Hang on a minute. My entire life there have been ingredients lists on food products, usually under the nutrition facts grid. More recently I've seen additional language on packaging that says something like "Warning: Contains nuts." Did they fail to put that "Warning: Contains milk" on there, or did they omit the ingredients list entirely (which, for butter, should be cream and maybe salt). Like...?

I also wonder if they'll be able to put the same butter into corrected packaging and still sell it.
