What does somatic cell count?

What should TBC be in milk?

EU legislation indicates that total bacterial count (TBC) in milk should be less than 100,000/ml. However, ideally and on many farms, a TBC of less than 15,000/ml can be reached. Thermoduric bacteria counts of greater than 1,000/ml are generally penalised.
