It is of the utmost importance to manage legionella because, if it is allowed to continue poisoning water supplies, it may cause irreparable harm to the lungs over time. Keeping this in mind, this is also the area in which legionella control has become more crucial in more recent times, as well as the explanation for this. In the event that legionella bacteria proliferate to the point where larger numbers are discovered in the source water, the likelihood of this happening rises. Generally speaking, the circumstances that are favorable for the proliferation of legionella bacteria into bigger numbers are not present in fresh water sources (which is why the number of bacteria in natural water is low). The bacteria are able to endure temperatures ranging from 20 to 50 degrees Celsius, but they thrive and grow in water that has a temperature of 35 degrees Celsius as their ideal living and growing temperature. This is the reason why any system that uses hot or cold water has to be properly maintained in order to avoid the kinds of circumstances that would be ideal for the growth of legionella, which would result in an increased likelihood of someone having legionnaires’ disease. There are a number of places where legionella may be discovered, including but not limited to: cooling towers, evaporative condensers, air conditioning, spas and whirlpools, humidifiers, and hot and cold water systems. During the 1970s, the United States of America saw a significant epidemic of pneumonia, which led to the discovery of legionnaires’ disease. It is the species of the legionella bacterium known as l. pneumophila that is responsible for the development of legionnaires’ disease. Pontiac fever is yet another less severe ailment that is often considered to be connected with the bacterium. It is believed that the number of cases of legionnaires’ disease that are recorded each year in England is far lower than the actual number of cases that are reported. On the other hand, this does not include instances that have been documented in which the individual was exposed to legionella bacteria at a location other than England. In this day and age, legionella control services are unquestionably something that cannot be disregarded in terms of the position that they play and the overall significance that they have. It is also a growing field, and more and more people are being employed for the service that it provides. If you are in charge of the health and safety of a building, it is of the utmost importance that you exercise control over the water supply and system in order to stop the proliferation of legionella. Performing a comprehensive risk assessment of your water system is the first step in accomplishing this goal. By doing so, you will be able to identify any possible problems that you could be experiencing with your water system. This will allow you to devise a management strategy to handle these problems and ensure that they do not become a danger of legionnaires’ disease. When it comes to the overall management of the risk of legionella, this is also a significant issue worth considering.
