geminianeyes | Blood donation question

This darling little question came up while I was half-asleep yesterday (followed by one hell of a nasty nightmare).

How do the major religions with food rules deal with blood donation? Hindus don’t take beef, Muslims don’t take pork etc. In a country like Malaysia, how do you deal with the blood donation issue? Are Muslims only given blood from Muslims? Hindus only blood from Hindus?

Just curious about this. Links and discussions welcomed!

PS: Twitter friends, please reply here and not on Twitter. Easier for me to keep track of things.
