Question
To ask the Scottish Government what proportion of the active ingredient in the medicated grit that is used on managed grouse moors is excreted by the birds.
Answer
There is limited data available on the excretion of flubendazole, the active ingredient in medicated grit, by grouse. However, a 2006 study on Medicinal Products for Veterinary Use by the European Medicines Agency Committee involving a wide range of species, including chicken and game birds, found that more than 50% of the consumed drug was excreted. Furthermore, this trend has also been observed in studies involving human excretion of flubendazole.
