Survey of pesticides used in the control of ectoparasites on farm animals in Ghana.
A study to identify the various types of pesticides used on farm animals in Ghana for the control of ectoparasites was conducted in 1989. Eleven organisations involved with pesticide use were questioned. Thirty organised farms and 110 kraals distributed throughout the 10 regions of Ghana were visited. Twenty different pesticides were in use. Of these 45% were organophosphates, 30% were synthetic pyrethroids, 15% were carbamates and 10% organochlorines. The most widely distributed and used pesticide was an organochlorine (lindane), which accounted for 35% of those used on farms and 85% used by herdsmen. The most popular mode of application was by hand dressing. No withdrawal periods before slaughter or sale of milk for consumption were practised. The implications of these findings in the light of possible emergence of pesticide resistance and health hazards are discussed.
