A fridge with mould inside of it


Mould can be a serious health hazard, so it is important to regularly clean your fridge to ensure that it remains hygienic and free from harmful contaminants. Once it starts growing in food storage areas, you may be discarding food and spending more money on food than you should.

At ICE Cleaning, we can discover the root cause of mould in your fridge with our mould remediation services. Our technology and industrial-grade solutions allow us to identify the type of mould in your fridge, eliminating it and preventing its return in the future.

Read on to learn how to take control of mould and remove the spores for good.

Understanding mould and its implications for refrigerator hygiene

Mould in your refrigerator can pose real threats to food safety and the health of your appliance. The most common culprits of this are Aspergillus, Penicillium, and Cladosporium, which we have previously explored in a guide.

Your refrigerator can develop into a miniature ecosystem where humidity levels are high enough to provide a welcoming environment for mould growth. Under the right circumstances, mould has the ability to rapidly develop in an ideal area, even within a colder environment.

Mould can cause your cooling system to work harder, increasing energy bill costs. Therefore, maintaining cleanliness and prolonging the lifespan of your food is integral.

The science of mould growth in cold environments

It may be surprising, but your refrigerator can harbour mould spores, providing leftover food and water seepage.

Spores enter your fridge by attaching themselves to warm air as you open and close the door, resulting in the clash between the cold internal air and the warm external air, creating condensation, which is ideal for mould.

Mould does not require heat to thrive; it merely requires a bit of moisture and something to consume. Some types of mould can grow happily inside your refrigerator despite the lower temperature.

Preventative measures to stop mould growth

To prevent mould growth in your fridge, start by reducing the humidity and controlling the temperature.

Some products act as dehumidifiers for your fridge, which may help with this issue. A DIY alternative is to place an open box of bicarbonate soda in the fridge to change monthly. Other things you can do include:

  • Checking the door seal for any tears or damage
  • Ensuring the fridge temperature is 4°C to 5°C
  • Not leaving the fridge door open for too long
  • Letting food cool before placing it in the fridge
  • Ensuring you store food and liquids in refrigerator-safe containers

The role of refrigerator maintenance in mould prevention

The proper maintenance of refrigerators plays a critical role in preventing the growth and spread of mould. Mould thrives in moist environments, making the interior of a refrigerator a prime location for it to develop. Regular cleaning and maintenance can reduce the risk of mould growth. 

One of the steps in preventing mould is to keep the refrigerator clean and dry. Maintaining a mould-free refrigerator requires continuously cleaning the inside using an anti-mould solution and responding quickly to any messes or water seepages.

In addition to cleaning and temperature control, you must maintain proper airflow within the refrigerator. You can do this by not overpacking the refrigerator and ensuring that items are correctly spaced, allowing for proper ventilation. 

By following these simple maintenance guidelines, individuals can significantly reduce the risk of mould growth within their refrigerators.

Regular cleaning, proper temperature control, and adequate airflow are essential in mould prevention, protecting both the longevity of the refrigerator and the health of those who use it.

Safe food practices to minimise mould risk

Practising safe food handling and storage practices in your kitchen can help reduce the risk of mould development and ensure the safety of those consuming the food. 

Proper food storage is crucial to ensuring that mould growth does not occur. To achieve this, use airtight containers to maintain freshness and avoid moisture accumulation.

Additionally, frequently inspect and dispose of any expired or damaged food supplies to decrease the possibility of mould development.

Proper handling techniques are also essential in reducing the risk of mould growth. This includes washing hands thoroughly before handling food and using separate cutting boards and utensils for raw and cooked foods.

Cross-contamination is a significant risk factor for mould growth, so it is important to ensure proper food handling.

Proper cooking techniques are also essential in reducing the risk of mould growth. Cooking food to the appropriate temperature can help kill any bacteria or mould that may be present, minimising the risk of contamination.

Properly reheating leftovers is also important, as improperly reheated food can provide a breeding ground for mould and bacteria.

By following these guidelines, individuals can minimise the risk of mould growth and ensure the safety of those who consume their food. Proper storage, handling, and preparation techniques are key components in safe food practices and reducing the risk of mould and bacteria.

Implementing a fridge hygiene routine

Staying on top of fridge cleanliness can prevent any surprise mould growth. Start by marking your calendar for a weekly fridge inspection; this will be your regular defence against mould infestation.

Clean shelves and drawers with eco-friendly cleaning solutions to maintain freshness. These cleaners are kind to the planet and tough on grime.

You should rotate any food leftovers and check dates often. If you spot mould, you must seek help from specialists who know how to eliminate mould.

Recognising when professional help is needed

In certain instances, it is possible to come across mould that overcomes all your preventative measures. In such cases, we recommend that you seek out professional assistance. 

If you happen to stumble upon mould, it is important that you do not attempt to handle it on your own. Certain varieties of mould can cause severe illness when aggravated.
