Copper for Nosocomial Prevention

Copper is a potent anti-microbial agent in water – which is why it is so effective in copper silver systems to control Legionella. Recent studies show it may also become the best way to prevent bacterial infections on contact surfaces in hospitals.

Nosocomial (hospital-acquired) infections, like Legionnaires Disease and MRSA, affect millions of people every year. Many nosocomial infections are spread by contact surfaces like bed-rails.

But there is hope to stop this deadly spread of bacteria, thanks again to copper.

In a recent article from NPR, Constanza Correa, a Chilean scientist, shares her research on the effect copper bed-rails are having on hospitals in Chile and the US.

Copper Silver Challenges Illuminated in PPG Article

EPI Copper Silver Ionization - Legionella Control

Enrich Products was featured this weekend in a Pittsburgh Post-Gazette (PPG) article outlining the challenges copper silver ionization is still facing in the wake of the Pittsburgh VA outbreak over two years ago.

Writer Sean D. Hamill interviewed our President, Neil Silverberg and Chief of Operations, Aaron Marshall for the article and our own Erik Harker was photographed (using our new testing lab in our Pittsburgh headquarters) for the front page article.

You can read the full article on the PPG???s website here.

For over 25 years, Enrich Products has been, and continues to be committed to full regulatory compliance. We have??EPA registration and are??NSF/ANSI 61 and 372 Certified??to ensure we meet and exceed every standard.

Enrich??testified before Congress about the efficacy of copper silver ionization and, subsequently, the technology was found not to be at fault for the outbreak.

In spite of Enrich???s testimony, our willingness to cooperate with regulations, and the exoneration of copper silver ionization in the Pittsburgh VA outbreak, the Pennsylvania State DEP and Allegheny County are still setting public recommendations that copper silver ionization not be used in Pennsylvania facilities.

We are working with the PA DEP and other state administrators across the country to insure that the reliability and efficacy of ionization, as the preferred method of Legionella Control, is recognized.

If you are concerned about your state???s policies, would like us to speak to your state???s administrators, or simply want more information on copper silver ionization or Legionella control, please give the office a call toll-free at 1.800.369.7662 or send us an email.

Clearing the Air – Short Course Treatments

In an article about Legionella published on, Dr. Victor Yu (Special Pathogens Laboratory), stated the only company offering??short-term ionization treatments is LiquiTech. ??
This is in fact, ??an erroneous statement, and Dr. Yu has stated he will publish??a retraction.

Enrich Products Inc., was the first ionization company to begin using??short-term, or as we refer to them, “Short??Course” treatments. ??We introduced this application in 2007 as a response to the need expressed by our health care client to have a solution ( to a Legionella outbreak) immediately without incurring a large cost. ??Their primary need was for immediate results however, they were also concerned with seeing its efficacy before committing to a long term program.

Our??Short??Course??method requires diligent??monitoring, can significantly reduce Legionella in water quickly,??and copper silver levels needed for Legionella control can be achieved within hours.

Enrich Products has been a leader in Legionella control for over 17 years and is our systems are EPA registered. Our dedicated staff work as partners with facilities to control Legionella using the Best Available Technology, and can deliver an emergency??Short??Course??system within 24 hours.

CDC Director Testifies Before Subcommittee

CDC logo

???We missed the broader pattern.???

CDC Director Thomas Frieden acknowledged the CDC???s historically flawed reactive approach to handling anthrax and H5N1 bird flu last week before the subcommittee of the House Energy and Commerce Committee.

Their attitude on these bacteria is comparable to their approach with Legionella, which is solely reactive as well.

The CDC only recommends testing a building???s water for Legionella after an outbreak has occurred, a stance for which they have been highly criticized. Proactive testing could have prevented several outbreaks of Legionella across the country, manifesting in several fatalities in numerous states including Pennsylvania, Chicago, and Ohio. Legionella is not transferred person-to-person like other pneumonias and is exclusively contracted from environmental sources. ?? The bacteria can be found in almost every corner of the world and can grow in just about any type of building. Since its discovery in 1976, over 900,000 cases of Legionella have been documented.??For this reason, many experts have been highly critical of the CDC???s ???test-after??? approach, as testing a building???s water is the only way to determine if Legionella bacteria are present in the water.

Director Frieden is reviewing the CDC???s approach, and said at a press conference in regard to their past mishaps with other bacteria, ???Events like this should never happen, and that???s why I will do everything in my power to make sure that nothing like this happens again.???

Combined Effects of Copper and Silver Ions




1943 Benedum Hall, University of Pittsburgh, Pittsburgh, PA 15261, USA

2Veteran Affairs Medical Center, Pittsburgh, Pa 15240, USA

Abstract ??? Copper/silver ionization is a new disinfection method that is being used to eradicate Legionella pneumophila from the hospital hot water recirculating systems.?? The objective of this study was to determine the susceptibility of L. pneumophila serogroup 1 to copper and silver ions alone and in combination.?? L. pneumophila serogroup 1 (L.p. sg- 1) was completely inactivated (6-log reduction) at copper concentrations of 1 mg/l within 2.5 h, whereas more than 24 h was required to achieve a similar reduction at the highest silver ion concentration tested (0.08 mg/l).?? Checkerboard method and Gard additive model prediction demonstrated that copper and silver ions in combination could result in additive or synergistic effect depending on the concentration of copper and silver ions.?? Under the experimental conditions used in this study, synergism of copper/silver ions in eradicating was observed at higher concentration combinations of copper/silver ions (e.g. 0.4/0.04 mg/l) while only an additive effect was observed at lower concentrations combinations (e.g. 0.2/0.02 mg/l).?? This study suggested that both copper and silver ions are effective in inactivating L. pneumophila and the combined effect is greater than that seen with either ion alone.??
