HUAZHANG, L et al. Detection of shellfish toxins from scallops in Guangzhou seafood market. J. Venom. Anim. Toxins incl. Trop. Dis [online]. 2011, vol.17, n.1, pp. 74-84. ISSN 1678-9199. http://dx.doi.org/10.1590/S1678-91992011000100010.
To evaluate scallop safety in the Guangzhou seafood market, contents of shellfish toxins in adductor muscle, mantle skirts, gills and visceral mass of scallops were examined using enzyme-linked immunosorbent assay (ELISA) and mouse unit assay. The results showed that: paralytic shellfish poisoning contents were up to 37.44 μg/100 g by ELISA and 319.99 MU/100 g by mouse unit assay, which did not exceed the limits of national standards (80 μg/100g and 400 MU/100 g); the contents of diarrhetic shellfish poisoning were 142.04 μg/100g and 0.2 MU/100 g, which exceeded the national standard limits (60 μg/100g); neurotoxic shellfish poisoning was undetectable; the contents of amnesic shellfish poisoning reached 220.12 μg/100g (no limit value could be referred to) . In addition, these poisons were present mainly in visceral mass and gills rather than adductor muscle and mantle skirts, suggesting that these toxins accumulate in a tissue-specific manner.
