What is the purpose of tagging milk tankers?

Tagging milk tankers serves several important functions in ensuring the safety and quality of milk as it is transported. The primary purpose of tagging is to indicate that the tanker is clean, which is crucial for maintaining the integrity of the milk. A clean tanker ensures that there is no contamination from previous loads, which can affect the quality and safety of the milk being transported.

The tag often includes information about when and how the tanker was cleaned, and it assures dairy processors and consumers that the milk has been handled according to public health and safety standards. This is particularly important in the dairy industry, where the risk of microbial contamination can have serious health implications.

While other options may have value in specific contexts—such as showing the destination of the milk or marking cleaning requirements—these are not the primary objectives of tagging. The focus on cleanliness directly supports product safety and quality assurance in the transportation of dairy products.
