Controlling Legionella in Hospital Water Systems: Experience With the Superheat-and-Flush Method and Copper-Silver Ionization
JANET E. STOUT, YU-SEN E. LIN, ANGELLA M. GOETZ, ROBERT R. MUDERCAMBRIDGE UNIVERSITY PRESS, INFECTION CONTROL AND HOSPITAL EPIDEMIOLOGY, DECEMBER 1998 IntroductionThis study evaluated the efficacy of superheat-and-flush and copper-silver ionization for Legionella control in an acute care hospital. The hospital had been using the superheat-and-flush method for 13 years but was still experiencing incidences of […]
Controlling Legionella pneumophila in Water Systems at Reduced Hot Water Temperatures with Copper and Silver Ionization
ELAINE CLOUTMAN-GREEN, VERA L BARBOSA, DIEGO JIMENEZ, DANIEL WONG, HELEN DUNN, BRIAN NEEDHAM, LENA CIRIC, JOHN C HARTLEYELSEVIER, AMERICAN JOURNAL OF INFECTION CONTROL, JANUARY 2019 IntroductionThis study was conducted at a newly built healthcare facility in the United Kingdom. There, the Department of Health recommends maintaining hot water temperatures above 131o F (55o C) to control Legionella in water […]
Use of Copper-Silver Ionization for the Control of Legionella in Alkaline Environments at Healthcare Facilities
DAVID M. DZIEWULSKI, ERIN INGLES, NECULAI CODRU, JOHN STREPELIS, DIANNA SCHOONMAKER-BOPPELSEVIER, AMERICAN JOURNAL OF INFECTION CONTROL, JULY 2015 IntroductionThis study examined two healthcare facilities using copper-silver ionization to control Legionella in alkaline water conditions. One facility was an acute care facility with a pH range of 8.7-9.9. The other was a long-term care facility with a pH […]
Why Legionella Testing is Essential for Building Owners
An essential part of building ownership is ensuring your drinking water is safe. This includes having an active water management program and conducting regular testing for Legionella bacteria. What is Legionella? Legionella is a type of bacteria that can grow in your building’s water system. Legionella is pathogenic, meaning that exposure to it can cause disease. It […]
News Release: New Study Shows Copper-Silver Ionization is Effective for Legionella Control
Legionnaires’ disease cases have increased nearly tenfold in recent decades, leading to thousands of hospitalizations and deaths. Outbreaks are linked to Legionella, a bacteria found in potable water systems in large facilities like hospitals, multi-family buildings, resorts, and office buildings. A recently published study shows that copper-silver ionization effectively controls Legionella in building water systems […]
Ten Causes of Legionella in a Building’s Water Supply
Water from municipal water systems is often contaminated with small amounts of bacteria, parasites, fungi, and other organisms that escape disinfection methods. The low amounts of these organisms generally do not cause disease but can pose a threat in complex or multi-story plumbing systems due to various factors. Here are the most common. Water temperature […]
Five Practices to Prevent a Legionella Outbreak and Control Waterborne Pathogens
The Centers for Disease Control and Prevention (CDC) has reported between 8,000 and 18,000 cases of Legionnaires’ disease annually in the United States caused by the spread of the Legionella bacteria. How can you protect your facility from Legionella and other waterborne pathogens? Here are five practices that you can implement to prevent bacterial outbreaks in your […]
Strategies For Protecting Your Hospital From Legionella Growth
Legionnaires’ disease, a deadly but preventable form of pneumonia, is a risk in healthcare facilities across the country. The Legionella bacterium causes this infection and is found naturally in fresh, warm water sources. However, it can increase in the plumbing of large buildings such as hospitals. For this to happen, Legionella must first grow and then spread […]
Controlling Legionella Using Copper Silver Ionization
Hospitals and healthcare facilities need to do everything possible to prevent contagious diseases from spreading. One of the most critical ways they can do this is by providing water that has been treated to kill harmful pathogens such as bacteria and viruses. However, there are other environments in which clean water is an absolute necessity. […]
