Report: LS24-00208
Tests were carried out in a specialized laboratory in Switzerland in accordance with the norms and standards of the European Union, standard EN 1276 : 2019. Test for the evaluation of bactericidal activity of chemical disinfectants and antiseptics used in food, industrial, domestic and institutional areas. Research Conducted by the Swiss company Microbe Investigations AG, which is associated with the ETH Laboratory of Food Microbiology, which is engaged in fundamental research to develop new, advanced methods for the detection and control of bacterial pathogens.
Microbe Investigations AG is a subsidiary of the Swiss Federal Institute of Technology in Zurich. It was founded in 2012 as a result of an ETH opinion from the Institute of Food, Nutrition and Health of the Faculty of Health Sciences and Technology of ETH Zürich.
