Safety in food preparation is important, particularly in a commercial setting, where food contamination can result in waste of money, loss of reputation, loss of income, loss of business and, most importantly, potential harm to people who consume contaminated food. Optimizing food safety, then, is a priority and the best way to optimize food safety is through the use of UV light.

Temperature-Resistant Pathogens Are A Risk To Food Safety

Refrigeration has long been relied on to mitigate the growth of pathogenic bacteria in food. However, it’s crucial to know some bacterial strains are resilient, even at low temperatures, and pose a risk to food safety.

Storing foods at 5°C has long been believed to curb the growth of food-borne pathogens. However, researchers discovered the emergence of a group of pathogens that undergo robust growth, even when stored at this temperature.

Ultraviolet (UV) technology provides chemical-free sanitization systems for homes or businesses that address the spread of disease-causing microorganisms at every stage of the food supply chain – especially in situations where other systems have limitations.

Harmful Microorganisms Can Multiply Undetected

When provided with the right conditions—nutrients, moisture, and favorable temperatures—pathogenic bacteria can undergo exponential growth; potentially doubling in number in as little as 20 minutes. Undetected by taste, smell, or appearance, these dangerous microorganisms render food unsuitable, and even hazardous for human consumption.

How UV Light Protects Against Harmful Microorganisms

Different wavelengths of UV light disrupt the DNA or RNA of microorganisms, preventing them from reproducing and causing harm. (See Principles Of Infection Control And The Role UV Light Plays [link to article] ) UV light combats a wide spectrum of pathogens, highlighting its potential as a comprehensive non-chemical sanitization solution for food safety.

UV Germicidal Lamps For Food Sanitization

UV germicidal disinfection works like a physical barrier against microorganisms. The short wavelengths of UV light, especially around 254 nanometers, are extremely effective in reducing spoilage and keeping food safe to consume.

This kind of UV light can eliminate up to 99.99% of harmful bacteria, viruses, moulds, fungi, and spores that are often found both on surfaces and in the air.

The food industry has utilized UVC technology for over 70 years due to its significant advantage over other microbial reduction systems, as it doesn’t change the flavour or colour of the food.

UV Sanitization Solutions In A Variety Of Settings

Early contamination intervention reduces the likelihood of widespread outbreaks. UV sanitization systems offer a chemical-free and diverse range of applications that can be used at every stage of the food supply chain.

Coolroom Fixtures – Installed in cold storage areas to disinfect surfaces and the air, preventing the growth and spread of bacteria and other microorganisms that could lead to food spoilage.

Water Treatment Units – Units equipped with UV technology disinfect water, eliminating harmful microorganisms.

Conveyor Belts – UV systems integrated into conveyor belts provide a continuous disinfection process of surfaces that are in contact with food products.

Cooking Hoods – UV UV technology can be applied inside cooking hoods to disinfect the air, preventing the spread of airborne microorganisms that may pose a risk to food safety.

Air-Conditioner Units – UV lamps installed in air conditioner units help maintain clean and sanitized air circulation, contributing to a healthier environment and reducing the risk of airborne contamination.

Portable Air Purifiers – UV technology purifies air in specific areas, offering a flexible and portable solution for maintaining clean air quality.

Bug Zappers and Trappers – UV light in bug zappers attracts and eliminates flying insects, preventing them from coming into contact with food products and reducing the risk of contamination.

Ozone Applications – UV technology generates ozone, which is a powerful disinfectant. Ozone applications are employed in various stages of food processing to sanitize surfaces and equipment and remove unpleasant odors.

Air Irradiation – UV light is used for air irradiation to disinfect the air in enclosed spaces, reducing the concentration of airborne pathogens that could potentially contaminate food products.
