Occurence of Chlorfenvinphos Residues in Cow's Milk sampled at a Range of Sites in Western Kenya

The use of acaricide Chlorfenvinphos to control ticks and tick-transmitted diseases in cattle, causes in Kenya annually about 700 deaths and more than 300.000 poisoning cases. The latter figure can probably be even much higher as early symptoms are very similar to those of malaria.
Therefore, Evans Kituyi conducted research on the pesticide contents of milk and fat in cattle during the wet and dry season and according to different application methods such as spraying or dipping the cattle. Also, the consequences for the local rural population after contact with or ingestion of the acaricide were investigated.
His conclusions are that hand-spraying is much better than dipping, and that some additional and appropriate instruction of the poor rural population could be of great help in reducing the risk. The environmental consequences are also examined, but a valuable and efficient substitute for the use of acaricides has not been found yet.
