risk of consumption of these larger-sized species of fish by pregnant women is not<br />
publicized <strong>in</strong> Fiji so a def<strong>in</strong>ite health risk exists. Canned fish can be consumed <strong>in</strong><br />
moderate quantities (4-7 cans per week depend<strong>in</strong>g on body weight) without a risk of<br />
health effects (Fig. 4c) <strong>and</strong> shellfish <strong>and</strong> reef could be consumed <strong>in</strong> very large amounts<br />
(2-3 kg/week for an average sized person, Fig 4d).<br />
The analyses <strong>in</strong> the current study were performed on raw (uncooked) fish tissue but<br />
mercury is not significantly removed by normal cook<strong>in</strong>g processes (USEPA, 2001).<br />
Because moisture is lost dur<strong>in</strong>g cook<strong>in</strong>g, the concentration of mercury (on a weight for<br />
weight basis) after cook<strong>in</strong>g is actually higher than it is <strong>in</strong> fresh uncooked fish (USEPA,<br />
2001).<br />
Figure 5: Fish price list <strong>in</strong> Suva, Fiji show<strong>in</strong>g the low price for a number of<br />
species which conta<strong>in</strong> high mercury levels.
