Stethoscope Disinfection

Next week, we will be in New Orleans attending the AORN Expo 2018! We hope to see everyone there and work together to prevent infections within the healthcare industry. 

As mentioned in the Fall 2017 issue of Healthcare Environmental Solutions News, stethoscope cleaning has a compliance rate near 0%. Frightening! More specifically, after a one second long use, contamination rates equalize to that of the physician's hand. With HAI's of utmost concern, every source of possible infection must be addressed. Stethoscopes have been known to host potentially pathogenic organisms including, but not limited to, Staphylococcus aureus, Pseudomonas aeruginosa, Vancomycin-resistant Enterococcus, and Clostridium difficile (C. diff).

A solution that is quick and easy is the Flashbox-mini, a tabletop UV-C chamber disinfecting at a 99% kill rate of harmful organisms in mere minutes. UV-C provides a dry, chemical-free, and residue-free method of disinfection effective against bacteria, viruses, fungi, and spores. When micro-organisms are exposed to UV-C, the nuclei of the cells alter due to photolytic processes, preventing further replication, and causing cell death. The Flashbox-mini is a simple resolution to the complexity of HAI's and patient well-being.

Best Method to Disinfect Phones as Rated by MIT

Cell phones are in everyone’s hands, all day long. Our hands come in contact with many not so pleasant things, with harmful germs and organisms being of particular concern.  To try to mitigate any risks, MIT decided to determine how best to actually clean cell phones.  Researchers tested wipes, sprays, and ultraviolet light disinfection systems, namely the Flashbox-mini and PhoneSoap.  After various studies, they crowned the most effective to be ClorDiSys' Flashbox-mini.  We are proud to hold the title and thrilled that our company's device is able to provide a fast, easy, and chemical free method to disinfect our much-used and much-loved phones. Click here to read the full article!

Ultraviolet light disinfection works by utilizing the UV-C spectrum; the killing range of the ultraviolet spectrum.  When light is emitted onto the surface, the DNA of bacteria, viruses, and spores is altered to prevent replication and causes cell death. To use the Flashbox-mini, simply place a phone, or any other item, onto the high-quality quartz glass shelf, close the door, turn on the timer, and watch the glow.  After just 1 minute, 99% or higher of harmful organisms will be gone.

The role of humidity in decontamination

Elevating the relative humidity within the environment being decontaminated has been shown to be important when targeting sporicidal reduction.  Spores are hard-shelled, and the elevated humidity levels cause the spore walls to swell and crack.  This allows the sterilant to penetrate the spore wall much quicker and easier, providing faster kill times for the decontamination process.

This has been demonstrated through the use of chlorine dioxide gas.  Biological Indicators, consisting of over a million geobacillus stearothermophilus spores, were subjected to chlorine dioxide gas cycles at varying relative humidity levels and exposure dosages. Results are shown below, with greater dosages required at dryer conditions.

Disinfecting Ambulances with UV Light

Ambulances are one of the most crucial places to consider when trying to minimize the risk of Hospital Acquired Infections.  EMS vehicles are a hotbed for many different dangerous organisms to thrive given this constant interaction with the sick and wounded.  In fact, a study of Chicago area ambulances showed that 69% were infected with staphylococcus aureus in 2012.*  That is why there is a strong need to address the cleaning procedures within EMS vehicles.  Due to the short amount of downtime between deployments, rapid disinfection methods are needed.  Spraying and wiping chemicals can be time consuming, not effective, and dangerous to those exposed.  Fumigation may be effective, but is traditionally too lengthy of a process.  Ultraviolet Light disinfection fits the application nicely in that it does not require any chemicals to be used, is affordable to run, and only takes minutes for disinfection to occur.  Specifically designed for EMS vehicles, the Lantern is an easily portable device that can be placed on any surface and disinfect the vehicle of harmful bacteria within a minute and spores with 5 minutes.  To accommodate the design of EMS vehicles, the Lantern can also be turned upside down and hung from handrails.  The simplicity and ease of use, coupled with the rapid disinfection time allows for the Lantern to be used in between emergency activity, providing better safety for EMS crews, patients, and their families.

One of the biggest benefits of chlorine dioxide gas is how small it is!

In order to completely decontaminate a space, the method/chemical used must be able to reach and contact all organisms and pathogens with the area.  One disadvantage decontamination methods can have difficulty with are crevices and other niches.  These scratches, gaps, screw threads, and other hard-to-reach places can be difficult for most decontamination methods to penetrate, leaving those surfaces not contacted and potentially still contaminated.

Chlorine dioxide gas has a molecule size of 0.124 nm, which is smaller than the smallest known virus, porcine circovirus, which measures 13 nm in diameter.  With a molecule size 100x smaller than the smallest virus (coupled with the fact that chlorine dioxide is a true gas which fills the space its contained within evenly and completely) chlorine dioxide gas is able to reach and penetrate into all crevices within a space deeper than pathogens can reach.  This leaves dangerous pathogens with no place to hide, and leaves your facility with no place to worry about.

To learn more about how chlorine dioxide gas is able to provide a complete decontamination of all organisms / spores / pinworm eggs / beta lactams within the space, give us a call at 908-236-4100 or email us at

Biofilm Control

The control of biofilms within the food processing environment is a concern for anyone involved with food safety.  Biofilms can harbor and protect dangerous bacteria from traditional sanitation methods, leaving the environment at risk even after sanitation takes place.

To learn more about biofilms, we're thrilled to have Diane Walker, a Research Engineer at Montana State University's Center for Biofilm Engineering (CBE) present at this year's 2nd Annual Food Safety and Microbiology Conference in Dallas on February 27th.  Diane's presentation is entitled, "Biofilms: From Formation to Elimination" and will discuss the science of biofilms and methods of control. Diane received the 2015 CBE Outstanding Researcher Award in recognition of her commitment to the CBE Industrial Associates Program and contributions towards creating a quality Standardized Biofilm Methods research program.  Her current research includes biofilms within the food and beverage industries and we are incredibly lucky to have Diane join us at the Food Safety and Microbiology Conference

PPM-Hrs: Chlorine Dioxide Gas Treatment by Dosage

Previously, accurate measurement of other decontaminating agents was not consistent or reliable.  During large facility decontamination, it is not uncommon that the target concentration cannot be reached.  This may be due to loss, consumption, absorption or reaction with organic load. Since chlorine dioxide gas has a visible color, it is easily and accurately measured. This allows us to monitor the overall dosage accumulated during the decontamination and only complete the process once the correct dosage has been met.
To test this, ClorDiSys performed tests at different concentrations (0.3, 0.5, 1, 5, 10 & 20 mg/L) all with the same dosage. Dosage is described as an exposure at a concentration (parts per million) multiplied by an amount of time, typically hours (Hrs). For CD, this is referred to as PPM-Hrs. To determine the PPM-Hrs, the concentration in PPM is accumulated every minute. This accumulation then accrues PPM-Hrs. 6-log biological indicators were used to test the efficacy of chlorine dioxide gas when the overall dosage is held constant, but the concentration and contact times are varied. All of the varied chlorine dioxide gas concentrations (0.3, 0.5, 1, 5, 10 & 20 mg/L) with BI’s exposed to various exposure times with each cycle having a fixed target dosage of 720PPM-Hrs exhibited complete decontamination. The 20 mg/L run had the shortest gas time (14 minutes), and 0.3mg/L had the longest gas time (355 minutes). 
Data shows that the concentration of chlorine dioxide gas used does not affect the overall efficacy of the sterilization cycle as long as the overall exposure dosage of 720 ppm-hr has been met. Therefore, when the target concentration cannot be reached due to loss, consumption, or absorption, the cycle can still be successful. This confirms that the overall goal of an exposure is to achieve a certain dosage (720ppm-hrs) regardless of the concentration or exposure time.

Decontaminating Dry Processing Environments

Our proprietary chlorine dioxide gas is well suited for the decontamination of dry processing environments as it is a dry gas fumigation method.  As a true gas, it is able to completely fill the space it is introduced into evenly and completely, leaving no surfaces uncontacted.  Our pure chlorine dioxide gas does not leave behind a residue either, making it extremely safe for use within the processing environment.  It is also registered as a sterilant, proven to eliminate all bacteria, viruses, fungi and spores.

Sporicidal reduction is aided by the addition of moisture, with an optimal range of 65% RH and above.  This elevated humidity causes the hard-shelled spore to swell and crack open, allowing chlorine dioxide gas to enter into the spore and kill it. Even though this runs contrary to the theory of dry processing environments, raising the humidity level can be considered acceptable.  Following the introduction of moisture, a reliable and highly effective sterilant capable of eliminating all microbial life is introduced.  This sterilant, chlorine dioxide gas, would kill any microbes within the space wherever they may exist.  This includes cracks and crevices that are harder for traditional sanitation methods to reach and have efficacy within.

For those who still don't agree with the idea of raising humidity within a dry processing environment, studies show that humidity is not as necessary for the decontamination of salmonella and other non-spore forming bacteria.  Our chlorine dioxide gas has shown a 6-log reduction of salmonella typhimurium at 25% RH while using the standard concentration and dosage.

In either scenario, chlorine dioxide gas is a useful method of decontaminating dry processing environments.  It offers the most effective method of decontamination available across a number of different applications and environment types.  To learn about other applications within the food industry, please click here.

Visit us this week at the Food Safety Consortium in Chicago, where we'll be speaking during the Listeria Workshop taking place tomorrow from 9-12 CST, and exhibiting at table #124.

You can also visit us next week at the Food Quality Symposium in Palm Springs, CA.

Spiral Freezer Decon

Dr. Jeff Kornacki of Kornacki Microbiology Solutions, Inc says, "Spiral Freezers were designed by the devil to contaminate food with listeria."  While we've never seen a devil horn logo on any Spiral Freezers we've come across, the sentiment is there. They are a real pain for food manufacturing sites.

Spiral Freezers are a perfect storm for listeria growth.  They are constructed to minimize the inside chamber in order to reduce cooling costs, making them hard to clean using traditional sanitation methods.  There's an unhealthy amount of condensation and moisture within the freezer, which helps promote microbial growth by providing water to any organisms which find their way in.

Chlorine dioxide gas is uniquely situated to overcome the challenges of decontaminating Spiral Freezers.  Chlorine dioxide is a true gas at room temperature, meaning that it fills the space its contained within evenly and completely.  It also has a molecule size smaller than the smallest virus, allowing it to reach deeper into cracks and crevices than pathogens can hide.  Combining this with our Decontamination Service Team's experience in overcoming complex challenges and applications allows us to decontaminate Spiral Freezers quickly and effectively.  Earlier this year, our team was able to finally eradicate a listeria problem from a Spiral Freezer which had been shut down for 8 months.  The facility had employed the use of a number of different sanitation strategies: Ozone, Peracetic Acid, Heat, Enzymes, and even a different chlorine dioxide gas provider without being able to fully eliminate the problem.  After working with our team, the facility was able to get the Spiral Freezer listeria free and back into production.

Contact us for more information on how we approach Spiral Freezers and how we might be able to help out.
