Author: Environment Agency Wales
Document Type: Monograph
This Environment Agency report describes the Welsh sheep dip monitoring programme in 1998. Sheep are prone to infestation by a number of ectoparasites and are dipped for economic, cosmetic and welfare reasons. Sheep Scab, caused by the ectoparasites Psoroptes ovis or Sarcopies scabiei, is perhaps the most serious condition which can cause discomfort and even death. There is therefore a need for effective treatment systems on sheep welfare grounds. Two groups of chemicals are currently licensed for sheep dipping: organophosphates (OPs) and the newer synthetic pyrethroids (SPs) such as flumethrin and cypermethrin. Since 1995 there has been an increasing awareness of the environmental problems associated with the use of synthetic pyrethroid based sheep dips. Given the importance and prevalence of sheep farming within Environment Agency Wales and the Midland Region of the Environment Agency, a monitoring programme was initiated for the 1997 dipping season in order to 'Determine whether there is evidence of widespread environmental impact from sheep dipping activities, especially from the use of synthetic pyrethroid dip.
