Am I allowed to eat steak tartare or meat cooked medium rare?


“This is a lasting ordinance for the generations to come, wherever you live: You must not eat any fat or any blood.” Leviticus 3:17
“Anyone who eats blood must be cut off from their people.” Leviticus 7:27
            People drank blood back then for other religious rituals, believing it gave them power and life (like vampires in stories today). 
            Also, God understands that certain diseases could be transferred through the blood unless it was cooking thoroughly.  For those reasons he wanted to make sure the people ate cleanly.
