Growth evaluation. We found that the number of colonies formed per each plate (non-selective medium) until the second day after HPP was less than LOQ (limit of quantification, i.e., the lower limit of acceptably accurate cell counts). Therefore, we concluded that no significant growth happened during the first two days after treatment. LOD (limit of detection) and LOQ in our plating method were 1.00 and 2.40 log CFU/ml, respectively
