An audit conducted by BDIC also verifies whether participating businesses follow local and federal public health regulations.

  • How does BDIC identify bacteria?

    Bacteria are covered by a thin, hard outer layer called the S-layer that protects the bacteria from the environment. The S-layers in bacteria cells are composed of an array of two-dimensional proteins with a crystalline structure. BDIC detects these protein shells with the help of high calibration LED wavelengths that work at the edges of the UV spectrum. By utilizing four separate UV wavelengths, once merged, will bounce off the protein crystal and emit an unmistakable green glow, often described as a green hue. Bactiscan’s™ unique wave altering UV system enables users to immediately identify and isolate biofilms, mold, and bacteria such as listeria, E. coli, salmonella Montevideo and pseudomonas Aeruginosa.

  • What is BDIC Monitoring?

    BDIC monitoring is a rapid examination technique widely used by food and beverage processors to determine whether product contact and equipment surfaces are clean. Using wave alternating UV technology, BDIC detects bacteria, biofilms, mold, and organic residues on surfaces. The presence of these on the surface indicates improper cleaning and contamination, including the presence of food residue, allergens, or bacteria. As a result, the surface may harbor and support bacterial growth. It is used in food and beverage processing facilities and many industries to minimize contamination through effective sanitation processes. In addition, the BDIC monitoring system ensures the integrity and shelf life of products and protects the reputation of brands.

  • Are many food and beverage processing companies using BDIC?

    The BDIC system is used around the globe and is recognized by food and beverage processors for validating cleaning processes in compliance with government and HACCP regulations

  • How many healthcare facilities use BDIC monitoring?

    BDIC monitoring systems are used in many hospitals worldwide to measure cleanliness. It is expected that the proportion of hospitals utilizing BDIC monitoring will continue to rise as hospitals battle rising healthcare-associated infection (HAI) rates and increasing demand for cleaner facilities.

  • What studies and white papers have been published on BDIC testing?

    The BDIC has been independently validated by scientist the leading international food testing, and safety laboratory, (Assessment of BDIC instrument for detection of food industry biofilms – November 2020) and proved the BDIC to be effective in detecting surface bacterial contamination. In addition, the Bactiscan’s efficacy has been solidly established through its continuous use by some of the world’s largest food production, dairy, brewery, and pharmaceutical companies.

  • What is a biofilm?

    In a receptive environment, surface biofilms are formed when microorganisms are exposed to moisture and food. Through the secretion of sticky polymers, populations of microorganisms attach themselves to surfaces. As long as the biofilm persists, sanitizers are ineffective since the bacteria are protected by the matrix and reinforced by it. As a result, biofilms can decrease the quality of products and cause loss of products due to contamination, and consequently cause equipment and product damage. By identifying food residue early and removing it, you can limit the potential for biofilm formation by eliminating the source of microbes that might form biofilms.

  • When should I do BDIC testing?

    Unlike ATP testing, you have the flexibility to before or after or before and after cleaning and sanitization. Also, unlike ATP, the use of sanitizers will not affect the accuracy of the BDIC device.

  • Is there a difference between cleaning, disinfection, and sterilization?

    Cleaning involves removing organic material and reducing the likelihood of contamination or microbial growth. Microbiological hazards can be reduced by disinfection to a minimum, but not necessarily eliminated completely. Sterilization destroys and inactivates all microbial hazards.

  • How should the testing be conducted?

    In contrast to other monitoring technologies, BDIC quickly scans all surfaces, including food-contact zones (direct and indirect). Any contaminants present on direct contact surfaces can contaminate the final product. The indirect contact points are those where dust, liquid, or splashed product has the potential to drip, drain, or transfer to the end product. Filler heads, O-rings, nozzles, and surfaces with irregular shapes, corners, grooves, and cracks can be among the hardest to clean.

  • Must a surface be dry before I can illuminate it with the BDIC?

    Surfaces do not have to be dry to perform a BDIC test. However, for consistency, consider scanning surfaces in the same conditions (either always wet or always dry).

  • Why is BDIC testing a better way to verify cleanliness?

    In healthcare facilities, visual inspections are no longer sufficient to ensure cleanliness. BDIC testing is becoming increasingly popular among healthcare professionals around the globe as a means of assessing the cleanliness of surfaces and medical instruments after they have been cleaned. In the old method of cleaning verification, a supervisor would visit a room after a patient was discharged and mark surfaces with a fluorescent gel pen. Once the environmental services staff had completed cleaning the room, the supervisor would visit the room to inspect the surfaces. During this inspection, a supervisor wasted valuable time, and the assessment was not measurable, and it held up room turnover. Using BDIC, supervisors only need to visit a room once. In addition, BDIC surface scanning takes a few seconds and can objectively quantify the cleanliness of a room. This process enables rooms to be turned over more quickly, supervisors to accomplish more work, and cleaning staff to be held accountable with actual, quantified data.

  • To monitor my hospital's and other facilities’ cleanliness, how many scans should be performed?

    In contrast to ATP monitoring, BDIC monitoring offers flexibility in tailoring and integrating into your cleaning and sanitization protocols. As an alternative to ATP monitoring systems, Bactiscan can easily be used to determine the efficacy of cleaning before and after the cleaning process. There is a strong recommendation made by the manufacturers of ATP swabs not to use the swabs on dirty or soiled surfaces, as they always result in Fail results for the test. Although they do make an exception for sanitation companies and chemical suppliers who use pre-clean and post-clean ATP tests to demonstrate the effectiveness of cleaning products, they mention that these tests are not to be confused with regular ATP monitoring programs. Additionally, they emphasized that ATP monitoring should only be performed after cleaning and not before and after cleaning. ATP manufacturers, also state that hospitals do not need to monitor every single location available, but only a statistically representative sample in order to gather sufficient data for reporting and results in interpretation. Those recommendations are troublesome and are a major difference between Bactiscan monitoring and ATP monitoring because those recommendations increase the risk of statistically significant contaminations. Can the Bactiscan system detect Methicillin-resistant Staphylococcus aureus (MRSA) or Clostridium difficile (C. diff) on a surface? No, not specifically. Microbiological testing methods, which can take several days to produce results, are the only way to identify MRSA and C. diff. The Bactiscan environmental system only detects the presence of bacteria, biofilms, mold and organic materials on surfaces, not specific strains of bacteria. If surfaces are cleaned properly, they will not have the organic material needed to foster bacterial growth.

  • Can the BDIC system be used to verify the cleanliness of reusable items like endoscopes and surgical instruments?

    The BDIC provides a high-sensitivity method for detecting surface contamination, suitable for sterile services. Using BDIC testing before terminal sterilization ensures the endoscopes and surgical instruments have been thoroughly cleaned and is ready for terminal sterilization. To verify the cleanliness of endoscopes, the BDIC can be used in conjunction with ATP test devices. The ATP test device cannot swab the entire surfaces of the endoscope or surgical instruments. This can be quickly and accurately performed by the Bactiscan. An EndoSwab sample collection device is then used to collect samples from the main endoscope channel to determine if the internal channel has been effectively cleaned.

  • Can the BDIC be used to test the effectiveness of UV, Ozone, or Hydrogen Peroxide Vapor (HPV) room sterilization?

    Using UV, Ozone, or HPV to kill bacteria will usually produce lethal results on surfaces. Each of these technologies recommends thorough cleaning before application, so in order to ensure successful sterilization. Therefore, cleaning thoroughness should be verified before sterilization. Using BDIC testing before terminal sterilization ensures the room has been thoroughly cleaned and is ready for UV, Ozone, or HPV sterilization. In addition, BDIC testing should be used after terminal sterilization to ensure cleaning has been thoroughly performed because sometimes UV light sterilization tools are not producing the appropriate UV levels to perform effectively, thus leaving residual microbes on the treated surfaces. Therefore, using a BDIC, you can determine whether the UV sterilization tools you are using are consistently and effectively destroying viruses and bacteria, by the presence of microbial residues on the surfaces after terminal sterilization.

  • Why is the BDIC environmental monitoring system cost-effective?

    The BDIC is well-priced and does not require any consumables. Furthermore, BDIC increases the accuracy and reduces the cost of conventional microbial detection methods. In addition to preventing infectious complications for consumers and patients, BDIC also saves money by reducing product loss due to contamination.

  • Does the system need to be calibrated?
