In all fairness, the USDA has been useless for a long time.
Just one of many examples, “treatments” are not considered ingredients, so they don’t need to be disclosed to the consumer. McDonald’s takes mechanically separated chicken bits leftover from Tyson’s boning process, then mixes them with ammonia to kill bacteria, homogenizing it into a pink slime. That slime is pressed into four shapes distinct shapes, “breaded” and fried, and the ingredients list for McNuggets is not required to include ammonia.
