Single-day validation results obtained for the analysis of lipophilic marine biotoxins in shellfish (mussel) at the levels proposed by the European Food Safety Authority (n = 7) ^a

		Fortification level µg kg-1	Accuracy %	RSDr %	CCα µg kg-1	Rb
OA	Without SPE	22.5	96	10.1	53.3	0.998–1.000
		45	113	6.1
		67.5	108	5.4
AZA1	With SPE	16	107	2.1	34.5	0.999–1.000
		32	106	2.7
		48	104	1.2

^a The validation was conducted before the document for the AZAs was published. The proposed permitted level for AZA (30 µg kg^-1) slightly differs from the level chosen in this study (32 µg kg^-1).
