Mean levels of PCDD/Fs (lower bound) in milk and eggs after feeding cows (n = 3) for 33 days and laying hens (n = 5) for 56 days with contaminated feed followed by a similar period on clean feed (modified from Hoogenboom et al., 2006, 2015c). Cows obtained maize silage contaminated by a fire (0.79 ng WHO ₂₀₀₅‐TEQ/kg; 17 kg feed/day), laying hens feed contaminated with a standard mixture (0.40 ng WHO ₁₉₉₈‐TEQ/kg, 0.11 kg feed/day)
