Hi Ms Kira!My husband & I, are dairy farmers residing in New Zealand!As, Ashen, has outlined above our Dairy Company enforces the same regulations as Canada does....ALL antibiotics/pencillins are strictly prohibited & yes, the whole tanker-load of milk is considered contaminated & discarded if any has gone into the milk vat & a hefty fine is given.MILK is a great source of calcium, for the wellbei
