Applying pesticides to livestock, particularly sheep dipping, is a source of occupational pesticide exposure on livestock farms but there are relatively few published data about worker exposures during this task. Published data from the UK suggest that like other applicators, skin absorption is the main route of exposure during sheep dipping and particularly associated with handling of concentrates, and to a lesser extent splashing with dilute dip as animals pass through the bath. Inhalation does not appear to be an important route of exposure. Given that dip baths need to be regularly topped up with concentrate, handling is frequent and the potential for skin contamination among those workers who handle the concentrate is high
