1) If you parents are Christians/Jews, then they are considered pure and you can eat anything they touch with wet hands.

But if they are or a different religion, then technically their body is not pure. If they touch food with wet hands, you have to wash the food with water before eating it.

But you don’t have 100% certainty they made it najes
Consider everything pure unless you know it’s najes
And even if it’s najes it’s ok to touch it, just make sure to wash your hands before praying
