Growth reduction of E. coli on tomato treated with different concentrations of gaseous ClO2. Tomato fruits were treated with 1 μg, 5 μg, or 10 μg ClO2 per gram of ripe berries. Upper-case letters indicate significant difference (P < 0.05) caused by ClO2 doses at the same time point. Lower-case letters indicate significant difference (P < 0.05) caused by time of exposure under the same ClO2 dosage.
