This is not merely alarmist. As several global news stories have shown us, there are cases of edible ice contamination happening all around the world, and more often than we thought.
In the US in 2013, an outbreak of norovirus caused by dirty ice at a golf course in Phoenix sickened 80 people. In 2018, a reporter who looked at restaurant report cards in North Carolina every week saw “dirty ice machines” often cited in the public reports.
Meanwhile, in China in 2013, ice cubes at fast-food chains were found to be riddled with 13 times more bacteria than toilet water. And in Hong Kong in 2017, edible ice samples collected under the routine Food Surveillance Programme of the Centre for Food Safety (CFS) were found to contain excessive coliform bacteria, organisms that are present in the environment and in the feces of all warm-blooded animals and humans.
You may think European countries probably apply striker regulations and prevention toward food safety. However, studies done in Europe have shown dirty ice cases as well. In 2017, an undercover study by the BBC investigated iced beverages in the U.K. and found that out of 30 samples taken from three different fast-food restaurants, more than half were contaminated with fecal coliform bacteria. In 2013, a newspaper did an experiment that collected ice from ten well-known fast-food chains and announced that in six out of ten locations, those ice cubes “contained higher levels of bacteria than the water samples taken from toilet bowls at the same establishments”.
Most people don’t give a second thought when they use ice. But those real-life cases above reveal the potential harms of dirty ice to our health and even to the public health system. It’s a little-known fact that ice machines that produce the ice we drink could potentially be a home for all manner of harmful bacteria, viruses, mold, and other microorganisms.
Ice should always be manufactured and handled with the same strict standards that we use to treat the rest of our food. Since more and more research has shown the importance of edible ice safety following numerous cases of edible ice contamination happening in the world, governments have made regulations for ice manufacturing and handling to make sure that edible ice must be produced, stored, and transported in clean and sanitary conditions. Ice manufacturers and food and beverage businesses such as restaurants, hotels, and bars, must monitor the cleanliness and hygiene of employees, use properly cleaned and maintained equipment, and use water that is safe and sanitary.
In addition to the above precautions, ozone is a powerful solution to help prevent bacteria from getting into ice that you or your customers consume.
Ozonated water, which is usually produced by electrolytic ozone generators (E.O.G), is one of the strongest disinfectants known to mankind. It is an effective and fast disinfectant. Compared to general chlorine-based disinfectants, ozone disinfection speed is 3,000 times faster and 50 times stronger. Ozone water is also one of the safest disinfectants. It’s 100 percent natural, which makes it perfectly safe for human beings as well as for the environment in the right amounts.
When it comes to ice and drinking water, the CDC has proclaimed that ozone is a safe and effective sanitation method, protecting against even some of the most resistant microorganisms.
Electrolytic ozone treatment works by combining electricity with water through an electrolytic ozone generator (E.O.G). It’s considered a safe and effective disinfectant alternative to chemicals for food safety applications. Including decontamination of water and sanitization of kitchen equipment, ozone is also very effective in eliminating biological matter in the water like bacteria or viruses, killing them instantly.
After filtration, the water goes through electrolysis and the chemical ionization is finished. This helps remove any particulate matter that was created in the process. The final water supply is then completely free of impurities.?

Ozonated Water vs UV Light Sanitation: Which is the Best Chemical-Free Sanitation?
Is Ozone Harmful to Humans?
Food Safety and Ozone: How Ozone is Becoming the Industry Standard?
Ozonated water is one of the most effective sanitation solutions on the market. Recent advancements in electrolytic ozone technology have made ozone even more accessible by allowing the generating of ozonated water at higher concentrations with smaller machines that can fit in compact spaces. Ozone technology is used across a variety of industries, with applications for healthcare, food safety and sanitation, beverage, dentistry, professional laundry, and professional cleaning.
For example, ozonated water can kill bacteria on surfaces of kitchen counters and food prep stations. It’s commonly used to disinfect fish, meat, vegetables, and poultry by removing bacteria and pathogens through a wash with ozonated water. It’s also effective at removing odors from mildew in washing machines and disinfecting dental water units.
Thanks to the ozone’s short half-life of an average of 15 minutes, it dissipates into oxygen after disinfection. This means if you were to disinfect a room with ozone mist, after twenty minutes there wouldn’t be any trace of ozone left, unlike chlorine. This is because ozone is unstable and reverts back to oxygen (O2). Research by the world recognized laboratory Campden BRI backs up these claims. Trials undertaken in 2014 found that ozone at the right concentrations and contact times can be an effective environmental disinfectant and when used correctly, causes no adverse effects after disinfection.
We might be familiar with ozone in our atmosphere. But ozone can be generated on-demand as well. Ozone is highly reactive and attracts electrons from other compounds. It oxidizes — a process where it undergoes a reaction in which electrons are lost — drastically reducing the biological integrity of anything it attacks. Ozone ruptures the cellular walls of bacteria causing the cells to break down and so there’s no chance for the biological organism to build up immunity, unlike chemical disinfectants. Ozone can oxidize certain minerals as well, removing manganese and iron out of drinking water.
Ozonated water has been a blessing for the food and beverage and healthcare industries. In central kitchens and restaurant food prep stations, bacteria collect on surfaces that are used to prepare food. Some hotel chains and large restaurants require multiple food prep stations to handle a large number of customers. This makes it a challenge for kitchen staff to use chlorine to disinfect these food prep surfaces every night. For one, the storage of enough chlorine to disinfect every food prep station on a daily basis uses valuable facility space. Secondly, mixing the chlorine disinfection solution is prone to human error, especially if employees do not undergo proper training. With ozone, kitchen staff can simply spray ozonated water via an ozone spray bottle on surfaces, and rid them of bacteria by simply wiping them down, saving time, money, and hassle.
Ozonated water made through electrolytic ozone generators is safe for humans. The US and Europe have strict indoor ozone safety standards. If exposure is controlled, there are no safety issues. However, ozonated gas generated through the corona discharge methods does bring safety concerns. When inhaled, ozone gas can damage lungs, and relatively low amounts can cause chest pain, coughing, shortness of breath, and throat irritation. Ozone may also have negative effects on people with respiratory conditions such as asthma and affect their ability to fight respiratory infections.
Compared to the long term effects of using chlorine for disinfection, ozone is safer. Chlorine is a chemical disinfection agent that has drawbacks for both humans and the environment. Long-term exposure to low levels of chlorine gas is potentially linked to lung disease, including bronchitis, shortness of breath, possibly permanent damage, as well as tooth corrosion. Chlorine is also a comparatively weaker disinfection agent, offering relatively low protection against protozoa. On top of this, chlorine has lower disinfection effectiveness in turbid water, leaves a bad taste and odor, and is subject to human error when mixing the solution. This can lead to dangerous outcomes and often leads to using unsafe amounts.
Ozone is not to be feared. There is a myriad of benefits from ozonated water technology. While there are guidelines to follow for the safe and proper use of ozone, the benefits of ozonated water and electrolytic ozone technology far outweigh these concerns. Business owners are realizing this and are starting to replace chemical disinfection processes with ozone water at record numbers, due to both the overwhelming effectiveness and its benefits for the environment.
BES Group is one of the leading ozonated water manufactures. With numerous patents for revolutionary electrolytic ozone technology, BES Group ozone generators produce higher concentrations of ozonated water through compact devices that can be installed almost anywhere. With recent reports that ozonated water can kill Covid-19, ozone is now making a comeback in helping keep people safe from infection. Ozonated water is particularly important in businesses that fall into high-risk categories for Covid-19 infection, such as nursing homes, hospitals, and bars. Click here to learn more.

]]>Those looking for a sanitation solution for their home kitchen might look to chemicals such as chlorine. However, there’s a better option that works more efficiently and without the chemical residue that chlorine leaves. Ozone and ozonated water is a sanitation technology that has been used to disinfect water for over a hundred years. It has been used predominantly in Europe and Asia, and thanks to developments in electrolytic ozone generation technology, it’s gaining greater appeal in the US and East Asia as a perfect sanitizing solution for home and central kitchens.
Ozonated water does not add any chemicals to the water (as with chlorination), meaning that the surfaces, the cooking utensils, and even the hands that come into contact with it do not have trace chemicals. With ozonated water, you can disinfect and sanitize leaving only safe and harmless oxygen as a byproduct.
Ozone is a reactive gas consisting of three oxygen atoms. The gas will readily degrade back to oxygen, and during this process, a free oxygen atom will form that will be highly reactive against bacteria and viruses. Compared to chlorination, ozone works faster and more effectively in sanitizing. In addition, ozone’s oxidizing properties work against concentrations of iron, manganese, and sulfur, and fight or eliminate unpleasant odors, making it effective in keeping kitchen odors from traveling to other parts of the home.
In the past, ozone generation sanitation systems used dated methods to generate ozone water. Ozone sanitation required expensive machinery and trained specialists to install them. Now, hygiene-minded homeowners can easily install a Waterline Sanitation System (WSS) to water lines in home kitchens. These devices, also referred to as electrolytic ozone generators, work by injecting ozone into the water tap water with the push of a button, which then kills bacteria, viruses, biofilm, and more dangerous particles within seconds.
Home cooks and professional chefs have a responsibility to do their part in keeping food clean and sanitary when dealing with food — and it starts with handwashing. Handwashing with ozonated water is a safe and effective way to prevent bacteria and viruses from ending up in our food. 75% alcohol sprays are the standard, but they leave a pungent odor in the air, and inhaling alcohol can be harmful to us over time. Instead of using 75% alcohol spray after washing your hands, you can use ozonated water. It brings the same result without the harsh chemicals. With COVID-19 a major health threat for the foreseeable future, homeowners can integrate ozone water systems for handwashing in their home kitchens and keep themselves and their loved ones safe.
Although ozonated water has numerous advantages over chemical cleaning methods like chlorine, some homeowners may prefer to use ozone spray to spray and wipe down potentially contaminated surfaces. Ozone spray bottles, like the Biolux handheld Mobile Ozone Spray (MOS) are a new, handheld solution. It’s a simple, rechargeable bottle that uses an advanced electrolytic oxidation process to convert tap water into dissolved ozonated water making for an instant, chemical-free sanitizer. The MOS allows you to effortlessly spray down and instantly sanitize any utensil, countertop, table, or surface. As with all ozonation processes, it’s effective, safe, and environmentally friendly, and quickly and thoroughly kills bacteria, viruses, and disease-causing microorganisms (organic and inorganic). It also kills pathogens in foods that can lead to illnesses, including Salmonella, Shigella, Campylobacter, and E. coli.
The BES’s Mobile Ozone Sprayer (MOS) can be used to disinfect produce, cooking utensils, cutting boards, and other tools and surfaces that come in contact with food. The MOS is easy to use. Once the sprayer is charged, fill it with tap water and it’s ready. Push the ozone generator button on the bottle and quick, easy, and instant sanitation for your kitchen is in the palm of your hand. It’s safe for rinsing food as ozonated water does not leave any chemical residue. The MOS is safe for children to use and does not irritate the skin upon contact. It’s also great for deodorizing appliances and waste-causing smells; the odors that emanate from trash cans and kitchen garbage disposals.
While chlorine and chemical sanitation methods have been used in the past, the threat of COVID-19 entering our homes means taking extra precautions. Using chemicals on a daily basis causes harm to you and your family over time. Thus, ozonated water technologies are a more healthy and environmental option.
As the kitchen is the focal point of your home. Care and cleanliness are essential. With BES’s full suite of electrolytic powered technology home care products, you can cover all your sanitizing needs to keep your kitchen, and your family, safe, healthy, and happy.

]]>In September 2006, E. coli-contaminated spinach caused 204 people to fall ill nationally, leaving 102 people hospitalized and causing three deaths. The investigation that followed showed the spinach had been grown, packed, processed, and bagged in the Salinas Valley, California. It was one of the most high-profile food borne illness outbreaks in US history. This incident was a reckoning on how food producers keep consumers safe.
While these numbers are minuscule compared to the current COVID-19 outbreak, the illnesses, deaths, and suffering could have been prevented with proper sanitation methods in place.
In a new post COVID world, consumers are once again on high alert about how their food is being prepared. Experts say it’s possible the new coronavirus might linger on fruits and vegetables that have been handled by a person with the virus. Once again, food sanitation and the processes both the food and beverage industry and supermarkets are using to ensure food is clean and safe are once again being scrutinized under the public eye.
By law, every grocery store, restaurant, bar, and all other commercial food suppliers are obligated to disinfect food sources from harmful bacteria, viruses, and a host of parasitic microbes before they sell to consumers. Ozonated water is proving to be one of the best technologies available to do just this and is gradually replacing older sanitation methods for many sanitation applications.
Chemicals such as chlorine have been traditionally used to sanitize food, but ozonation is proving to be a safer, cleaner technology. Ozonation is the generation of ozone that can be injected into water or air to destroy harmful bacteria and impurities, when it’s injected to treat water it produces ozonated water.
Ozone water is changing the way we sanitize food. Let’s take a look at five reasons why.
For these reasons and more ozone is becoming an invaluable part of many aspects of food processing and food safety including:
Ozone can be used at every step of food production to help eliminate the potential for harmful contamination. Ozone is in our lives, whether we realize it not. It’s become one of our main allies in preventing food-borne illness and bacterial infections.
Ozonation treatments and processes are constantly developing but there are still some causes for consent that have prevented some members of the food and beverage industry from doing away with their chlorine vats.
Low dosages of ozone may not effectively inactivate some viruses, spores, and cysts. Ozonation is, by nature, more complex than other disinfection technologies. Also, the initial cost of treatment is relatively high compared to chlorine.
In a post-COVID-19, consumers are rightfully concerned about how their food is processed and sanitized. But we can no longer afford to take chances with how we sanitize our food using traditional methods like chlorine. Businesses and the general population both stand to benefit from adopting the most technologically advanced food sanitization methods.
Ozone is on the cusp of becoming a mainstream method for sanitation, it can be another tool in our arsenal to help prevent another Salinas Valley-type disaster through proper sanitation of the food we eat and the beverages we drink.

]]>How Ozone Helps Dentists Keep Patients Safe from Contaminated Water最先出現在百特集團 | 中文官方網站。
]]>A big problem for dentists is keeping water that flows from dental unit waterlines safe from biofilm that contaminates water flowing through these units. Dental unit waterlines are plastic tubing that carries water to a dentist’s high-speed handpiece, air/water syringe, and ultrasonic scaler. Patients ingest water from these tubes and dental staff are exposed to aerosols on a daily basis.
Biofilm is a thin, slimy film of bacteria that sticks to moist surfaces, such as those inside dental unit waterlines. Biofilm develops in dental unit waterlines because of the long, narrow tubing and periods of slow or stopped-flow rates used in dental clinics, and the potential for retraction of oral fluids by patients. As a result, common water bacteria can be found in alarmingly high numbers of untreated dental unit water systems.
Biofilm is not eliminated by flushing the water lines with tap water, a daily procedure recommended by the CDC to ensure clean water in dental offices. Some of these microorganisms found in untreated dental unit water cause diseases, including Legionella, Pseudomonas aeruginosa, and nontuberculous Mycobacterium.
Not only patients but dental health care personnel are also placed at risk of adverse health effects if water is not appropriately treated. Previously, dentists used a combination of chemicals and multi-step procedures to disinfect water lines. But in recent years, the industry has adopted ozone as a safer and more efficient disinfection method, not to mention more cost-effective.
Ozone (O3) is an active gas consisting of three atoms of oxygen. It is active because the gas will readily degrade back to its stable state, diatomic oxygen (O2) with the formation of free oxygen atoms or free radicals. The free oxygen atoms or radicals are highly reactive and they will oxidize almost anything it contacts (including viruses, bacteria, organic and inorganic compounds), making ozone an enormously powerful disinfectant and oxidizer.
Ozone is a very good alternative and additional support to standard disinfectants due to its acknowledged disinfection power. Ozone water can directly oxidize and decompose essential biomolecular components in bacteria. All vital functions of bacteria (incapable of developing any self-immunity) are stopped as a result of applying ozone for just a few seconds and can disinfect dental unit water lines in seconds.
In a 2015 Egypt study by Iran J Parasitol, two dental unit waterlines were tested for presence of Acanthamoeba microbes — harmful bacteria that is prone to develop in these narrow plastic tubes. When testing untreated water lines, the research team discovered bacteria in 100 percent of dental unit waterlines, compared to just 72 percent of tap water samples. That means tap water is cleaner than untreated dental unit waterlines.
In the study, aqueous ozone was injected into the dental unit water bottles for five minutes in the first unit and for ten minutes in a second unit. The lines were then flushed with ozonated water for five minutes, after which water was immediately sampled via the high-speed handpiece into sterile containers. This was repeated daily every morning for seven days. Water samples were collected before and after treatment. All the samples were cultured on nutrient agar plates and incubated at 37 °C for 7 days to determine the presence of Acanthamoeba bacteria before and after exposure to ozone.
Researchers discovered that when Acanthamoeba bacteria was exposed to several concentrations of ozonated water, the cell viability of the bacteria decreased to 52 percent after exposure to ozonated water for just four minutes, while Acanthamoeba was killed (100 percent) after just five minutes of exposure. This is why dentists have adopted aqueous ozone systems in their practices.
The results show just how effective ozonated water is for keeping these bacteria from infecting patients undergoing dental procedures, making it an invaluable tool for dentists in keeping patients and dental staff safe. At the same time, patients undergoing stressful dental procedures will have peace of mind knowing they won’t be exposed to contaminated water.
Since 1988, BES Group has been a leading electrolytic ozone manufacturer dedicated to “chemical-free” sanitation solutions. BioSure Professional, under BES Group, provides professional solutions applying advanced ozone technologies in healthcare, food safety and hygiene, commercial laundry, air quality control, water treatment, and other industries.

]]>Contamination in ice could be more common than we thought. In July 2017, an edible ice sample collected under the routine Food Surveillance Programme of the Centre for Food Safety (CFS) was found to contain excessive coliform bacteria. In the UK, a news article was published that collected ice from ten well-known fast-food chains and announced that in six out of ten locations, those ice cubes “contained higher levels of bacteria than the water samples taken from toilet bowls at the same establishments”.
The Important of Edible Ice Safety
Ice should always be manufactured and handled with the same strict standards that we use to treat our food. Ever since the Journal of the American Medical Association (JAMA) ran an article on the food safety of the ice, the focus on the safety of commercial ice has been closely inspected. Following safe food handling guidelines is critical in preventing the spread of foodborne illness and the same should be applied to consumer ice production.
Ice machines should be cleaned regularly and thoroughly, with ice storage bins emptied and cleaned on a weekly or biweekly basis to cut the risk of possible contamination. This is a critically important, albeit time consuming task. Ice machines should be cleaned and descaled at least once every six months. And employees who handle ice or utensils that touch ice should go through proper training before they start handling ice that customers consume.
We can never be too cautious when it comes to food safety. In addition to the above precautions, ozone is a powerful solution to help prevent bacteria from getting into ice that you or your customers consume.
The Magic of Ozone
Ozone is one of the most effective solutions for protecting commercial ice machines. By injecting aqueous ozone into the ice machine’s incoming water line, we are able to protect more parts of the machine from pathogen build-up. As the ozonated water flows through the pipes, tubes, and different mechanisms of the ice machine, it continues to kill bacteria it comes in contact with. This protection continues through the entire machine and is frozen into the ice itself where it will safely off-gas which helps to protect the ice storage bin walls as well. Through this way, cleaner, safe ice is produced, while lowering overall maintenance on the ice machine.
How it works
Electrolytic ozone treatment works by combining electricity with water through an electrolytic ozone generator(EOG). It’s considered a safe and effective disinfectant alternative to chemicals for food safety applications. Including decontamination of water and sterilization of kitchen equipment, ozone is also very effective in eliminating biological matter in the water like bacteria or viruses, killing them instantly.
After filtration, the water goes through electrolysis and the chemical ionization is finished. This helps remove any particulate matter that was created in the process. The final water supply is then completely free of impurities.
When it comes to ice and drinking water, ozone is a safe and effective sanitation method, protecting against even some of the most resistant microorganisms, according to the CDC. In addition to its strong ability in disinfection, it leaves no chemical residues, and it has no taste or smell after reaction. It also has no effect on the pH balance of water. And rest assured, it causes no negative effect or irritation to our mouth, nose or skin, which makes it the perfect source of edible ice.
Ozone Ice Machine Disinfection Systems
Ozonated water is easy to obtain now with the availability of commercial ozone generators (link to product). The Ice Machine Disinfection System by BioSure uses patented electrolytic technology to generate ozone-dissolved water with adjustable ozonation levels. In other applications it can also be integrated with the existing water supply, transforming the general tap water into high-concentration antibacterial disinfection water.
The system utilizes BioSure patented technology to produce ozone, the strongest food grade disinfectant approved by the FDA. When integrated with an ice machine under clean and extra clean settings, the ice harvest is disinfected and free of microorganisms. Anti-bacterial ice means it has residual disinfection properties to further inhibit microbial growth.
The ice that is made from this ozone-treated water is perfect for consumption and use in high quality products, as well as for storage of food products to maintain high levels of hygiene and prolong freshness. Moreover, the ozonated water will eliminate and prevent biofilm growth in the waterline as well as its surroundings. When integrated with ice machines, ozonated water eliminates mold and microbial growth, minimizing maintenance on the machine and storage bins.
Additional Benefits
Ozone ice also reduces costs associated with cleaning crews that use chemical solutions to keep commercial ice machines sanitized. Then there are the costs and risks of cleaning crews damaging ice machines from regularly cleaning them by hand. Ozone eliminates these risks and costs in one fell swoop.
The ice and water produced with ozone will completely sanitize and improve the quality of beverages. Also, the attached spray hose allows for convenient ice storage bin disinfection. The system will effectively improve any ice produced through better safety, without altering the taste and smell.
BES patented technology only uses tap water to create a high purity ozonated. This presents considerable benefits compared to traditional methods of ozone production by air water. These advantages include ozonated water that achieves a concentration above 28 weight percent (wt%). It’s also safe to use and free of harmful nitrogen oxides (NoX). It’s unaffected by humidity, and the technology produces a consistent and reliable ozonated water concentration compared to traditional methods of ozonation
Aside from just ice machines, ozone is used in a number of applications and industries, including medical, dental, and food sanitation industries among others. It prevents decay and eliminates decomposition agents such as bacteria, yeast, and molds, and enhances food safety by reducing populations of foodborne pathogens, including E. coli, Salmonella, Listeria, and Shigella.
When considering the alternative, ozone is invaluable to businesses that serve cold beverages, whether it’s cafes, restaurants, or bars. These establishments have a responsibility to keep their customers safe. With ozone, both business owners and customers have peace of mind when enjoying a cold drink on a hot summer day.
