  1. Process 1. APHA will be alerted if the level of a post-mortem condition is exceptionally high (exceeds mean + 6SD).
  2. Process 2. APHA will be alerted if the Cumulative daily mortality rate is unusually high (exceeds mean + 3SD = 7.37%) and, additionally, the rate of three or more post-mortem conditions is high (exceeds the mean).
  3. *The FPD score is not a percentage but is a score of the severity of lesions (between 0 and 200) based on scoring 100 feet as either score 0, 1 or 2.
