Question
What studies have been conducted into the amounts of pirimiphos-methyl likely to be ingested over their lifetime by: dairy cows and barley beef fed on diets which include the whole grain and bran which has been treated with that chemical over an extended period on the farm, in intervention stores and by feed manufacturers; and what effects this diet alone, or when combined with treatment of the animals with phosmet warble fly dressing, organophosphate impregnated fly tags or collars and synthetic pyrethroid insecticides, would have upon the brains, central, autonomic and peripheral nervous systems and reproductive systems of the animals; and if there have been no such studies, whether they will commission this research using each chemical at the levels generally in use between 1980 and 1990.
