells you about what really happens when you put hot food in the fridge and how it can affect you

We've all been in a hurry to store leftovers. It's tempting to put that freshly made stew straight into the fridge, but this can be a serious mistake. Putting hot food directly into the refrigerator raises the internal temperature.

This breaks the cold chain of other foods and forces the motor to work harder to keep the right temperature. The problem isn't just with the refrigerator. The main risk is to your health.

Sudden temperature changes encourage the growth of bacteria like salmonella or listeria. These bacteria can cause food poisoning, especially in children, the elderly, or people with weakened immune systems.

Consequences for food

Storing hot food in containers also alters its flavor and texture. Soups, stews, pasta, or rice can change in flavor if they cool down too quickly inside the refrigerator.

In addition, the steam they release creates moisture. This moisture not only affects the flavor, but also makes it easier for mold to appear.

Even the refrigerator itself can suffer damage. The motor works harder to compensate for the heat, increasing electricity consumption and reducing its efficiency. In the long run, this can shorten the appliance's lifespan.

Best practices for storing food

The key is patience. Wait for the food to cool to room temperature before storing it. A good rule is to let it sit for at least two hours.

If you need to cool large amounts, divide the food into smaller, shallow containers. This speeds up cooling and reduces risks.

It's also recommended to use glass or stainless steel containers. These materials prevent cross-contamination and absorb fewer odors than plastic.

If you're in a hurry, there's a very useful trick: the reverse bain-marie. Place the container with hot food inside another container with cold water and ice. This cools the food quickly and safely without damaging the refrigerator.

Extra tips to keep your fridge healthy

Always keep the refrigerator clean. It's not just about hygiene, but about preventing contamination and bad odors. Also make sure the containers are clean before using them.

Follow the rule of not putting hot food inside. It's a simple habit, but it protects your health, your food, and your appliance. With a little patience and organization, your kitchen can be much safer.
