Your Risk Assessment must be reviewed at least every two years, earlier if:
if there is any change in the fabric or use of water systems
if an outbreak of the disease occurs
if there is any reason to believe it may no longer be valid
It is an imperative aspect of prevention and control and will ensure you are keeping up to date with legislative changes and also changes on your site. It is pro-active and preventative.
