Hon DAMIEN O'CONNOR (Minister of Agriculture): Very briefly, thank you, Mr Chair. On the methane inhibitors, look, there is an issue of definition of them. And the methane inhibitors used offshore have usually—or some of the ones that have been deemed effective—been fed on a regular basis during the day to animals that are housed indoors. But, actually, there's an unknown outcome from feeding it for pasture-based systems. So therefore, if you were to feed a larger volume of that in one hit—whether that would then result in residues in the meat or the milk, that would then block us. So officials are working very carefully as to the definition of it under the Agricultural Compounds and Veterinary Medicines Act, whether it's a fertiliser or whether it's a veterinary medicine.
