Tristel top of the class after French study

Tristel plc, the AIM-quoted manufacturer of infection prevention, contamination control and hygiene products, is basking in the outcome of a major study.

The study conducted at the Centre Hospitalier Régional Universitaire de Lille, France, compared its Trio Wipes system with a detergent and a peracetic acid disinfectant manufactured by Laboratoires Anios, Hellemmes, France.  Anios is France’s leading infection prevention company and has recently been acquired by Ecolab Inc. of the United States.

The study found that the wiping procedure with Tristel’s chlorine dioxide chemistry displayed more than a five-log reduction of four strains of bacteria in 30 seconds and a four-log reduction of bacterial spores in two minutes.

The soaking procedure with peracetic acid displayed similar results as chlorine dioxide against bacteria but took 10 minutes to do so and was unable to achieve a 4-log reduction in bacterial spores.

Bacterial spores are considered to be the most resistant organisms to disinfectants and the ability to kill them both in high numbers and quickly is the distinguishing feature of the highest performing products.

Peracetic acid is the most widely used high-level disinfectant throughout Europe and soaking an instrument, rather than wiping it, is considered to be the traditional method to disinfect a medical device.

The medical device used in the study was a flexible nasendoscope used in Ear, Nose and Throat departments. ENT is one of Tristel’s main niche markets within hospitals. The study has been published in the Journal of Infection Prevention.

The Tristel Wipes system is regarded as a unique, patented decontamination method for non-lumened scopes and probes. It has been a very significant sales success for the company globally. Worldwide sales of the system in the financial year ending June 2016 were £8.7 million.

CEO Paul Swinney (pictured above) said: “We are pleased to see the publication in a peer-reviewed journal of this significant study comparing our Wipes system with peracetic acid, which is the most widely used high-level disinfectant chemistry in Europe and probably the United States also.

“The results affirm the key advantages of our wipes over alternative chemistries and disinfection methods. These advantages are the level and speed of kill of the most resistant organisms.

“This is the 26th peer-reviewed and published scientific paper featuring Tristel products – a body of evidence of our products’ attributes that forms one of our company’s key strengths.

“France is one of our key target markets for growth and this study can only help with this ambition.  We sell our products through a distributor in France.”
