It is up to the designer to decide what level of safety is required for the installation and so then specify the required level of resistance that is acceptable to determine the identification of extraneous conductive parts.
Generally 10mA is used because it is a catch all situation, not too bad not perfect.
If you have lots of large animals then less than 2mA may be the best approach, if there is minimal chance of any accidental contact and everyone in the area is adult then 30mA may be suitable.
I was thinking that might be in an industrial or commercial setting, but then the chance of accidental contact would probably be greater.
