There are applications that include using UV light on actual consumables, as laid out in a paper published in Ozone Science and Engineering, also by Tatiana Koutchma: “Its applications include pasteurization of juices, post lethality treatment for meat, treatment of food contact surfaces and to extend the shelf-life of fresh produce.” In a paper from the National Center for Food Safety and Technology, Tatiana Koutchma says “applications include decontamination of surfaces of equipment in bakeries, cheese and meat plants…and for decontamination of conveyor surfaces and packaging containers.” John Velasco / Digital TrendsĪgain, this application uses significantly more powerful UV light than what is emitted by consumer-grade wands.
UV light sees most of its use in sanitizing surfaces in processing facilities. UV light is used in the food industry for disinfecting purposes, but not for food itself. UVC light is most effective when cleaning flat surfaces, as well. Without getting too scientific, the shorter wavelength makes it less effective at penetrating surfaces. UVC light is also only effective at surface-level cleaning.

A 2014 study in the American Journal of Infection Control found that portable UVC wands killed most commonly-found bacteria after 5 seconds of exposure, and were able to eliminate 90% of harder to kill bacteria after 40 seconds. Many people use the UVC wand as a sort of “flash” cleaning, but UVC light requires prolonged exposure to be truly effective.

It has a wavelength between 200 and 280 nanometers, but its ability to destroy bacteria and viruses is also what gives it the ability to cause skin cancer. UVC is the type of UV light used to clean and disinfect surfaces. UVC rays are the most energetic type of UV light and usually do not reach the ground. While all types of UV light can cause skin damage and skin cancer, according to the American Cancer Society, UVB rays are thought to cause most skin cancers. UVA and UVB are the most common types of UV produced by the sun, with longer wavelengths than UVC. There are three main types of UV light: UVA, UVB, and UVC. sergeyryzhov/Getty Images UV light takes time to clean While you probably shouldn’t eat food that you dropped on the floor to begin with, what if it’s from a particularly good meal? Or what if it’s food from a restaurant, and you want to be extra-safe concerning COVID-19? Can UV light help then? In short, the more moist a type of food - and the less frequently cleaned the floor - the more likely it is that dropped food is contaminated. Researchers from Rutgers University found that in some situations, bacterial transfer can happen instantaneously. There are multiple variables that come into play, including the moisture level of the food and the floor, the type of surface, and much more. He told Business Insider, “Obviously, food covered in visible dirt shouldn’t be eaten, but as long as it’s not obviously contaminated, the science shows that food is unlikely to have picked up harmful bacteria from a few seconds spent on an indoor floor.” John Velasco / Digital Trends In 2017, Anthony Hilton, a professor at Aston University, spoke out in favor of the 5-second rule. Ultimately, the 5-second rule is indeed myth - for the most part. If you really think about it, though, it doesn’t make sense. Microorganisms won’t take hold that fast. If you drop a piece of food on the ground, as long as you snatch it up within 5 seconds, it’s safe to eat. Most everyone knows of the 5-second rule.
