  • Slide 3
  • Similarity in Maintaining Biosecurity and Suppressing Microbial Populations in Food-Animal Production Units and Hospitals. Rooms in hospitals and food-animal production facilities are periodically cleaned and disinfected, which greatly reduces microbial populations at that instant Rooms must be vacated of humans and animals for 24 hours after disinfecting for safety (most disinfectants are carcinogenic) until disinfectant decomposes. Most disinfectants are worthless within 24 hours of use When humans enter hospital rooms and sows enter farrowing units, microbial counts increase and disease virulence builds. Most serious disease vectors are humans in hospitals and sows in farrowing units. Need a prophylactic that continues to suppress microbes for extended periods and is safe. Selected trace minerals provides such protection. Mineral elements do not break down. Culmination of research to minimize nosocomial diseases of humans within hospitals and minimize diseases of food-producing animals is done with programmed use of selected mineral elements. Hospitals are methodically installing copper, zinc and iron surfaces that have excellent microbial inhibiting power, to replace attractive stainless steel that is worthless in eliminating microbes In food-animal production, programmed dusting (i.e. weekly) all surfaces with copper, zinc, and iron provides the same sustained suppression of microbes
  • Slide 4
  • Purpose of Disrupt Environmental Prophylactic Contains trace elements that continuously reduce microbial levels throughout farrowing and nursery Research that developed Disrupt paralleled research conducted by medical and hospital scientists to reduce nosocomial diseases (fancy term for diseases contracted from going to hospitals) Our research and hospital research concentrated on using trace mineral elements to inhibit organisms from viruses through bacteria, molds/fungi and larval stages of insects and parasites.
  • Slide 5
  • Two Important Research Journals: Journal of Hospital Infections Journal of Applied and Environmental Microbiology Many trace mineral elements have been investigated but copper, zinc and iron are by far the most effective We have focused on the same trace elements: Cu, Fe, and Zn We have developed an extensive library of research demonstrating efficacy of each of the 3 elements Examples of our research and hospital research against a broad spectrum of microbes

  • Antiviral Effect of Iron and Copper Quotes by Author at FDA Both iron and copper ions were able to inactivate Junin virus comparable to the activity of recommended disinfectants: formaldehyde, peroxide, and chlorine Sagripanti US FDA 1992 Ferric and cupric ions were able to inactivate 5 single or double stranded DNA or RNA viruses. At least 99% inactivation of all 5 viruses was obtained with 1 g/liter of either ferric or cupric ions Sagripanti US FDA 1993 HIV-1 virus was inactivated by either ferric or cupric ions when the virus was free in solution and also 3 hours after cell infection Sagripanti US FDA 1996 Sagripanti was studying viral laboratory management and did not pursue potential broad spectrum disinfectant application

  • Copper Effective at Inactivating H1N1 Virus H1N1 Virus was Incubated on Copper or Stainless Plates Stainless Steel Plates After 24 hours, there were still 500,000 infectious particles Copper Plates After 1 hour, 75 % of virus was eradicated After 6 hours, only 500 particles remained active. Keevil, Wm 2009

  • Copper Effective at Inactivating Adenovirus Virus Adenovirus was Incubated on plates: Copper Stainless Steel Initial Virus Particle Number 2,000,000 2,000,000 After 1 hour 500,000 After 6 hours 500 1,000,000 After 24 hours 0 500,000 Noyce, J.O., H. Michels, and C.W. Keevil, 2007. Inactivation of influenza A virus on copper versus stainless steel. J Applied Environ Microbial Vol 73:2748. H1N1 virus titer decreased by 4 log on the copper surface within 6 hours. 75% of adenovirus particles were inactivated on copper (C11000) within 1 hour. Within six hours, 99.999% of the adenovirus particles were inactivated. Within six hours, 50% of the infectious adenovirus particles survived on stainless steel.

  • Quotation by C. W. Keevil Southhampton University, UK Lead Scientist in research to Determine Efficacy of Mineral Elements antiseptic against Microorganisms. Has confirmed efficacy of Fe, Zn, and Cu Quote: "We've already shown that copper surfaces can inactivate MRSA microbes. The fact that we've now established that copper also inactivates Clostridium difficile spores, which are resistant to standard cleaning regimes, doubles our conviction that copper can play significant role in killing those bacteria that cause hospital infections."

  • Press Release, Brussels, Belgium. 1/12/2010 Irish hospital is first in world to embrace latest science by specifying hygienic copper door handles throughout Irish Hospital. First to harness Copper Technology to Fight Infections in a bid to reduce healthcare associated infections such as MRSA, providing best possible protection to patients. St Francis Private Hospital, a 140-bed facility located in Mullingar, County Westmeath, made decision after examining compelling evidence from clinical trial at Selly Oak Hospital, Birmingham, which showed that copper surfaces such as taps, toilet seats and door push plates can reduce microbial contamination by 90-100%. A total of 250 door handles will be replaced at St Francis Private Hospital.

  • First Hospital in France Installs Antimicrobial Copper Touch Surfaces to Combat Nosocomial Diseases October 7, 2011 Press Clipping The Centre hospitalier de Rambouillet, in Parisian region, is first hospital in France to install antimicrobial copper touch surfaces to fight pathogens and reduce risk of healthcare-associated infections for its patients. Bed rails, trolleys, taps, handrails, door handles and push plates made of copper and copper alloys have been fitted in the intensive care and pediatric units. Antimicrobial copper touch surfaces are proven capable of continuously eliminating bacteria, viruses and fungi including MRSA, C. difficile and Influenza A 24/7, from clinical environments. Now add St Lukes Hospital in St Louis MO to the list (In Progress)

  • Action by US Environmental Protection Agency U.S. EPA approved registration of antimicrobial copper alloys, with public health claims acknowledging that copper, brass and bronze are capable of killing harmful, potentially deadly bacteria. Bacteria listed in EPA registration: Staphylococcus aureus Enterobacter aerogenes Escherichia coli O157:H7 Pseudomonas aeruginosa Methicillin-resistant Staphylococcus aureus (MRSA), (one of most virulent strains of antibiotic-resistant bacteria and common cause of hospital- and community-acquired infections) EPA has developed a list of 300 items in health care facilities that can be registered when made of copper alloys. (From ash trays to ceiling tile)
