From the HSE website:
In agriculture there were 26 fatal injuries in 2008/09 with a corresponding rate of 5.7 deaths per 100 000 workers. This compares to a rate of 9.9 when an average of the previous five years is examined.
For the last 10 years at least the figure has stayed around the 50 deaths a year mark so this really is something of a break through.
