So, can you tell us the major differences in halal and kosher?
Both religions have a strict prohibition against consuming pork products, and certain animals and birds.
But jewish kosher laws also forbid the eating of many sea and fresh water creatures. Whereas halal dietary laws allow the consumption of just about every type of water creature. .....
So, in other words, six of one, half dozen of the other.
I guarantee that they don't get such high quality meals anyway for this to be a problem.
I talked to someone who had been in prison for 5 years and will not touch chicken in any way shape or form since he had it for about 2/3rds of his meals while incarcerated.
