Identification by Quantitative Carrier Test of Surrogate Spore-Forming Bacteria To Assess Sporicidal Chemicals for Use against Bacillus anthracis: Miles R. Majcher, Kathryn A. Bernard, and Syed A. Sattar
The spores of six strains of Bacillus anthracis (four virulent and two avirulent) were compared with those of four other types of spore-forming bacteria for their resistance to four liquid chemical sporicides (sodium hypochlorite at 5,000 ppm available chlorine, 70,000 ppm accelerated H2O2, 1,000 ppm chlorine dioxide, and3,000 ppm peracetic acid).
Excerpt:“The sporicidal activity of a given formulation is only one among a set of features to be considered in dealing with any decontamination scenario. Human and environmental safety, as well as materials compatibility, are among the other factors to keep in mind. Though bleach is fast acting, inexpensive, and generally readily available, its main drawbacks are off-gassing inactivation in the presence of organic loads and high corrosivity. In contrast, AHP-based formulations are reasonably fast acting and also have much-higher materials compatibility, while being less toxic to humans and the environment (8).”
Enhancing Patient Safety through the Management of Clostridium difficile at Toronto East General Hospital (319 KB): Healthcare Quarterly, 9(Sp) 2006: 50-53 Arladeen Tomiczek, C. Stumpo and James F. Downey
In 2005 Toronto East General Hospital experienced a steady increase in the number of C. difficile cases diagnosed within the hospital. This was identified as a patient safety issue, and several areas of the hospital came together to address the problem. Pharmacy immediately started a medication review of past cases. Environmental services took the lead on the environmental cleaning, and a process was put into place with Infection Control so that housekeeping knew of every room that contained a p
Efficacy of Two Hydrogen Peroxide Teat Disinfectants Against Staphylococcus aureus and Streptococcus agalactiae (76 KB): K. E. Leslie,1 E. Vernooy, A. Bashiri, and R. T. Dingwell
An experimental teat dip containing 0.5% hydrogen peroxide as the active ingredient was compared with a teat disinfectant also containing 0.5% hydrogen peroxide that is commercially available throughout North America.
Excerpt:“These findings suggest that the test teat disinfectant provided germicidal activity similar to that of the positive control teat disinfectant. Average teat skin condition scores were significantly improved when the experimental disinfectant was applied over the 10-wk study period.” pg. 6

Excerpt:“In the 1990s, when the green movement was in its infancy, end users would actually pay a premium for products considered green. However today, with regulations, restrictions, general awareness and massive recycle initiatives, it is largely presumed by clients that companies will offer them products that are friendly or friendlier. Also the premiums paid in the past are all but gone. Green is no longer a differentiator, it is a responsible and necessary component of any chemical company strategy. Finally, those that choose to use an eco-labelled product should do so with the confidence and assurance that an arms length body has performed due diligence and accepted the product. Then let performance be the judge.” pg. 6
Human Avian Influenza: A sanitation perspective (1.20 MB): Nicole Kenny, Virox Technologies Inc.
Excerpt:“Many people, certainly the international media, are looking at what is now primarily a viral infection of birds, and predicting a doomsday scenario sufficient in scope to remove almost half of humanity from the face of the earth. In the worst case hypothesis, our hospitals will quickly swell beyond a rapidly diminishing capacity, workplaces will be abandoned grinding commerce to a halt, any large public gathering will be disbursed by public order, transit systems will shut down, face masks will be haute couture, and instead of shaking hands in casual greeting we will bump elbows. The good news is that this doomsday scenario is about as likely as the Chicago Cubs winning the World Series. The bad news is we need to get busy working on a plan for “the just-in-case.”” pg. 1
