aMean ± SD, n = 5; values in the same column for each attributes followed by a different letter (a–d) are significantly different (). AEO: acidic electrolyzed oxidizing (AEO) water (100 mg/kg) treatment for 5 min. AEO washed: acidic electrolyzed oxidizing water treatment for 5 min followed by washing. AEO + L: electrolyzed oxidizing water treatment for 5 min followed by spraying of 0.5% lysozyme enzyme (L) solution. AEO washed + L: electrolyzed oxidizing water treatment for 5 min followed by washing and spraying of 0.5% lysozyme enzyme solution on the total viable count of carp samples.
