INSPECTION AND SUPERVISION OF FOOD.
Milk Supply.—A general improvement in the method of distribution
of milk has taken place. There is an increased demand
for the supply of milk in sealed bottles. One large firm now supplies
the whole of the milk sold by them in this district bottled and
sealed at their depot, and this has made some of their smaller competitors
appreciate the advantage to their trade by adopting this
method. Milk in sealed bottles only is sold in practically all the
general shops.
No action has been found necessary as to tuberculous milk
and tuberculous cattle. There are only 3 milch cows in the district.
