Milk Temperature. Milk received at the factory with a temperature higher than 5.0°C is non-conformant, an investigation by Norco Foods and Milk Supply to determine the cause of the high temperature will be conducted. An assessment as to whether the milk is within specification will be made. In extenuating circumstances, milk above 4.0°C can be collected on-farm subject to review of the situation by Norco Milk Supply.

Milk Temperature. Milk cooling is a critical component in maintaining milk quality standards. To comply with food safety regulation, dairy farm licence and export market requirements, milk must be cooled to 5°C or less within 3.5 hours of the commencement of milking. To maximise transport efficiencies, milk may be collected soon after milking even though milk may not be cooled to the expected temperature. Should the supplier’s milk collection occur within 2 hours from the completion of milking, milk may be pumped into the milk tanker at temperatures above 5°C (subject to conducting sensory grading and applying the temperature assessment in Graph 1). In applying the temperature assessment in Graph 1, tanker drivers will use the milking completion time displayed in the supplier’s milk room as the basis for the calculation. Failure to clearly display accurate milking times may result in a supplier’s milk being rejected due to temperature non-conformance. For milk out of the above temperature and time specifications, in the first instance, the Supplier’s Field Services Officer will contact the supplier to ascertain the cause of the issue, which is then to be rectified and a Corrective Action Report completed. Subsequent failure to eliminate the problem, may result in the milk being paid as grade milk. The supplier must contact their Field Services Officer immediately when milk cooling is interrupted for example, due to vat breakdown or power failure.
