Research – Salt can help fight superbugs, new research and 3D printing could create new industry


Salt could soon be more than just a seasoning with new Canadian research discovering its potential to fight superbugs.

Published in Volume 94, Issue 2 of The Journal of Hospital Infection, the study found that a superbug strain called Methicillin-resistant Staphylococcus aureus (MRSA), will only survive on salt for five minutes.

Comparatively, copper, which is often considered a surface in-which disease-carrying bugs do not live long on, was also tested but the MRSA strain lasted 90 minutes on the surface.

Stainless steel performed even worse with the MRSA superbug living for over six hours on the surface.

The research is now being used to help create a line of products which compress salt together to make coverings that can be placed on door handles in an effort to fight off the spread of disease.
