Research hails chlorine dioxide gas potential to combat Listeria threat on RTE meat processing kit
Chlorine dioxide (CIO2) gas has the capacity to completely inactivate Listeria monocytogenes (LM) on ready-to-eat (RTE) meat processing equipment, according to new research.
Biofilms and sanitization
While sanitization is commonly carried out in processing plants, their effectiveness can be affected by a wide range of factors including the ability of bacteria to form protective shields known as biofilms.
The study identifies a raft of sanitizing agents, including CIO2 but said the latter is usually employed in liquid rather than gas form.
The team examined the effect of CIO2 on biofilm and non-biofilm (planktonic) LM samples. It used five strains of the pathogen – FSL 103-M, FSL N1-227, Scott A and one strain of innocua, for the planktonic cells as well as monocytogenes 311 and 82, for the biofilms.[/I]
