Treatment of data below LOD–LOQ are not described; it is extremely likely that mean contents are expressed on positive samples. LOQ: NDMA = 0.15 μg/kg, NDEA = 0.07 μg/kg; NDMA content ranged from < 10 to 4.0 μg/kg and NDEA content from < 0.07 to 2.7 μg/kg.
Mean calculated from all samples analysed, < LOQ set to LOQ, non‐detectable set to 0. LOD = < 1 μg/kg. NDMA content ranged from non‐detectable to 4 μg/kg and NDEA content ranged from non‐detectable to 0.3 μg/kg.
Estimated by the Panel assuming the middle bound scenario, LOD(Q) = LOD(Q)/2; LOD NDMA = 0.48 μg/kg; LOD NDEA = 0.52 μg/kg. NDMA content ranged from non‐detectable to 5.7 μg/kg and NDEA content ranged from non‐detectable to 3.6 μg/kg.
Sum of the mean content level of NDMA + NDEA calculated by the Panel.
