A Study on the Transfer of Organochlorine Pesticide Residues from the Feed of the Cattle into their Milk

Endosulfan was not detected in the milk of cattle when fed with it for four weeks @ 50 mg d⁻¹, however, the level of BHC residues in the milk of the animals increased soon after dosing began with BHC and it dropped sharply on discontinuation of the dosing. Similarly, feeding with technical grade DDT increased the level of p,p’-DDT in the milk. The low levels of p,p’-DDT in market milk samples indicated that the animals of this region were not being subjected to fresh ingestion of DDT to any great extent.
