Still room for improvement in infection battle

While this is a good improvement on previous years, there is still room for improvement. The best 20% averaged 140,000, while the worst 20% averaged 320,000. There is great variation among farms and cows.
Herds which have SCC consistently above 250,000 are living with infection which is costly and difficult to control. Disappointingly, there are still 10% to 20% farms with SCCs ranging between 300,000 and 400,000.
