Food Safety

Chlorine dioxide gas (CD gas) is the most effective method of decontamination available. It offers the ability to reach and eliminate all organisms within a space, even in hard to reach areas and harbor locations. As a true gas, CD gas fills the area it is introduced into evenly and completely, ensuring that all surfaces receive an equal dose and equal kill level. The CD gas molecule is smaller than all microorganisms, so there are no crevices or harbor locations where microorganisms would be protected from CD gas. Effective in both dry and wet conditions, chlorine dioxide gas has been used by the dairy, produce, meat, grain, spice, frozen, and beverage industries.

CD gas has been used for the decontamination of facilities, tanks, rooms, laboratories, piping systems, spiral freezers, containers, cargo trailers, and tented pieces of equipment for many years. As a residue free process, CD gas is safe for use on food contact surfaces and is even on the National Organic Program's List of Approved and Prohibited Substances as an approved substance for use on organic foods. ClorDiSys has also been approved by the FDA for antimicrobial fruit and vegetable rinses in both the gaseous (Food Contact Notice 1421) and liquid (Food Contact Notice 1400) states with more approvals in the works now.

The CD Gas Advantage

  • ClorDiSys' CD Gas is an EPA registered sterilant, making it effective against all viruses, bacteria, fungi and spores

  • Non-carcinogenic, residue free process

  • True gases are the only agents effective in hard to reach areas such as HVAC systems, cracks and crevices, and inside equipment.

  • Safe on materials such stainless steel, anodized aluminum, painted steel, plastics, epoxy flooring and paints, gasket materials, and electronics

Common Industry Applications

Chlorine dioxide gas fills the space it's contained within completely and evenly, ensuring that no matter how large the target space is, no surface is left untouched; including crevices and harbor locations. We have decontaminated facilities over 1,500,000 ft3, providing 6-log sporicidal kill throughout.

For applications where the entire room does not need to be decontaminated, equipment can be tented and fumigated in place. This allows for a smaller volume to be treated, lowering treatment times and costs compared to decontaminating the entire room. With a proper seal, production and other work can take place in the same room as the tented equipment undergoing decontamination.

Tented Production Line Tented Equipment

Chlorine dioxide gas has been shown effective at eliminating listeria from within spiral and tunnel freezers. One facility which produced frozen sausages has a persistent listeria problem, resulting in consistent positive swabs. After one treatment with CD gas, the facility was able to eclipse 16 weeks without a single positive swab after testing 2-3 times per day. CD gas decontamination has been written into a quarterly preventive maintenance schedule.

Spiral Freezer Spiral Freezer

Chlorine dioxide gas fills the space it's contained within completely and evenly, ensuring that no matter how large the target space is, or how much equipment is within the space, no surface is left untouched. Traditional room decontamination times are approximately 2.5-3.5 hours depending on their size and the accompanying air handling unit.

Examples of room types decontaminated with chlorine dioxide gas are:

Production Rooms
Packaging Rooms
Cold Storage Rooms
Controlled Atmosphere Rooms
Gowning Rooms
Bottling Areas
Micro Labs
Airlocks and Passthrough Rooms

Laboratory Production

A company purchased a used bacon slicing line for their facility. They chose to decontaminate the equipment inside of a trailer with CD gas to ensure that it was sterile before allowing it to enter their production area. The trailer acted as a decontamination chamber, allowing for the quick, easy, and safe decontamination of the equipment outside of the facility. Leaving no residue, the equipment was immediately able to be brought into the facility upon completion and put into production.

In another instance, a food transport truck trailer was determined to have been contaminated with Salmonella from a shipment of food. The truck was decontaminated with chlorine dioxide gas over the course of 3 hours. Swabbing showed complete eradication of the organisms, and the trailer was put back into service for the safe handling of food.

When fumigating an area with CD gas, chlorine dioxide will penetrate the drain and decontaminate up to the water line of the P-trap. For drain systems without a P-trap, the gas will travel further down and decontaminate the drain system. Small amounts of water within the drain and piping will not affect the efficacy of the decontamination as CD gas is water soluble and retains its efficacy within water. While water soluble, it takes a long time in order to penetrate greater depths of water, such as the amount of water within a P-trap. CD Gas has been shown capable of eliminating biofilms, making the treatment of drains and pipes advantageous.

We also can provide a liquid chlorine dioxide product which can be used to treat drains. In these circumstances, the drains are capped or plugged and then filled with liquid chlorine dioxide in order to provide kill within the drain system.

Drain Piping System

Traditional sanitation procedures typically do not include Air Handling Units or their accompanying ductwork. When decontaminating with CD gas, it is often times very easy to include the ductwork and air handling system (even HEPA housings) in the scope of the project. CD gas penetrates through HEPA filters as if they are not there, and being a dry gas it is able to navigate the bends and turns of the ductwork system without condensing and getting "stuck."
