1. You may notice the color difference in the picture. The store bought is pumped full of additives and preservatives, including propyl gallate, to protect against spoilage due to long term air exposure.

2. There isn’t a guarantee of where that beef came from, OR how many cows are in it.

Yes, it may have the USDA label on it but as long as that animal was packaged in the US, it can be called a Product of the USA.
And yes, the meat in the right package is not from one single cow, rather scraps from multiple cows.

3. The beef on the left is fresher, darker and is farm raised beef. It is filled with more nutrients & flavor. The ground is also from one cow and not just low quality scraps from multiple cows.
