Werribee Pesticide Survey 26 November 1974

… As a result of a high pesticide reading in PDC depot milk sampled at Metropolitan Dairy Broadmeadows…

I sampled each individual farm of the drift on 12/9/74. Results which have just been made available, showed 7 excessive readings in Dieldrin and one high DDT sample.

… One common factor emerged from my investigations. All seven farms had adjoining market gardens. In several instances farmers remembered sprays being used on vegetables about that time.

Enquiries at Werribee South store showed that a chemical “Dieldrin” contaiing Dieldrin is widely used as an insecticide. I suggest that spray-drift from market gardening spraying is responsible for the high Dieldrin level and most likely the DDT case also.
