§ The Countess of Marasked Her Majesty's Government:
How users of pirimiphos-methyl grain treatments are to reconcile instructions that "Grain treated by admixture as specified may be consumed by humans and livestock" without a withdrawal period, with the recently-added instruction to "Keep [the chemical] away from food and animal feedstuff", particularly in the light of the review of this chemical which revealed that it remains active for between one and five years in controlled conditions. [HL2588]
§ Lord DonoughueCurrent scientific advice is that pirimiphos-methyl does not pose an unacceptable risk to humans or livestock when it is used in accordance with the conditions of its approval. The instruction to keep it away from food and animal feedstuff is a standard precautionary measure designed to warn users of toxic compounds to avoid inadvertent contamination.
