Disinfection
POLAND
The first group of specimens was placed in a UV light chamber for an exposure time of 2.5 min (150 s). The germicidal disinfection cabinet (MADA, Model No.: MA20-16W) was designed and manufactured in United Arab Emirates, UAE, and assembled in China. The device is equipped with four germicidal lamps (Philips, Poland) with a wavelength of 253.7 nm and an intensity of 1024 μW/cmThe second group (positive control) was disinfected using Zeta 7 spray (Zhermack, Italy). The solution is composed of 83 g ethanol, 10 g 2-propanol, non-ionic surfactants, additives, auxiliaries, and water to 100 g, with a distance of 10 cm to ensure maximum coverage/exposure. They were then allowed to evaporate for 3 min. The third group received no treatment and acted as a negative control. The experiment was repeated three times to ensure the reproducibility of the results.
