Small-scale traders represent the largest part of dairy industry in many developing countries through supply of unpasteurised 'raw' milk, boiled milk or traditionally processed dairy products. These traders often operate without a license because they are unable to comply with safety and other standards of production and delivery. However, poor farmers and consumers rely on the more affordable raw milk that, in Kenya, is nearly always boiled before consumption.

The quality and safety of milk are affected by the container in which it is transported. SDPs' consultation with traders and dairy experts resulted in established specification for "ideal" milk container. A private manufacturer has been found to produce the vessel at an affordable price. The container's size allows easy transport on a bicycle. An easy-release clip holds the lid firmly on top, avoiding spillage and contamination.
