On industrial river catchments regular flooding is associated with higher PCDD/Fs and PCBs levels in soils and grass. This contamination may be transferred to food but the impact varied by food type. These contrasts may be due to physiological differences between animals, the ages at which they are sent to market and differences in animal husbandry.
To minimise the risks of producing food on flood-prone land in catchments with a history of industrialisation, as well as on any land with elevated PCDD/F and PCB levels this research suggests a number of options. The choice of livestock may be important and as an example in our study beef cattle appeared to accumulate PCDD/Fs to a higher degree than sheep. Land management may also play a role and could include minimising the time that livestock spend on such land or feeding commercial feed, low in PCDD/Fs and PCBs, where appropriate.
