I was talking about large producers like Tyson or Foster Farms adulterating their products.

Your family is in a completely different league than them. I say this as someone who grew up splitting a cow from the farm with family members and having a local butcher do the work of splitting it into parts.

I bet the sausage they make is amazing!

Typically it's not the chain that sells it. It is the processor before it gets to the store, think of the prepackaged meats with the weight stamped on a sticker. Or even bulk bags of parts.
