In industries such as food processing, pharmaceuticals, and cold storage, maintaining hygiene and preventing cross-contamination are critical. Cold rooms, where temperature-sensitive products are stored, can pose unique challenges for hygiene management due to the high traffic of people and goods entering and exiting the environment. This is where sanitising tunnels come into play. These tunnels, designed to disinfect individuals and objects before entering controlled environments, have emerged as a potential solution to mitigate contamination risks. But how effective are they in cold rooms? Learn more about their effectiveness through this article, including a case study from Ireland, to provide a well-rounded understanding.
Understanding the Role of Sanitising Tunnels
Sanitising tunnels are automated systems installed at the entrance of controlled environments, such as cold rooms, food processing plants, and pharmaceutical facilities. The purpose of these tunnels is to spray a sanitising mist or disinfectant on individuals or objects passing through, reducing microbial load and preventing potential contaminants from entering critical areas.
The primary goal is to prevent cross-contamination, especially in environments where maintaining cleanliness is essential to avoid spoilage or safety risks. In cold rooms, where food and other perishable items are stored at low temperatures, the risk of bacterial contamination or mould growth is heightened, making hygiene control measures like sanitising tunnels crucial.
How Do Sanitising Tunnels Work?
Irish sanitising tunnels operate with a series of nozzles that spray a fine mist oI f disinfectant solution as people or goods pass through. These disinfectants are typically non-toxic and fast-acting, ensuring safety for both the individuals exposed and the products within the cold room.
The process usually involves:
- Sensor activation: When an individual or trolley enters the tunnel, sensors trigger the spray system.
- Misting: A disinfectant mist covers all surfaces, targeting both external clothing and objects like crates or equipment.
- Disinfection time: The exposure time is typically short, ranging from a few seconds to about 30 seconds, depending on the system used.
- Completion: Once the individual or object exits the tunnel, they have been disinfected and are ready to enter the controlled area.
The idea behind the cold room disinfection tunnel is that by addressing external contaminants at the point of entry, the tunnel effectively reduces the chance of harmful bacteria or viruses entering the cold room environment.
The Effectiveness of Sanitising Tunnels in Cold Rooms
While sanitising tunnels have become a popular solution, how effective are they in preventing cross-contamination in cold rooms? Several factors influence their effectiveness, from the type of disinfectant used to the frequency of tunnel use.
1. Surface Coverage and Microbial Reduction
One of the most important factors determining the effectiveness of sanitising tunnels is the coverage of the disinfectant on individuals and surfaces. Studies have shown that tunnels that ensure even misting of disinfectant can significantly reduce the microbial load on surfaces, including clothing, footwear, and equipment.
In cold rooms, where air circulation is limited and contaminants can linger, the disinfection of incoming personnel is vital. Sanitising tunnels create a barrier against pathogens that could otherwise be introduced by workers or products. However, their effectiveness is dependent on regular maintenance, proper use, and ensuring that all areas, including underfoot, are sufficiently disinfected.
2. Prevention of Cross-Contamination
Cross-contamination, the process by which bacteria or viruses spread from one surface to another, is a constant threat in environments where goods are stored or processed. In cold rooms, contaminated goods or individuals can easily spread pathogens to other items, resulting in spoilage or safety hazards.
Sanitising tunnels effectiveness has been demonstrated in preventing this kind of cross-contamination. By sanitising both people and trolleys entering the cold room, the chances of pathogens being carried inside on clothing, shoes, or equipment are greatly reduced. This can significantly lower the risk of contamination spreading throughout the cold room, safeguarding the products stored inside.
3. Integration with Other Hygiene Protocols
For sanitising tunnels to be truly effective, they must be part of a broader hygiene management system. While they are excellent at reducing the microbial load on external surfaces, they do not replace other essential hygiene measures, such as proper hand washing, cleaning protocols within the cold room, and regular disinfection of surfaces.
In Irish cold storage facilities, for example, tunnels are often used alongside foot baths, hand sanitiser stations, and air filtration systems to ensure maximum contamination control. Cold room disinfection tunnels complement these other methods but should not be seen as a standalone solution.
Case Study: Sanitising Tunnels in Irish Cold Rooms
Ireland has a robust food processing industry, with cold storage facilities playing a vital role in ensuring the quality and safety of food products. To explore the real-world effectiveness of sanitising tunnels in preventing cross-contamination, let’s examine a case study involving an Irish dairy processing plant.
The Problem
In early 2022, an Irish dairy company experienced an issue with frequent contamination in their cold storage facility. Despite adhering to standard hygiene protocols, they observed occasional spoilage of stored products, particularly cheeses, leading to significant financial losses. Upon investigation, it was found that the contamination was likely being introduced by staff and equipment entering the cold room from other areas of the plant.
The Solution
In response to this issue, the company installed sanitising tunnels at the entrance of the cold room. The tunnels were designed to spray a food-safe disinfectant mist on employees and equipment entering the cold storage area, reducing the likelihood of bacteria being carried into the cold room.
Additionally, the company implemented a strict hygiene protocol that required all personnel to pass through the tunnel before entering the cold room, alongside regular sanitisation of storage areas and equipment.
The Results
Six months after the installation of the cold room disinfection tunnel, the company reported a significant reduction in contamination incidents. The spoilage of dairy products decreased by over 70%, and the company saved thousands of euros in lost product.
Feedback from the staff was also positive, with many reporting that the sanitising tunnel was easy to use and did not slow down their workflow. The company also received certification from a hygiene auditing body, confirming the improved standards of cleanliness in their cold storage area.
This case highlights how sanitising tunnels in Ireland can be highly effective when combined with other hygiene measures, reducing the risk of cross-contamination in critical environments such as cold rooms.
Challenges and Considerations
While sanitising tunnels offer numerous benefits, there are challenges to consider.
1. Cost and Maintenance
Sanitising tunnels can be a significant investment, particularly for small to medium-sized businesses. The upfront costs, along with the need for regular maintenance to ensure the system functions properly, may deter some companies from adopting the technology. However, these costs must be weighed against the potential savings from preventing product spoilage and contamination.
2. Effectiveness Against All Contaminants
While sanitising tunnels are effective against many common pathogens, they may not be equally effective against all types of contaminants. For instance, the type of disinfectant used can influence whether the tunnel can eliminate specific bacteria or viruses. In high-risk environments, it’s important to use tunnels that are tailored to the specific microbial threats of the industry.
3. User Compliance
The success of sanitising tunnels also depends on consistent use. If staff or suppliers bypass the tunnel or fail to follow the proper procedures, the risk of contamination remains. Therefore, training and compliance are essential for maximising the effectiveness of sanitising tunnels in preventing cross-contamination.
