At Shimonoseki Marine Science Museum, there is no record except for one case as described in detail below of outbreak of Erysipelas infection about 18 years since establishment of our facility in 2001. The case out of 20 individuals of our Cetacean collection (12 Bottlenose Dolphin and 8 Finless Porpoise), Erysipelothrix rhusiopathiae was isolated from one of Finless Porpoise blood sample. The antibody titers against E. rhusiopathiae of Growth Agglutination (GA) of 12 individuals in April 2018 were all less than 16 times. On the other hand, gene fragments specific to E. rhusiopathiae were detected from our frozen foods for marine mammals which was in use as of February 2018. We have been using Neutral PH Electrolyzed Water through storing these food items in refrigerator after thawing, and these results indicate the possibility of suppression for bacterial growth by Neutral PH Electrolyzed Water on E. rhusiopathiae.
