A subscriber (Irina) asks, “The TSE Risk estimation document (Germany, 1994), “Safety Requirements for Medical Products Derived from Body Constituents of Cattle, Sheep, or Goats to Avoid Risk of Transmission of BSE or Scrapie,” requires an estimate of the TSE risk arising from the use of the product, taking into account the likelihood of contamination of the product, the nature and duration of patient exposure.

What is your opinion on this way of measuring risk? Can you give me some advice in this matter?
