Microbial Contamination and Mold Remediation in the Cannabis Industry

Molds, bacteria, and yeast are present everywhere, including in the air we breathe. Controlling mold and other pathogens is essential for any operation as it is a strong threat to cannabis, potentially wreaking havoc on crops. Microbiological contamination is more common than cultivators realize. They can get tracked in from anywhere at any time, and there is always some amount of mold spores in the air pretty much everywhere you go. According to California’s Bureau of Cannabis Control testing of 10,695 legal marijuana samples from July 1 through August 29, 2018, their findings produced 1,904 failed standards. This included 403 failures due to pesticides, 99 failures for residual solvents or processing chemicals, and 114 failures due to microbial impurities such as mold, E. coli, and salmonella. Decontamination is important to ensure a quality product reaches consumers.

Chlorine dioxide gas is the optimal solution for any decontamination scenario as it is a gas as room temperature, ensuring it will come in contact with every spore on every surface, even the tiniest of cracks and crevices. Ultraviolet light disinfection is a fast, simple to use, and chemical-free method, capable of providing a 99% reduction of spores within minutes. Depending on your operation, there are different challenges to preventing or eliminating contamination.

DECONTAMINATION OF EMPTY GROW ROOMS

Chlorine Dioxide Decontamination
Gaseous chlorine dioxide is an EPA registered sterilant that can be utilized prior to any plants entering the space to ensure any pre-existing mold spores be remediated. This significantly reduces the risk of cannabis crops “catching” any new mold spores. For a complete kill of all potential organisms in the entire facility, chlorine dioxide gas is the optimal way to fill an entire space evenly and completely, decontaminating every surface, crack, or crevice with no residues or additional cleanup.
Liquid chlorine dioxide can be sprayed, wiped, or mopped onto walls and floors, environmental surfaces, growing vessels, or chambers to eliminate any existing harmful organisms. Liquid chlorine dioxide can also be dosed into irrigation water or used in hydroponic systems to eliminate any contaminants. 

Ultraviolet Light Disinfection 
Ultraviolet light (UV-C) is an easy way to achieve high-level disinfection to any exposed surface in minutes. It also eliminates odors. This chemical-free and residue-free disinfection method will help reduce mold spores, therefore minimizing future risk of exposure to the cannabis plant. This is best utilized in a completely clear space to ensure maximum exposure to the UV-C light. If there are complex shapes to the space or objects in the space, the unit may need to be repositioned or multiple units may be needed to ensure as many surfaces as possible are exposed to the disinfecting light.

DECONTAMINATION OF SEEDS

Chlorine Dioxide Decontamination
A chlorine dioxide gas treatment of seeds can be completed in a chamber prior to use to deactivate any surface bacteria, mold, or other undesirable organisms. Because CD gas is a dry, residue-free sterilant, this will ensure that the seeds are in optimal condition and no longer pose risk to a plant developing mold during the growing phase. Utilizing a Tyvek pouch will allow the gas to penetrate through, keeping the seeds sterilized until ready for use.
Seeds can soak for mere minutes in a liquid chlorine dioxide solution to eliminate any surface contaminants that may be present. The removal of such contaminants will improve the future health of the plant by diminishing the risk of mold.

Ultraviolet Light Disinfection
UV-C can be applied to seeds utilizing a tabletop disinfection chamber. While the seeds are inside, they receive 360 degrees of UV-C exposure so long as they are spread out atop quartz glass shelving, limiting overlap and shadowed areas. A 99% kill on any surface mold will result without any undue harm to the seed, destroying any surface organisms that may cause mold issues in the future during the plants’ growth.

DECONTAMINATION OF PLANTS

Chlorine Dioxide Decontamination
If mold is present or forms while drying or being stored, chlorine dioxide gas can be utilized. ClorDiSys’ EPA-registered CD gas will inactivate all microbiological contaminants without leaving a residue. This treatment can be performed either in an enclosed chamber when only a select few plants are of issue or the decontamination of an entire room if there is a widespread outbreak. Prior to decontamination, users should confirm compliance with legislation.

Ultraviolet Light Disinfection
As a fast, high-level method of disinfection without the involvement of chemicals, ultraviolet light can be utilized in numerous ways throughout the growing process. This includes the elimination of odors. It can be used on a continuous, preventive basis to avoid the spread of any mold introduced or on an as-needed basis. Buds can be treated by UV-C light to eliminate mold that may grow on the surface during the drying and curing phases. UV-C light may be emitted via a wall unit or transportable device during the drying phase in order to destroy surface contaminants. At any point, including curing, the buds may be placed inside a UV-C disinfection chamber to receive direct 360-degree exposure quickly killing spores wherever the light shines.

At ClorDiSys Solutions, we take a broad look at your operation to determine the entry points for mold and other pathogens to provide expert advice and recommendations for environmental surfaces, tools, and the plants themselves. From creating stronger workflows to recommending new disinfection equipment and procedures, we aim to be a partner for your business.

Chlorine Dioxide Gas Decontamination versus Manual Wipe Down: Which is More Efficacious and Cost Effective?

 A sterile facility becomes compromised during annual maintenance shutdowns since outside equipment, tools and people enter the clean areas. Bausch + Lomb Vision Care has a production facility in Greenville, South Carolina where all contact solutions are manufactured in sterile processing areas. These solutions must be sterile since the drops will clean lenses or be placed directly in the eye. Therefore, it is critical that containers be filled and sealed in an extremely high-quality environment. To maintain sterility of the product, the environment is cleaned and then disinfected prior to resuming normal production following their annual shutdown.

This cleaning procedure in the past required over seventy-five personnel with mops and buckets and a minimum 3 days’ worth of time followed by a disinfection process utilizing multiple applications of a high-level disinfectant solution. This process is a costly (time and materials) method that uses over $100,000 of consumable cost to fully decontaminate the entire sterile processing facility and still had inherent failures since it was a laborious manual process. To reduce the failures and potentially reduce the costs, chlorine dioxide gas decontamination was investigated.

The gross cleaning and fine cleaning are still done prior to any gassing. Afterwards, the ClorDiSys decontamination team of five people arrived on-site early afternoon to unload the crates of equipment, setup manual chlorine dioxide gas generators, and begin sealing. After setup was complete, gassing began the next day around 4:30pm. The decontamination cycle was fulfilled, and the team was cleaned up and heading out by 1:30am. Resulting ppm-hours achieved from the decontamination cycle were adequate to provide a 6-log sporicidal reduction on the biological indicators after 36 hours of incubation. It was also a success from an economic point of view.  The costs of gassing or fumigating were slightly less than the traditional spray and wipe approach  With this cost savings, shorter down time, and better coverage of the decontamination agent, chlorine dioxide gas was selected as the company’s decontamination agent.

Read more about this application and comparison in Jennifer Longstaff's Pharmaceutical Engineering article. To start planning your complete decontamination during annual shutdown, contact us here.

Planning for the Safe Return of Employees and Customers Post-Pandemic

Across the globe, countries are beginning to phase into what will be their new normal after the COVID-19 pandemic. In the United States specifically, this includes allowing some "nonessential" businesses to reopen. Whether it is an office, a laboratory, a warehouse, a daycare, a gym, or a salon, extra precautions such as social distancing and symptom screenings can only do so much. Improving a facility's sanitation and contamination control is also key. ClorDiSys can help your company plan the safe return of employees and customers as your business reopens.

Ultraviolet light (UV-C) is an inexpensive, simple to use, chemical-free disinfection method effective against bacteria, viruses, fungi and spores. Whether it is in preparation for the return of employees and customers or for ongoing disinfection between shifts, meetings, or classes, the Torch UV-C disinfection tower provides a rapid and highly effective method to disinfect surfaces, components, room surfaces and common touch points to reduce the transfer of dangerous organisms such as coronavirus. In fact, the University of Nebraska Medical Center recently published their procedure for N95 mask disinfection using our Torch.



The Torch simply plugs into any standard wall outlet and contains eight high-powered, Teflon-coated UVC lamps to provide quick disinfection times. Each Torch produces an efficient UVC output of 12 mJ/minute (200 μw/cm2) to get a calculated 99% reduction of bacteria in 1 minute and spores like C.diff in 5 minutes making it ideal for the decontamination of all your company’s shared spaces including lobbies, conference rooms, cafeterias, bathrooms, and locker rooms.

Preparing for and Responding to Coronavirus in the Workplace

A new study from National Institutes of Health, CDC, UCLA and Princeton University scientists found that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was detectable in aerosols for up to three hours, up to four hours on copper, up to 24 hours on cardboard, and up to three days on plastic and stainless steel. The results provide key information about the stability of SARS-CoV-2, which causes coronavirus disease 2019 (COVID-19), suggesting people may acquire the virus through the air and after touching contaminated objects. Does your facility have a plan if one of your employees test positive for COVID-19?
 
Some international destinations as well as parts of the United States now have ongoing community spread with the virus that causes COVID-19. Community spread means people have been infected, and it is not known how or where they became exposed. Prevent the spread of coronavirus within your workforce by utilizing ClorDiSys Solutions’ high-level disinfection services in your facility’s high traffic areas. Our company offers three reasonably-priced decontamination options for all of your company’s shared space concerns including lobbies, conference rooms, cafeterias, bathrooms, and locker rooms.
  1. Electrostatic spraying with chlorine dioxide, minncare, sodium hypochlorite, or other agent of your choice to eliminate organisms on surfaces for pinpoint disinfection
  2. Electrostatic spraying with BioBlock 90, a disinfecting agent that doubles as a protection layer from organisms for up to 90 days
  3. Quick, chemical free, UV-C facility disinfection: UV-C is the killing spectrum of ultraviolet light proven effective against bacteria, viruses, fungi, and spores including SARS-CoV
Protect your team and your business from viruses, bacteria, spores, and other harmful organisms.

What Coronavirus Means for Mass Transit and other Public Spaces


On January 31, 2020, Health and Human Services Secretary Alex M. Azar II declared a public health emergency (PHE) for the entire United States to aid the nation’s healthcare community in responding to novel coronavirus (COVID-19). On March 11, 2020, WHO publicly characterized COVID-19 as a pandemic. The Centers for Disease Control and Prevention is working closely with state health departments on disease surveillance, contact tracing, and providing interim guidance for clinicians on identifying and treating coronavirus infections. What does this mean for the millions of Americans who count on buses, subways and commuter trains to get to work, school, and other daily activities?


The very thought of being in close or confined quarters with other passengers is cause for hesitation and potential panic. Transit agencies around the country have responded to the public health emergency by announcing expanded cleaning schedules, dispensing hand sanitizer, and equipping drivers with antiseptic wipes. These expanded cleaning schedules usually just involve wiping down the areas people mostly touch with a disinfectant, because wiping all the surfaces would take a lot of time and labor. There is an effective alternative option to the commonly use spray and wipe method, and that is fogging with chlorine dioxide.

Whether the fogging is completed by the ClorDiSys Decontamination Service team or the supplies are purchased for an agency or company’s staff to complete themselves, liquid chlorine dioxide is applied to surfaces using handheld foggers at concentrations capable of eliminating viruses, bacteria, fungi and spores. This method offers a level of disinfection comparable to utilizing Vapor-Phase Hydrogen Peroxide (VPHP). Handheld foggers are used to reach more surfaces than a stationary fogger, while changing the angle of application in order to minimize shadow areas not being contacted. This option can be used for buses, rail cars, and any other high-traffic public space, not limited to mass transit. Even companies in food and pharmaceutical production are creating COVID-19 response plans that include fogging offices, warehouses, and more.

The Newly Remodeled, More Powerful Flashbox-Mini

As of February 27, 2020, the novel coronavirus (abbreviated “COVID-19”) has an estimated global death toll of over 2,800, and it has invaded 47 countries, with California and Germany recording the first cases with no obvious source of transmission. The World Health Organization announced today, February 28, the coronavirus outbreak has reached the “highest level” of risk for the world. “This thing can go in any direction. We’re not undermining the risk, it’s there. That’s why today we said the global risk is very high. We increased it from high to very high,” Tedros Adhanom Ghebreyesus, director-general of the World Health Organization, said during a press briefing in Geneva Friday. Prevent the spread of novel coronavirus with the utilization of ultraviolet light disinfection for items of everyday use.

Ultraviolet light (UV-C) is a simple, chemical-free method of disinfection effective against bacteria, viruses, fungi and spores. ClorDiSys Solutions recently upgraded their Flashbox-mini ultraviolet light disinfection chamber, and the completely redesigned model has a greater intensity providing a higher level of disinfection in faster cycle times. The Flashbox-mini is a small, easily transportable chamber designed for use in any healthcare, pharmaceutical, manufacturing, laboratory, or research setting. It contains one quartz glass shelf to support the items being disinfected, generally tablet computers, phones, remote controls, miscellaneous electronics, instruments, and components, while not creating shadow areas or inhibiting the light’s ability to shine. The quartz glass shelf allows for complete coverage due to its unique ability of allowing UV-C to penetrate, unlike most other materials often seen such as wire, plastic or traditional glass. The chamber produces an efficient UV-C output intensity of approximately 1100 µw/cm2 achieving a 99.99% kill of spores like C. diff and a greater than 99.99% kill of bacteria such as MRSA and Hepatitis in 30 seconds on all visible surfaces. Not only does it reduce the transfer of dangerous organisms, but it also offers a way to disinfect components without removing them from the room, minimizing the chance for cross-contamination.

ClorDiSys Solutions’ years of experience in contamination and infection control across many industry types allows us to offer a unique blend of knowledge, experience, and methods that work. Contact us to discuss the best suited approach to improve your facility’s microbial contamination control and prevention.

Prevent the Spread of Coronavirus with Ultraviolet Light

The CDC is closely monitoring an outbreak of respiratory disease caused by a novel coronavirus (abbreviated “COVID-19”) that was first detected in Wuhan City, Hubei Province, China and continues to expand. Chinese health officials have reported tens of thousands of cases of COVID-19 in China. Some person-to-person spread of this virus outside China has been detected, and the United States reported the first confirmed instance of person-to-person spread with this virus on January 30, 2020. Not long after, the International Health Regulations Emergency Committee of the World Health Organization declared the outbreak a “public health emergency of international concernexternal icon” (PHEIC).

The novel coronavirus is a kind of positive-sense single-stranded RNV virus, same as the SARS and MERS virus. While the complete clinical picture with regard to COVID-19 is not fully understood, both MERS and SARS have been known to cause severe illness in people. Research on SARS found that this kind of virus is sensitive to ultraviolet (UV-C) light and can be diminished with exposure to UV-C irradiation stronger than 90 μW/cm2. Thus, in theory, UV-C light would be able to destroy the novel coronavirus.

Ultraviolet light has been used widely in disinfection with a wide range of medical and non-medical products available in the market. UV-C light is germicidal because it inactivates microorganisms by destroying nucleic acids and disrupting their DNA. Ultraviolet light not only kills the virus on surfaces but also those in the air. China is currently disinfecting some aircrafts as well as yuan bills with ultraviolet light as part of efforts to stop the spread of the coronavirus that has killed more than 1,500 people.

ClorDiSys Solutions has an ultraviolet light disinfection tower, the Torch, that is an inexpensive, easily transportable, powerful system that provides a rapid and highly effective method to disinfect surfaces, components, room surfaces and common touch points. Each Torch produces an efficient UV-C output of 12 mJ/minute (200 μw/cm2) to get a calculated 99% reduction of MRSA in 1 minute and Clostridium difficile spores in 5 minutes. In 2015, the Nebraska Biocontainment Unit (NBU) treated patients with Ebola virus disease evacuated from West Africa to the United States. Four Torch towers were used as the final disinfection step within those patients’ rooms and bathrooms. ClorDiSys also has a smaller version of this UV-C generator called the Lantern, designed for use within EMS vehicles and ambulances. Our line of ultraviolet light systems continues to grow and evolve to further support infection control efforts worldwide.

Preventing Contamination - Disinfect Your Incoming Air

Contaminants typically enter a facility through one of four ways: Air, Water, Supplies / Ingredients and People.  Over the next few months, we’ll highlight these vectors and discuss methods to help control them.  For our first post in this series, we’d like to talk about contaminants entering through the air.

Ambient air may be contaminated with or carry significant levels of a variety of potentially harmful microorganisms. There are three major sources of such microbes: a) those arising from microbial decomposition of various substrates associated with particular occupations (e.g., "moldy" hay leading to hypersensitivity pneumonitis), b) those associated with certain types of environments (e.g., Legionnaires' bacteria in water supplies), and c) those stemming from infective individuals harboring a particular pathogen (e.g., tuberculosis). As far as building ventilation design is concerned, the greatest impact of any ventilation design would be on the airborne route of contamination.   If there is no control system for incoming air to your facility, these contaminants can enter and distribute throughout your facility.  Two of the most common air quality control systems are ail filtration systems and ultraviolet light disinfection systems.

The most common types of air filters used for air quality control are Minimum Efficiency Reporting Value (MERV), High Efficiency Particulate Air (HEPA) and Ultra Low Particulate Air (ULPA) filters.  MERV ratings range from 1-20, with higher numbers offering better filtration.  HEPA and ULPA filters roughly correspond with MERV ratings of 17-20.  HEPA filters are rated to capture at least 99.97% of particles 0.3 microns (µm) while ULPA filters are rated to remove at least 99.999% of particles 0.1 micron (µm) or larger.  These systems are used in many critical environments to prevent contaminants or particulates from entering, and are available from a number of companies.  Related: ClorDiSys has validated the use of our chlorine dioxide gas to decontaminate Camfil’s Mobile Media Tester.

Ultraviolet light is a specific part of the electromagnetic spectrum of light that offers germicidal effects. Ultraviolet light is divided into UV-A, UV-B and UV-C rays. It is the wavelengths in the UV-C spectrum, specifically 265 nm, which offer the greatest germicidal potential. When a micro-organism is exposed to UV-C, the nuclei of the cells are altered due to photolytic processes. This process prevents further replication and causes cell death. As such, rather than trap pathogens and microbes like a filter, ultraviolet light kills them.

Ultraviolet light is typically placed in one of two locations in order to control pathogens within incoming air.  One location is inline with the supply air ductwork, disinfecting the air as it travels past the UV-C lamp.  Another application is using UV-C light to control organisms on the air handling system’s cooling coils.  UV-C light has been shown to reduce biofilms and control biofilm growth on cooling coils.  Biofilm growth on cooling coils has been shown to increase static pressure within the HVAC system which causes the system to work less efficiently to overcome that higher pressure.  Controlling these biofilms, in addition to supplying cleaner air, maintains the system's efficiency which in turn allows it to run better and save the facility money.  These have been shown to provide a cost savings greater than the cost of the UV-C system itself.

ClorDiSys offers the AirGlow™ as an in-duct ultraviolet light disinfection system that can be installed in any HVAC system. The AirGlow can help reduce and/or eliminate the growth of bacteria, mold and spores on supply and return airflow. Designed for continuous and long-term use, the AirGlow is constructed out of corrosion-resistant stainless steel and uses UV-C lamps with a lifespan of 13,000 hours (approx. 18 months). As air passes the quartz glass UV-C bulbs of the AirGlow, the travelling air is disinfected, and harmful organisms that may have been present are killed. It provides continuous disinfection without special attention or risk of exposure to people in rooms being handled by the ductwork.

Establishing a Clean Break in Production

A clean break is a defined production break that involves a documented, verified, and validated cleaning and sanitation process of all food/product contact surfaces. Clean breaks are used to establish lots to trace their products and limit the quantity or product recalled in case of a contamination. Similar to a firebreak in a forest, a clean break gives you that line of safety.  Some municipalities will clear out a section of the forest to act as a “clean break” so that in case of a fire, you have a line of containment already in place. Preventive measures are always hard to value, because like insurance, it is hoped to be a sunk cost that has no return on investment. However, if it is used, its value is tremendous.

Now the problem is, what happens if you cannot defend your clean break? If your clean break cannot be defended during a recall, then as far as an investigator is concerned, you didn’t have one.  When that happens, your recall will grow. In October 2018, McCain Foods recalled 63 different products back to a shipped date of January 1, 2016 because they didn’t have a more recent clean break. In order to defend your chosen sanitation method, you must understand decontamination and sterilization. The traditional sanitation methods do kill – you see the log reduction right on the label of the products – 99.9% antibacterial, and so on. However, these methods can have difficulty guaranteeing that all organisms have been contacted or contacted with the proper effective dosage. Even ozone, which is an effective method, doesn’t hold the concentration very long, which makes it difficult to do larger areas. Alternatively, chlorine dioxide gas is able to achieve a complete 6-log sporicidal decontamination of all surfaces within a space, including hard-to-reach areas such as cracks and crevices, because it is a true gas above -40 degrees and its molecule size is smaller than the smallest virus. Because ClorDiSys Solutions’ process is pure and dry, our chlorine dioxide gas doesn’t leave a residue. Once the gas has been removed, the area is safe and does not require additional cleanup. ClorDiSys’ approach to process control has enabled us to be trusted to keep critical environments safe, including 31 of the Top 100 food manufacturers.
