Since 2003 the (German) Drinking Water Directive stipulates that central hot water systems have to be tested for the microbiological parameter Legionella spec. No more than 100 colony-forming units (100 CFU) of those bacteria should be present in 100 ml of drinking water; otherwise further (technical) measures to reduce the contamination are mandatory. But what exactly are Legionella?

BBA Drinking Water Seminar with Laboratory Tour and “Live” Legionella Culturing on June 6th in Berlin.

Many companies are about to undergo their third major round of routine drinking water testing for Legionella in their building stock. As in previous intervals, the conditions have once again changed. Therefore, on June 6, 2019, the Berlin-Brandenburg Academy of Housing Economy (BBA) will host a seminar in Berlin that provides training on new and current regulations and requirements of the Drinking Water Ordinance. A special highlight of the event is the live demonstration of a Legionella analysis in the laboratory at the end of the seminar.

125 years institute for hygiene und public health of the university Bonn

On Friday, September 20th, 2019, the 125th anniversary of the institute for hygiene and public health (ihph) was celebrated in the university club Bonn. All speeches were held not only by excellent experts of medicine and hygiene but by extraordinary capacities in public health research and science. The specialists all agreed in one point: to meet future challenges it will not be enough to gather and apply expert know-how, it needs meta competence as a key factor for every expert to attain good results in the tasks the "global village" presents. Honored was Prof. Dr. med Martin Exner who has presided the institute for more than 25 years for his outstanding achievements in the public health sector - not only in Germany but worldwide.
