The test procedure yielded reproducible data on different days and across different technicians
^aThe values shown are the percent decrease in viable bacteria recovered from the cold-pressed hemp seed oil or full-spectrum hemp extract samples, as compared to the viable bacteria recovered from the paired acetate-only samples run on the same day. All samples were on aluminum foil backing of the same type and thickness
