The beta-Poisson dose-response model (Eq. 7) was applied to
estimate the probability of illness (Pill) per meal as proposed by
the U.S. FDA (2005). Ppat is the prevalence of the pathogenic V.
parahaemolyticus as described in Section 2.2.1.1.
Pill = 1 − (1 + Dmeal/β)
−αxPpat (7)
Apparently, we do not have the dose-response parameters for
Malaysian, thus, we adopted the dose-response values presented
by the U.S. FDA (2005); at each iteration of our simulation, a combination
of parameters was selected with the probability corresponding
to the likelihood shown in the FDA report.
