Most of our kashrus today is commercial. Getting hung up on what the symbols on the packaging says, doesn’t tell you if it’s a chumrah or kulah. [Example: Muchzak bli tolayim when there are aphids still on the leaves. The same is true for meat and dairy.]
There are kashrus standards for you own kitchen. In someone (That you would marry or learn Torah from.) else’s kitchen, you take on their standards. You have specific kulos for when you are in tight situations.
This is all routine. The real question is, do you eat by every public event without caring?
