UV Sterilization for Commercial Kitchens


Restaurants have a responsibility to their patrons to serve healthy food, free from foodborne diseases that have the potential to cause illness.  According to the Centers for Disease Control and Prevention (CDC), nearly 127,000 people are hospitalized every year with an illness caused by contaminated food and nearly 3,037 people die each year from a foodborne illness.  Ultraviolet (UV) light sterilization systems provide a solution to help restaurants provide safe and healthy food.

UV sterilization systems also help a restaurant maintain a cleaner facility to comply with food safety regulations and health department inspections.  UV air purification systems also help any facility to maintain a healthier eating area by disinfecting the air in public spaces.  UV air sterilization systems are proven to remove harmful airborne pathogens to reduce the risk of contracting an airborne illness. 

Food Irradiation with UV Germicidal Lamps

Food irradiation is the term used to describe UV germicidal lamps used to preserve food with ultraviolet radiation.  Food irradiation is proven to prevent infection from bacteria and preserve food without any adverse health risks.  UV light is proven to prevent foodborne illnesses such as E. Coli and Salmonella and also preserves food by preventing early sprouting of potatoes or culmination of foodborne insects. 

Restaurants can protect their food by using UV lights above food preparation areas and countertops as well as over food buffets or serving areas. UV radiation emitted at the optimal wavelength, 254 nanometer (nm), alters the DNA of harmful pathogens including bacteria and viruses, and is effective in food irradiation and also on surface sterilization applications. 

UV Air Sterilization

UV lamps are incorporated in HVAC systems to prevent the growth of mold and mildew on cooling coils and may also be aimed to reduce airborne pathogens circulating through the ventilation system.  UV air purification systems may also incorporate ozone lamps to remove foul odor from the air.  UV kitchen exhaust systems over commercial kitchen hoods can even prevent the build up of grease by oxidizing oil fumes into carbon dioxide and water molecules to be removed by kitchen exhaust. 

UV sterilization systems in commercial kitchens provide many benefits such as:  

  • Eliminates a fire hazard when used in kitchen exhaust systems by removing the threat of grease build up in the pipeline
  • Improves the safety of food with food irradiation
  • Eliminates bacteria and viruses on surfaces such as countertops 
  • Maintains a cleaner food storage and preparation area
  • Prevents mold and mildew in moist spaces such as a walk-in freezer
  • UV air sterilization improves the comfort and safety of indoor diners 

UVC germicidal lamps provide these benefits and more with a low-maintenance, highly effective sterilization system.  UV sterilization systems provide solutions to restaurants and commercial kitchens with safe and effective air and surface disinfection.

UV Germicidal Disinfection Helps Restaurants Stay Safe

Restaurants have a responsibility to provide a safe, clean environment to customers as well as to serve healthy food, free from harmful bacteria and pathogens. Foodborne illnesses cause an estimated 1,686 deaths every year in the U.S. with over 38 million reported cases of gastrointestinal illnesses. UVC lamps provide valuable benefits to all food establishments including restaurants, food and beverage processing facilities. 

UV disinfection of food products is called food irradiation and helps to prevent early spoilage and harmful bacteria and viruses from developing. Food irradiation is proven to eliminate Salmonella, E. Coli and other harmful microorganisms. UV sterilization lamps used on food products is regulated by the FDA as an approved disinfection method for use on many food items including:

  • Fruits and vegetables
  • Meats and raw poultry
  • Many dairy products
  • Beverages

UV Lamps Beneficial in Many Areas of Restaurants

In addition to improving the safety of food items, UV germicidal lamps can also be used to disinfect and sterilize surfaces such as all contact surfaces in restaurants like food preparation countertops and serving stations. UV lamps can be used in refrigerators and walk-in freezers to prevent mold and mildew which can occur in damp spaces. 

You might see UV lights over a food buffet, a deli, or over fruits and vegetables to prevent foodborne illnesses. UV disinfection in restaurants adds a layer of protection over regular cleaning methods and helps to keep patrons and staff safe from foodborne illnesses and contaminated surfaces. 

UV disinfection of surfaces in restaurants provides many benefits such as:

  • Prevents mildew and mold from developing in areas that generate moisture such as refrigerators and freezers
  • Sanitizes surfaces that come into contact with food items

Indoor Air Protection with UV Sterilization Lamps

Indoor air quality (IAQ) is an important consideration related to the comfort and health of building occupants. IAQ is affected by the quality of air in and around buildings with airborne contaminants existing both inside and outside. Controlling pollutants inside will help to reduce risk and improve the quality of indoor air for greater health and well-being. 

Airborne contaminants that exist both inside and outside of buildings include:
  • Indoor pollutants:
    • Wood burning stoves
    • Tobacco smoke
    • Cooking
    • Ozone and chemical emissions from cleaning solvents, electronic equipment and human metabolic byproducts

  • Outdoor pollutants:
    • Agricultural and farming
    • Vehicle exhaust
    • Waste management facilities
    • Chemical storage areas
    • Processing equipment emissions
    • Combustion byproducts during manufacturing

UV Air Purifier in HVAC Systems

HVAC systems can be a great source of air pollution if dirt accumulates in the ventilation system. Dirt combined with moisture and poor management of condensation can create serious air quality problems due to biological growth. This typically occurs due to problems with the cooling coil condensation, humidifiers and other sources of moisture, poor maintenance of filters and inadequate particle filtration.

Air contaminants may be either biological, gaseous or particulate. Methods of improving air quality include eliminating the source of emissions, capturing emissions at the source with exhaust, dilution, increased ventilation, filtration and air sterilization. Of these methods, the only one that actually eliminates biological contaminants is air sterilization. HEPA filters effectively filter particles as small as .3 microns, although they are ineffective against volatile organic compounds (VOCs) present on a molecular scale.

UV air sterilization is proven to eliminate VOCs and microorganisms such as bacteria, viruses, mold and fungal spores and many other air contaminants. In-duct UV air purification systems installed near the cooling coils of HVAC units prevent microbial growth on cooling coils, thus preventing the spread of these contaminants throughout the home, office or building.

Reduce Airborne Infections in Hospitals with UV HVAC Systems

Hospital stays may create additional illnesses for people already seeking treatment for health conditions.  The Center for Disease Control (CDC) estimates that nearly 1 in 25 patients acquire an additional infection contracted from a hospital stay.  These healthcare acquired infections (HAIs) pose a real threat to those with vulnerable health conditions and may literally be a matter of life or death.  It is estimated that nearly 100,000 people die each year in the U.S. due to an HAI.

Stagnant air in healthcare facilities and hospitals create a breeding ground for viruses and bacteria to reproduce.  Harmful airborne pathogens can quickly become a source of infection to patients and hospital staff.  Hospitals can drastically reduce the risk of airborne infections with a UVC germicidal HVAC system.  By installing UVC sterilization lamps in air flow systems these harmful microorganisms are instantly eliminated before they have a chance to infect patients and staff.

How Do UVC Germicidal HVAC Systems Work? 

UV light emitted in the UVC wavelength, specifically at 254 nm or 185 nm for ozone production effectively eliminates harmful pathogens as they pass through the UV air sterilization system.  UVC radiation quickly penetrates the cells of these infectious airborne microbes to render them non-viable and unable to reproduce.  UVC germicidal lamps are proven highly effective on even the most stubborn, drug resistance pathogens such as MRSA, strep, hepatitis, tuberculosis, vancomycin-resistant enterococci (VRE), C. difficile and many other infectious microorganisms.
