BANNING OF DIPS

Manufacturers To Appeal

Nine manufacturers of dipping materials containing dieldrin and aldrin are to appeal to the Magistrate’s Court against a decision to deregister preparations containing these ingredients from the end of September this year. The appeals are being made under the Stock Remedies Act, 1934, which provides that if the Stock Remedies’ Registration Board refuses to register any stock remedy the applicant may, within 28 days of being officially informed of the board's decision, apply to a Magistrate's Court for an order reversing the decision. The purpose of the ban on the use of the materials is understood to be to protect New Zealand meat from contamination. It is an outcome of investigations by the Denartment of Agriculture and the Department of Health.

Manufacturers have been given seven months in which to adjust themselves to the ban. but only two of these months fall within the dipping season, and manufacturers are reported to be holding large stocks of raw and formulated materials which could be left on their hands if the ban comes into force as planned.
