The refrigeration equipment you use as a business owner is critical for keeping your products and preventing disease among your staff and customers. Unfortunately, certain conditions, such as the growth of mold, can affect the effectiveness and safety of your commercial refrigeration system.
Mold may develop almost anywhere where there is relative humidity, although it is far more frequent in situations where moisture levels are persistently high, such as commercial refrigerators.
With high levels of humidity that are essential for some perishable items, the unit becomes vulnerable to the growth of fungus (mold). The dangers of mold are very high. It is highly important to understand its impact in order to protect your system from it by performing commercial refrigeration check-ups.
Risks of Mold Growth
To make you fully understand the dangers that come along with mold growth, we have mentioned them in detail.
Health Dangers
Before starting your commercial foodservice business, you should know that any place or food that has mold needs to be discarded. This is advised because the fungus further produces mycotoxins. There is a type of poisonous chemical that is only produced by mold. A lot of health risks are attached to this poison, from food poisoning to death.
Moreover, mold growth might be quite dangerous to your employees. Mold spores can also include mycotoxins, and when produced during the seeding phase of the mold’s life cycle, they can become airborne. When mold is disturbed, such as when mold-covered boxes are moved or when you begin clearing out the mold in your walk-in cooler, spores are discharged.
Rashes, burning eyes, allergy symptoms, and the very significant health concerns of mycotoxin exposure can all result from mold exposure to a greater extent. Especially if you’re dealing with some of the more hazardous molds, such as Stachybotrys (black mold), which can cause stachybotryotoxicosis. This is why, when dealing with substantial mold, you should always contact professionals and keep a backup plan. You should always advise your workers to cover their skin by wearing masks and gloves when cleaning mold out.
Legal Consequences
When it comes to mold exposure, as the owner of a restaurant, you might have to face some major legal risks. Especially if huge mold growth has taken over an entire walk-in cooler. Naturally, the first concern is failing your next health inspection. This can be disastrous for a growing restaurant, especially if you have to close until you pass the reinspection.
Your business could be held accountable if a customer becomes ill or successfully alleges that your items exposed them to mold toxins. However, the legal concerns do not end there. If a member of your staff becomes ill while cleaning up the mold, you may face a workers’ compensation issue. Even if there wasn’t a single dish cooked using mold-exempt ingredients, direct contact with mold poses a serious health risk.
Mold Prevention for Your Walk-in Cooler/Freezer
We have shown you the risks attached to mold growth. Below we have mentioned how you can prevent mold from developing on your walk-in coolers or freezers.
Keep the Unit Dry
Mold cannot reproduce and grow without moisture. Check that the cooling system is working properly, including the condensing coil, evaporator, and fans. Those systems will circulate the air and remove any excess moisture.
Any standing water should be removed because it can evaporate and leave unwanted dampness. Condensing coils, fans, and evaporators are the parts that need regular maintenance in order to work effectively.
Minimize Condensation Levels
As mentioned above, condensation occurs when there is more moisture in the air, resulting in a higher level of humidity. Humidity is the best home for mold growth. Make sure your walk-in cooler doesn’t have any standing water that could cause condensation to form.
Keep the Doors of your Walk-in Freezers or Coolers closed
Leaving doors open can cause your commercial refrigerator’s humidity level to fluctuate, making it more susceptible to mold growth. Outside air containing mold spores can also infiltrate your equipment, promoting mold growth. To avoid this, make sure your door is constantly shut tightly.
Clean up the Water Spills Immediately
By raising the total humidity of your refrigeration equipment, standing water can provide an ideal habitat for mold to grow. If there is any standing water, it should be cleaned up as soon as possible. It’s a good idea to inspect your refrigerated equipment on a regular basis to see if any water needs to be removed. Contact a professional in case you are worried about mold growth or standing water in your refrigeration equipment.
Keep it Cool Properly
Mold spores will not grow in your walk-in cooler if the temperature is kept between 36 and 45 degrees Fahrenheit. Temperature swings, on the other hand, can be problematic. That’s why it’s always a good idea to double-check that the door is properly closed and shut. This will not only keep the temperature stable but will also keep mold spores from entering the cooler.
How to Stop Mold Growth in your Commercial Property
You may come across a lot of incidents where businesses are being forced to shut down due to poisonous mold growth in their commercial property that has caused many workers to suffer from respiratory problems and many others. So, as a consequence, business comes to an end hence causing the company executives to face serious legal action. Because of these severe health ramifications to workers, it causes a negative impression on a company’s bottom line, it is very essential to execute a process that helps you prevent mold growth in commercial property.
You must be aware of the fact that mold counts are higher in humid conditions as compared to dry conditions and some kind of mold is even present indoors as well. There are many available commercial HVAC systems that can control climate and moisture in your property, which can easily prevent mold growth. You may note that some poorly maintained commercial HVAC systems can serve as both a laboratory for growing mold and a highway system for transporting mold spores in your whole property. But here the good news is that interior mold c is not impossible to control, and it can easily be controlled through regular commercial property maintenance and inspections that are usually combined with the proper design, installation, and maintenance of commercial HVAC systems.
Ways to control indoor mold
If you have a proper understanding of the spread of molds, you may see that how the weak property maintenance and badly maintained HVAC systems are contributing to mold growth in your commercial property. Mold is normally only considered as a problem when you can see it, but at that point when it is even visible to you, your commercial property’s air quality has already been affected. You can prevent mold growth in commercial facilities by understanding the condition that is causing the mold to spread.
The best possible way to avert the growth of the mold is to reduce moisture with regular property maintenance and inspection process. Here are some points that can help you control interior mold:
- You need to inspect all the areas of the property even if they are the smallest places you have to inspect them for moisture, mold, and water damage regularly. Mold is devious and sneaky it can get almost everywhere without you even realizing it.
- At first, try to repair any sort of leaks and water damages you find as soon as possible without wasting any further time.
- Clean HVAC system coils and drip pans frequently. Pans that are clogged and that are not draining properly causes moisture to build up, and it may become a breeding ground for mold.
- You need to make sure that all HVAC ducts and system elements such as air handlers, blowers, and any confined chambers are free of any moisture and not storing water in them.
- You have to perform proper housekeeping in all areas of the property keeping in mind that you let the walls and floors dry.
- Check the accurate location of HVAC air intakes.
- Air that is being pulled in from areas near standing water or dumpsters can cause a production in fungal spores inside the property.
If you already have a mold problem in your commercial area, just cleaning up the upper surface will not do any good to you. You need to call someone who is explicitly trained in the area of commercial mold removal to get rid of it completely and thoroughly. You may have to hire someone who is a commercial mold remediation specialist. Once the mold is eliminated completely, you may create an examination process that will incorporate a routine commercial HVAC maintenance plan to stop mold from producing in the future. You need to make sure that other than property maintenance, properly designed, installed, and maintained commercial HVAC systems can go a long way toward avoiding indoor mold problems at your commercial property.
Why You Should Keep Tabs on Your Commercial HVAC System
As stated earlier in this article, mold does not appear on its own without having a proper suitable environment for it to grow, mold generally grows under certain conditions. Mold always requires water, a source of food, and the right temperature for it to grow. Now you may wonder what do molds feed on? Well, your commercial property is full of the food that molds need in order to grow, starting from drywall and carpeting to paper, wood, and furnishings they feed on everything and anything that comes in contact. The water comes from the excess moisture caused by relative temperatures that promote mold production and in these elements, the HVAC system is involved throughout.
You must be aware of the fact that your HVAC system can easily cause and create a suitable environment for mols to grow in the indoor levels of your property. If your HVAC system is not properly designed or has any sort of functioning issues, it will not only produce moisture that will promote mold growth, but it will also give mold spores a handy mode of transportation throughout the property through their ducts. To save yourself from this problem, you have to make sure to pay proper attention to your heating and air conditioning system and take all possible measures that allow it to effectively control mold development.
Check the coils and drain pans properly
As we know that the coils dehumidify the air thus causing condensation and the water to drip into the drain pan. When water fails to drain well through the deep seal trap in the pan, though, it can build up and let the mold to grow making the perfect environment for them to grow. You have to make sure the drain pan is accurately cleaned and tilted to prevent this to happen.
Proper ventilation and dehumidification equipment
Getting proper ventilation and dehumidification equipment can help get rid of excess indoor moisture in your commercial property and it will also reduce the suitable environment for mold production. All-Weather Heating & Air Conditioning offers a wide range of ventilators and dehumidifiers from top manufacturers that can easily meet your needs.
Investing in regular HVAC inspections and tune-ups
Some of the parts of your HVAC system can become wet and create issues that may lead to mold production. These parts may include outdoor air dampers, ducts, and air filters. You will have to inspect these problems at an early stage and deal with them as soon as possible by turning to All Weather Heating & Air Conditioning for regular inspections and tune-ups.
How to prevent mold in the refrigerator?
There isn’t a lot you can do once you spot mold growing in the fridge but knowing how to prevent it in the future after it’s been cleaned will save you from ever having to do it again. In order to prevent mold growth in the refrigerator distilled white vinegar is a powerful killer and it is also a lot of us’ favorite options in order to clean the fridge. All you have to do is to take out all the shelves and drawers that are easily removable so that you may spray them down with this vinegar (do not dilute the vinegar). Then you will have to let the pieces sit for a few minutes while you spray the inside of the fridge. You can get every nook and cranny in case you want to be extra thorough. You can then scrub the surfaces with the help of a rag wipe again with a clean damp cloth, and then dry all the surfaces. Repeat this step as needed and try to make sure that you throw away any paper towels and wash away all the rags that have come into contact with the mold you will have to use hot water and detergent for this purpose. Along with that make sure to check the rubber seal around the door. If there is any mold, you can also remove it with 1 tablespoon of chlorine bleach mixed with 1 quart of water. In case you feel like you can also add a box of baking soda or lemon wedges for extra deodorizing measures.
Along with the vinegar trick, there is another popular traditional tip for you to maintain your refrigerator mold-free is you can place a cotton sock filled with baking soda in the compartments. Baking soda has got a neutralizing effect.
Can mold grow on food in the freezer?
Freezer burn and mold can also gather at the inside of your refrigerator or even the freezer if they are not cleaned in a proper way. Remember that ice can also formulate on the walls of the freezer if the temperature setting is extremely cold for an extended period. This can also harm any of the food that is inside the unit and can cause damage to the refrigerator itself.
There is some sort of bacteria and molds that would grow at certain temperatures. The specific bacteria that might cause the most food spoilage would occur at the medium range of 68-113 Fahrenheit range. These bacteria are known as mesophiles. They can have molds and bacteria that grow at even hotter temperatures or in any other case, colder (psychrophiles aka cold-lovers). Either that, or it is just a collection of unknown material that could be from packaging dye scrapings that are collected on the ice.
What causes black mold in refrigerators?
The steady moisture, loosely sealed leftovers, minimal air movement, and persistent darkness can make the inside of your fridge the perfect multiplying ground for black mold. Always remember that no matter what sort of mold it is, it would spread through the air and produce mold naturally and they can still be eaten after you cut off the mold. These sorts of molds are less likely to spread to other food products and surfaces.
Rotting foods, that include grains and nuts are more likely to develop mold growth that would not only destroy the food but is also dangerous to eat. These molds are more likely to spread in the refrigerator through the circulation of air, and by sitting in a drawer or on a shelf long enough for the spores to transfer to the plastic or metal surface. As the refrigerator is dark much of the day that allows mold to grow quickly, but nobody can actually see it until it has become a larger issue.
If the mold is being caused by something other than food rot or returns even after you have cleaned the fridge thoroughly, you may have a mechanical problem with your refrigerator. Possibly the humidity level is a lot higher, and the leak in the waterline may encourage the growth of the mold through any surface contact. Some specific types of food, such as cheese and hard salami would.
Is black mold in the freezer dangerous?
In case you find black mold or any other kind of mold in your refrigerator, you have to figure out the main cause and get rid of the mold immediately by taking proper steps to prevent the mold from coming back. Mold is usually spread through the air and through any surface contact. The topmost source of refrigerator mold is mold that is on the food. Some of the food products, such as cheese and hard salami would produce mold naturally and can still be eaten once the mold is cut away. These kinds of molds are less likely to spread to other foods and surfaces. Rotting foods, including most produce, grains, and nuts, will develop mold growth that not only destroys the food but also is extremely dangerous to consume.
How to prevent mold in the freezer?
While you are storing a refrigerator (fridge) one of the greatest worries is always the mold. If the entire fridge is not thoroughly cleaned and dried before you sort and store it correctly there is a risk it will be in such a state when removed from your storage unit, that it can no longer be used.
Here are four steps that may help you to make sure that your fridge is in working order while stored.
- Leave plenty of time for defrosting.
- Clean your fridge thoroughly.
- Keep it upright.
- Keep it dry.
How to clean mold from the freezer?
Every time you open your freezer always have a towel and bucket handy to clean any extra liquid. That only depends on the type of freezer that you own, your freezer must have any accumulated water inside the freezer. This is more likely in the case of a freezer that demands to have a manual defrost. Which would make it really important to make sure that your freezer is unplugged in case water spills or pools near the power source.
It is suggested that mixing equal parts of white vinegar and water in a spray bottle and sprays the inside of the freezer before you use a paper towel so that you can wipe away the mold. Always keep a trash bag or can close to you while you work so you can dispose of the paper towels right away to avoid creating an additional mess.
In case your freezer is extremely moldy, you can always spray the vinegar and water on the interior and let it sit for at least 20 minutes to give it time to take action on the mold and begin to dissolve it. A bristled brush or sponge can also be used that has a rough coating to remove tough mold. As you clean, be sure to thoroughly access all nooks and crannies of the freezer, as well as the rubber gasket around the door.
How long does it take for mold to grow in a fridge?
All kinds of mold can spread in as little as a few hours. In case a mold spore lands on a moist organic material, it would root into the porous surface and begins to feed off the organic substance. Within some hours, the harmful microorganisms would start spreading to adjacent moist areas, damaging the structural integrity of the material they are attached to. Once this mold gets a foothold on a surface at your home, it would quickly fill the air with thousands of spores that are spread throughout the building, affecting more and more areas with every passing hour. So, there is only one way for you to prevent mold from infesting your home following an incident of water damage is to dry the premises within the first 48 hours after the water intrusion.
Does freezing kill mold?
It should be noted that freezing does not kill mold. It suspends mold growth for as long as the material is frozen. Therefore, mold-affected papers would still need to be treated after freezing and vacuum freeze drying are completed.
