 Salmonella enterica is a common cause of salmonellosis, a zoonotic disease that can affect both animals and humans. It is often transmitted through contaminated food or water sources, and can also be spread by contact with infected animals or their environments. In this study, researchers examined the effectiveness of two commonly used disinfectants, gluteraldehyde and parasitic acid, on salmonella biofilms found in pig housing facilities in the UK. They found that both disinfectants were effective in reducing the number of salmonella cells by four logs when applied at a concentration of 0.05%. Additionally, they observed that the disinfectants were more effective than previously reported results obtained from other tests conducted on planktonic bacteria. This suggests that biofilms require higher concentrations of disinfectant to effectively reduce the number of cells present.
