Avram in MD, who is so wise, figured out how to make romaine lettuce that doesn’t ever need to be checked. (You may call me the devil, if you so wish.)
Suppose you have a world with no bugs in it. None. And then you grow some romaine lettuce. You don’t need to check that lettuce before you use it for maror, or on a sandwich, or in a salad. Because there are no bugs. It’s that simple.
And of course this is totally applicable to the real world. 🙂
