Conclusions
We have demonstrated here that Whitaker’s method is applicable to phycotoxins in
shellfish. To our knowledge, this is the first time that a probabilistic evaluation of
sampling plan designs for phycotoxins in shellfish has been undertaken. Sampling
plan designs are of the utmost importance when determining, in a trustworthy way,
the human health status of a particular shellfish growing area. This method has been
validated on variance data that we had at our disposal, but it needs to be validated
on further data. It is suggested that a Food Sanitary Agency, involved in phycotoxin
monitoring, test this method on a larger data set.
