I have done some technical experiments in the past but nothing truly
scientific. I could not find any defined benefits in terms of shelf life
extension even at the wash water ozonation level far in excess any limits in
potable water. After prolonged exposure of the fillets there was some shift
within bacteria flora and even some molds appeared but no practical quality
improvement in terms of obtaining sensoricaly sound product were ever
achieved. But the focus was on spoilage bacteria and not pathogens though.

In other words, most food technologists in the United States recognize
ozone's positive attributes but the necessary regulations have been slow to
develop.
