Their answer to me:
Since peanuts are part of the Eight Major Allergens, they will be listed on our labels if present. Additionally, the allergen risk management program in place at our facility would include listing a "May Contain" statement on our labels if there were potential cross-contact with peanuts. As always, we suggest reviewing the packaging as product formulas and packaging may change. Thank you!
That totally didn't answer my questions about shared lines and washing between runs. Asked about that and we'll see what they say.
