I think that this is sometimes misleading marketing-speak. For example, Perdue says, "All of the animals for our branded products are raised in no-antibiotics-ever programs"; as a big company, surely this leaves enough vagueness for them to raise and sell animals with antibiotics under other brands/products. Since it's a private company, consumers can't know really what percentage of animals fall under one category or the other. https://corporate.perduefarms.com/news/statements/antibiotics-position-statement/ https://corporate.perduefarms.com/news/statements/antibiotic... Though it is interesting that such a big company would move towards that direction at all.
