A limitation of estimating dietary exposure over a period of time associated with the dietary modelling is that only 24-hour dietary survey data were available, and these tend to over-estimate habitual food consumption amounts for high consumers.
Molluscs and crustacea are occasionally consumed foods that people tend to consume less than once a week. Therefore, consumption figures derived from a 24-hour recall may be higher for most consumers than if consumption amounts were averaged over a longer time frame that better reflects habitual consumption of these foods. Other limitations of the dietary modelling include:
smoked finfish was not identified as being hot- or cold-smoked in the National Nutrition Survey
scallops are not identified as being roe-off or not.
