Bactericidal activities of a wet disinfectant mat in a food factory

摘要

The antibacterial activity of the agent of a wet disinfectant mat (WDM) utilizing benzalkonium chloride (BAC) and sodium carbonate was researched. The agent of the WDM showed a bactericidal activity in which there was a decrease of 10~7 cfu/ml or more in all the strains tested in an exposure of 30 s or more. On the WDM, Staphylococcus aureus showed blebs after 30 min, and remarkable destruction of bacterial body was also observed. After 2.5 h on the WDM, the whole bacterial body of Salmonella enteritidis was covered with many irregular blebs. In the early stage at 5 min after pouring the bacterial suspension on the WDM, embedding of S. enteritidis in the drug layer was observed. These results suggested that the WDM would trap and kill microorganisms in food factories.
