Description	Multi-hollow surface dielectric barrier discharge (MSDBD) generating plasma-activated gaseous media was used to decontaminate fresh raspberries inoculated with Enterococcus faecium bacteria. The highest microbial inactivation of 2 log10 was achieved for the exposure time of 1 min, distance of 10 mm and flow rate of 15 L/min. No colour changes on raspberries were observed after the plasma decontamination process. Temperature monitoring of the raspberries' surface immediately after plasma treatment showed only a slight increase, therefore giving positive implications for the product quality.
