Exactly. What did Muslims around the world and in Australia eat before halal certification?

They ate the same foods they are eating now

They say a small private prayer over the food before they eat it.

I know this as i recently sat next to a muslim teacher at a school christmas dinner. She was lovely and we started discussing the foods she can and cant eat.

She said that whether the food is stamped halal certified or not makes no difference to her as she still says her prayer over the food anyway
