"The large scale of this algal bloom and the high levels of toxin in tested shellfish mean the risk of shellfish poisoning from eating shellfish collected from the wild is very real".
These samples are typically taken from shellfish collected along the shore, so no information is obtained about the algae themselves that may be present in near- or offshore waters.
Arsenic species data from the shellfish collected for this study (Table 1) and for three other clam species consumed (geoduck, mussels, and razor clam) were used to derive an estimated intake of As+3, As+5, DMA, and MMA (Table 4).
This method was successfully applied to determine DA levels in 46 shellfish samples collected from Valencian (Spain) supermarkets, showing high sample throughput.
The hybrid technique was applied for the speciation analysis of mercury in three certified reference materials, 14 fish, and shellfish samples collected from local markets.
Within the ECsafeSEAFOOD FP7 project, a wide variety of emerging contaminants including brominated flame retardants, pharmaceuticals, perfluoroalkyl substances, musk fragrances, polycyclic aromatic hydrocarbons, UV-filters and endocrine disruptors, as well as inorganic arsenic and methylmercury, were analyzed in fish and shellfish samples collected all over the European Union.
During summer 2005, seawater temperatures ≈19°C were recorded in several places along the coast of Region X where shellfish are collected (7 ).
During this pilot study, shellfish were collected for toxin analysis when Dinophysis light microscopy counts exceeded 3,000 cells/L for >2 consecutive weeks.
The park and commercial site remained closed until 2 consecutive shellfish samples collected 7 10 days apart demonstrated total DSP toxin levels <16 µg/100 g.
On December 8, the three states issued a joint press release saying that fish and shellfish samples collected and analyzed since the hurricanes "show no reason for concern about the consumption of Gulf seafood".
