Title: Welsh sheep dip monitoring programme : 1998 - March 1999
Author: Environment Agency Wales
Document Type: Monograph
This Environment Agency report describes the sheep dip monitoring programme held in 1998 in Wales. 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. The monitoring programme for 1998 was set up with the following two main aims: to establish whether the results of the 1997 survey were representative of a larger proportion of upland Wales; and to use chemical and biological monitoring to target pollution prevention activities in catchments believed to be at risk.
