Organo-phosphate dips

The Soil Association prohibits the use of organo-phosphate dips against fly strike and scab, mainly because of the undoubted health risk to shepherds. However, there are dips that can be used which are effective and which do not contain organo-phosphates. Flumethrin-based compounds can be used against sheep scab. 

Two studies have been reported where a dog and cats were exposed dermally to insecticidal dips containing 78.2% D-limonene. Severe dermatitis was observed in the dog and, at five and ten times the recommended dose, excess salivation, incoordination, and muscle tremors (signs typical of organo-phosphate poisoning) were observed in the cats. The effects were reversible within 5 h in the absence of complete ingredient information, these effects cannot be completely attributed to D-limonene.
