P95: 95th percentile; DL‐PCB: dioxin‐like polychlorinated biphenyl; PCDD/F: polychlorinated dibenzo‐p‐dioxin and dibenzofuran; TEQ: toxic equivalents.

^aThe 95th percentile estimates obtained with less than 60 observations may not be statistically robust (EFSA, 2011a). Those estimates were not included in this table.
