A significant number of Americans practise Judaism/Islam. Should the government prohibit the use of food products containing pork in tax funded school lunch programs ? Should pork be listed as an ingredient if it is in processed food products?
And what about the Buddhists who are vegitarian? Clearly, we need to remove all meat from the school lunch programs.
Seriously, as long as their are alternatives, I don’t see it as a problem. On a practical note, people who keep kosher usually bring their own food from home.
