That's a fine sell. Now sell me on, "this is so OK that we should have a statutory right not to ever mention this fact.
Which is to repeat the point that this tug-of-war isn't about "can you do it?" or "is it safe" but "do you even have to say anything?".
The problem is indeed how little consumers can determine about safety once it becomes obvious industry is throwing things all in a giant food processor and then mixing up things that appear simple. It makes people nervous even if, let's say, in this case everything is fine.
Because, suppose, in the case of antibiotics, everything is not fine at all? Do you want the precedent that "hey, once the expert decide everything is OK, then it's decided that things are sooo OK that you aren't allowed to talk about it at all". Which is to say, safe or not, problem or not, it's pink slime. That was what it was called before ABC and that's rather clearly an appropriate term.
And pink slime is shocking because consumers don't know anything. Keep the situation where the real processes of food production are shocking and hidden? Good idea? I believe not.
