Deriving “potential target values” of PCDD/F in animal feed: the role of livestock at the interface between feed and food chain

Abstract Linking derivation of potential target values PCDD/Fs in animal feed with risk assessment for consumer protection is a challenge when tolerable weekly intake (TWI) and transfer factors from to food are considered. Generally, maximum set separately without considering the producing as an important factor along chain farm fork. Levels contaminants can accumulate animals their products effect consumers at end chain. Hence, process setting legal levels should account consumed by into human consumption. Here, we calculated PCDD/F ensure that such milk dairy cows, eggs laying hens pork fattening pigs safe In our approach, using PCDD/F-TEQs fat, fat products, taking derived European Food Safety Authority. We assumed equal proportions WHO-PCDD/F-TEQ WHO-PCB-TEQ feed. Potential expressed quantity toxicologically evaluated PCDD/Fs, WHO toxic equivalents (WHO 2005 -PCDD/F-TEQ) per kg 12% moisture. current would be 10–54 times lower than level 0.75 ng -PCDD/F-TEQ (12% moisture), according Directive 2002/32/EC amended.
