What to do if Milk is Rejected
High quality milk and milk products start with quality milk supplied by dairy farms. However occasionally milk doesn't meet regulatory standards and must be rejected. Bulk Tank Milk Graders (BTMGs), more commonly referred to as 'drivers', are trained and certified for their duties associated with collection of milk at the farm including grading of milk in the bulk tank to determine whether or not it is 'acceptable'.
Criteria used to determine milk acceptability is provided in Regulation 761 of the Milk Act (Ontario). Section 51 (1) of the regulation requires that a BTMG reject milk that,
In addition, milk must be cooled as quickly as possible after milking. Farm bulk tanks must be capable of cooling milk to a temperature of 4°Celcius within 2 hours after the completion of milking. Once cooled, milk temperature must be maintained between 1 and 4°Celcius for the duration of storage. Check with your milk broker for acceptance criteria related to milk temperature at time of pickup.

It is the producer's responsibility to empty the rejected bulk tank of milk, dispose of the milk in an environmentally approved manner and wash the bulk tank prior to the next milking. Milk brokers will monitor subsequent bulk tanks of milk for irregularities in volume.
Grading milk is a vital step in the system that protects the quality and safety of the milk supply. Producers and BTMGs both have important roles to play in ensuring only acceptable milk is marketed.
