Your OCD is getting best of you. There is no need for concern and no need for testing. It is most probably that the blood was from the meat, not a human. If it was from a human, it is unlikely that the human had HIV and finally and most importantly, even if it was human, HIV infected blood, there is no risk from swallowing infected blood.
Again, no risk, no need for testing. EWH
sorry the last sentance was (is it a mode of transmition?)
