B y the first of August, data from almost 413,000 cattle had been reported to the ICBF database, of which the majority (38%) were steers, followed by heifers (30%), cows (18%), young bulls (13%) and bulls (1%). Analysis of data from these animals for liver fluke found that overall 15.1% had evidence of liver damage caused by fluke, with live fluke present in a further 3.3%, albeit with marked variation between different categories (Figure 1). Consistent with previous reports, there was also marked variation between counties, with fluke typically being commonly detected in western and northern counties (Figures 2, 3) .
