Tolerance residue limits are often considered as inadequate for human health protection when adopted at their face values. Underlying this allegation is the fact that the consumption rate used for tolerance derivation is often insufficient for at least some localities. For example, average fish consumption rates reported by Gillett and Lightfoot (2002) were up to 567 g/day per capita for people in Kiribati, which is 38 times greater than that (15 g/day) reported by Nylander (2004) for people in Finland. The average per capita rate for Pacific Island countries is around 200 g/day (Gillet and Lightfoot, 2002), whereas the worldwide average is close to 44 g/day (FAO, 2004). Note that by definition the fish intake for consumers in a locality will be greater than that locality’s per capita rate.
