In accounting for these factors, an extensive description of uncertainties in the risk estimate and their origins should be provided, as well as, descriptions of how assumptions being made can increase or decrease the uncertainty of results in the risk assessment. To increase the validity of a risk assessment, it is recommended that the assessment remain open for peer review and editing by food safety and science communities. A proper risk assessment is a constantly revolving process consisting of the following steps: (i) hazard identification, (ii) hazard characterization, (iii) exposure assessment, and (iv) risk characterization.[5]
