30 May Why we say our antimicrobial labels are effective against 99.9% of all bacteria
Denny Bros’ antimicrobial labels help prevent the spread of harmful bacteria.
Here at Denny Bros we offer an antimicrobial label printing service that makes use of a specialist varnish that is effective against 99.9% of all bacteria.
The anti-bacterial properties of silver
The varnish contains additives derived from silver, long-known for its anti-bacterial properties, which is useful for companies looking for labelling solutions where hygiene is an important factor. These include businesses in food manufacturing or healthcare and pharmaceuticals.
Why 99.9% effective?
But, why do we say our antimicrobial labels are effective against 99.9% of all bacteria? Why is this figure often used when talking about other anti-bacterial products such as domestic bleach or surface cleaners? Why not 100%?
There are two reasons why this figure is used.
Firstly, bacteria is able to develop resistance to most anti-bacterial agents, so if a large enough sample of bacteria is examined, there is a chance that observers might find a very small fraction, which are resistant. So, when manufacturers use the 99.9% figure, they are acknowledging this dynamic.
The second reason is that science does not work with absolute certainties. Despite rigorous testing of samples, there is no unequivocal way of definitely knowing that 100% of all bacteria is wiped out by a particular agent. Thus the 99.9% figure is used.
A major use of antimicrobial labels is for medicine and equipment used in hospitals and health centres, where so-called healthcare-associated infections (HCAIs) are an issue. HCAIs, such as MRSA, Clostridium difficile and Noroviruses, can be carried both on people and equipment, so it is important to take every possible step to mitigate the chances of transferring any bacteria from containers and packaging to medical staff or directly to patients.
HCAIs are a particular focus for hospitals because it is estimated that 9% of all inpatients have an infection associated with their care in hospital.
