Mean ± standard deviation	224.91 ± 114.67/152.73 ± 94.37/279.91 ± 183.66/657.55 ± 368.46	0.73 ± 1.01/0.45 ± 0.69/0.55 ± 1.04/1.73 ± 1.90

Microbial contamination of the surface of the tablet was significantly lower than the contamination of the outside of the used plastic bags (ROI A, B and C; ROI A + ROI B + ROI C; p < 0.001). ROI  =  Region of interest.
