Vetnews | Oktober 2024 22 « BACK TO CONTENTS Each swab was collected, activated and measured (within 30 seconds), in accordance with the manufacturer’s instructions. All swabs were collected and read by the author, in order to minimise the risk of false variability. The outcome of each swab was the quantifiable numerical result produced by the handheld Hygiena Ensure Luminator, ATP reader. The cleaning at all sites involved the removal of biofilms, using a proprietary agent (F919, Health and Hygiene (Pty) Ltd), and the provision of brush attachments for use on DIY hand drills to assist in the cleaning of challenging surfaces and areas. Biofilm removal was repeated several times initially and thereafter prior to each deep clean (weekly or monthly depending upon usage) Cleaning was then undertaken with a safety and efficacy certified, recognised veterinary disinfectant cleaner (F10SCXD, Health and Hygiene (Pty) Ltd), completed with a final, safety and efficacy certified recognised veterinary disinfectant (F10SC, Health and Hygiene (Pty) Ltd), for use by fogging (whilst patients and staff are present). All chemicals were applied in accordance with the manufacturer’s instructions. This cleaning and sanitisation process was applied at each site, firstly because it is considered by the author to be an optimal process, but so as to standardise the cleaning procedure, thereby removing a further variable. The cleaning protocol was explained verbally, and in writing to the hygiene supervisor at each site. Tests were only conducted on Tuesday (except where a Tuesday was the first working day after a bank holiday), Wednesday, Thursday or Friday mornings, i.e. avoiding mornings when there may not have been effective cleaning at the end of the previous day (weekends and bank holidays). On the morning of each test, the hygiene supervisor was asked if any untoward event had occurred in the proceeding 24 hours, that might be anticipated to give rise to abnormal test results, the author was not made aware of any such events. In respect of fomite site collection, the swab sites were by definition preset, e.g. x-ray switches, anaesthetic controls, light switches, keyboards, and kennel doors, as such it was considered that selection bias was not relevant.
