^aTotal number of unique identity farms that were visited by BTEC from 2015 to 2020. In the columns to the right, data are the number of tests applied and the unique identity farms or animals tested or with positive results in that year. Many farms and some animals were tested more than once per year; the same farm or animal can appear in more than one year, but within a year a farm or animal appears only once.
