When it comes to the transplant procedure, the hand-off between professionals is very important. Because of that, there are strict rules and regulations as to where and how organs can be procured, and how they can be transported to the transplant site. They need to go through the Organ Procurement Organization, and then follow the chain of custody to ensure they have been handled properly. http://health.howstuffworks.com/medicine/modern-treatments/organ-transplant.htm
