Summary
Abstract
Aims: To evaluate the efficacy of electrolysed NaCl solutions (EW) for disinfecting bacterial isolates from carp, and the potential application of EW to reducing the bacterial load in whole carp and carp fillets. Methods and Results: EW was produced by using a two-compartment batch-type electrolysed apparatus. Pure cultures (in vitro), whole carp (skin surface) and carp fillets were treated with EW to detect its antimicrobial effects. The anodic solution [EW (+)] completely inhibited growth of the isolates. Furthermore, dipping the fish samples in EW (+) reduced the mean total count of aerobic bacteria on the skin of whole carp and in fillets by 2 8 and 2 0 log10, respectively. The cathodic solution [EW ( )] also reduced growth of the isolates from carp by ca 1 0 log10. Moreover, the total counts of aerobic bacteria in whole carp (on the skin) and fillets were reduced by 1 28 and 0 82 log10, respectively. Conclusions: EW (+) has a strong bactericidal effect on bacteria isolated from carp. Significance and Impact of the Study: Treatment with EW (+) could extend the shelf life of these fish.

Reading this responsibly
Published figures are obtained under controlled conditions, usually on clean surfaces or in defined matrices. Organic load, surface condition, temperature and application coverage all affect real-world performance. Use these numbers to design a protocol, then validate it on your own site with environmental swabbing.
Applying it
Concentrations in this range are within the adjustable output of every EcoloxTech commercial system, so implementing this protocol is a settings question rather than a procurement one. Where the claim needs to sit on a registered label, see HOCl-AS200, EPA Reg. No. 101112-1.
