The Risks of Airborne Microbe Transmission in Restaurants
Air filtration is an important component to a healthy indoor environment for essential businesses and any indoor space where workers are present. Air filters and air purifiers have become a crucial addition to these commercial indoor spaces to help in the filtration process of airborne pollutants, particulate matter, and pathogens like viruses, bacteria, and mold spores. Many pathogens can be spread through aerosolized droplets in the air and this can lead to risks of transmission in the indoor space.
In this article we are going to learn more about the risks of transmission of airborne microbes in restaurants, understand how pathogens are spread in this commercial space, and how an air purifier will help in a restaurant to prevent microbes spreading in this air space.
Why hygiene is important in restaurants
Additionally, the indoor environment of the restaurant is another important aspect to a hygienic business. Cleaning the surfaces of this business with disinfectants and other cleaners to help eradicate pathogen growth – such as flooring, countertops, trays, etc. The process of using disinfectant cleaners will help to maintain a clean environment, and these actions should be taken several times throughout the day when preparing food and serving Customers. The most common form of pathogen spreading in a restaurant can include foodborne and airborne transmission – and therefore both of these fronts must be carefully considered and protected against within this essential business.
How do foodborne and airborne pathogens spread
Whereas, foodborne illnesses are caused by a variety of foodborne pathogenic bacteria, viruses, and parasites that will contaminate the food. These various types of foodborne illnesses will lead to food poisoning and other foodborne illness that are the result of the consumption of tainted food. This transmission method can also be a risk in restaurants, especially when surfaces are not cleaned properly, or food is not cooked appropriately to the right temperatures.
Commercial air filters for pathogen mitigation
Additionally, Ultraviolet light (UV light) is a known method for the inactivation or reduction in viability of pathogens, according to the CDC’s Infection Control Guidelines. However, the correct wavelength and control measures must be considered to avoid damage to the skin and eyes, as many UV light wavelengths can produce dangerous wavelengths that will ultimately produce ozone – a dangerous byproduct – within the indoor air space, reported by the American Cancer Society. Many air purification devices contain these UV lights to enable the capability to deactivate these airborne pathogens within the air purification system, but unfortunately a vast majority of these UV lights used in air purifiers fall within these hazardous wavelength production ranges which allow for the creation of ozone byproducts in the air.
Restaurant air purifier
This means that even though the UV lamp is relatively low intensity, given the airflow of the unit (approximately 80-250 cfm), the UV-C dosage required for destruction is created for the trapped pathogen because it will continue to be exposed to the UV-C radiation regardless of how quickly air is passing through the unit. Therefore, this air purification device will not only help to eradicate those worrisome pathogens that may be present and spreading in an indoor business like a restaurant, but it will also be used effectively and safely without any harm to occupants or workers. This simply placed air purification device may be just what a restaurant needs to provide air filtration, mitigation of pollutants, and general comfort to both employees and Customers visiting their business.
