Testing every milk tanker for antibiotics does not, however, ensure that no antibiotics from normal farm animal health practices reach consumers through milk.

Testing every milk tanker received at a processing plant is a somewhat more manageable number, approximately $21, 000, 000, but represents testing for just one contaminant.

The collection tanker will then deliver the milk to the dairy where the contents are sampled on receipt, inspected by smell and taste and tested for bacteriological and compositional quality.
