Ireland has a very positive story to tell when it comes to national udder health. CellCheck, the national mastitis control programme, was launched in 2011 in response to industry concern that bulk tank somatic cell counts had been slowly rising over the previous decade. Since then, the story has changed significantly.

The national bulk tank somatic cell count (SCC) has reduced from 272,000 cells/ml in 2009 to 183,000 cells/ml in 2018, which is a phenomenal achievement and one that the industry should be extremely proud of (Figure 1).
