F1 Schs. 1A-1C inserted (31.12.2022) by The Food and Feed (Miscellaneous Amendments) (Wales) (EU Exit) Regulations 2022 (S.I. 2022/1362), reg. 1, Sch. 3

Table 1 (part 1)

Dioxins and polychlorinated biphenyls (PCBs)

Undesirable substances	Products intended for animal feed	Action threshold in ng WHO-PCDD/F TEQ/kg (ppt)(1) relative to a feedingstuff with a moisture content of 12%	Comments and additional information (e.g. nature of investigations to be performed)
(1) Upper-bound concentrations; upper-bound concentrations are calculated on the assumption that all values of the different congeners below the limit of quantification are equal to the limit of quantification.
(2) See Table 1 (part 2) for TEFs (= toxic equivalency factors) for dioxins, furans and dioxin-like polychlorinated biphenyls (PCBs): WHO-TEFs for human risk assessment based on the conclusions of the World Health Organisation (WHO) – International Programme on Chemical Safety (IPCS) expert meeting which was held in Geneva in June 2005 (Martin van den Berg et al., The 2005 World Health Organisation Re-evaluation of Human and Mammalian Toxic Equivalency Factors for Dioxins and Dioxin-like Compounds. Toxicological Sciences 93(2), 223–241 (2006)).
(3) Identification of source of contamination. Once source is identified, take appropriate measures, where possible, to reduce or eliminate source of contamination.
(4) In many cases it might not be necessary to perform an investigation into the source of contamination as the background level in some areas is close to or above the action level. However, in cases where the action level is exceeded, all information, such as sampling period, geographical origin, fish species etc., must be recorded with a view to future measures to manage the presence of dioxins and dioxin-like compounds in these materials for animal nutrition.
