Each week a new question about swine with the possibility of answering questions from previous weeks.

With respect to the production of haemoderivatives in Europe, What does the new Regulation of 8 May 2014 demand?

The dehydrated blood and blood plasma must be subjected to a heat treatment (80ºC) and then stored for a certain time period at room temperature.
The dehydrated blood and blood plasma must be subjected to a heat treatment (80ºC) for 10 minutes.
The dehydrated blood and blood plasma must be subjected to a heat treatment (100ºC)

See a clue in the article Risk-benefit of the use of blood products and other animal proteins

The correct answer is the first one. The Regulation demands that the spray dried blood and the blood plasma are subjected to a heat treatment (80°C) followed by a subsequent storage for a “certain time at room temperature” in order to reduce the risk of contamination after the treatment. Unfortunately, it does not specify the length of the heat treatment, which must be of 10 minutes at least for the most resistant viruses.
