| Abstract: | Strains of Staphylococcus aureus which colonize defeathering machinery and become endemic within poultry processing plants appear to be resistant to the normal cleaning and disinfection processes. The resistance of endemic strains to chlorine was compared with that of isolates from the natural skin flora of poultry. Endemic strains were almost eight times more resistant and this was due primarily to their ability to grow in macroclumps but also to the production of an extracellular slime layer. |
