Medizone International Announces Successful Completion of First Round of Hospital Beta-Testing for AsepticSure™

KINGSTON, ON--(Marketwire - October 21, 2010) -  Medizone International Inc. (OTCBB: MZEI) (OTCQB: MZEI) announced today successful completion of the first phase of AsepticSure™ beta testing at Hotel Dieu Hospital, an ambulatory care teaching and research hospital affiliated with Queen's University in Kingston, Ontario, Canada.

Dr. Michael E. Shannon stated, "We are absolutely delighted with the results. Pre-inoculated stainless steel test discs as well as carpet swatches typically found in many health care facilities were placed in selected locations to assess for antimicrobial effects. Not only were 100% of the MRSA and C. difficile spores eliminated from the stainless steel discs (7.1 logs bacterial kill for MRSA and 6.2 log bacterial kill for C difficile spores), the pathogens were also completely eliminated from all contaminated carpet samples, something unachievable with any other technology we are aware of. Thus, the system performed to our highest expectations. The AsepticSure™ system has proven to be able to achieve a very high level of microbial kill to the sterilization standard of > 6 log (99.9999%) in the laboratory setting and now in a hospital setting."

Dr. David Pichora, a leading orthopedic and hand surgeon, and the hospital's Chief Executive Officer, observed, "I am pleased that Hotel Dieu Hospital has been able to participate in what appears to be a promising breakthrough in addressing the global challenge of reducing hospital acquired infections. The results of the AsepticSure™ sterilization technology tests are encouraging. Technology that could help hospitals improve patient safety, reduce infection rates and reduce costs is exciting, indeed. We are pleased to be participating in this safety initiative and we look forward to continued participation."
