The meat itself was fine so I don't like rating it as "negative quality" but the amount of fat was unacceptable. The meat was swimming in fat in the pan.

After moving the meat to paper towels, I poured the fat that was left in the pan into a measuring cup. There was more than 1/4 cup of fat rendered from one pound of ground beef.

For comparison, I paid extra attention when I later cooked up a 2-lb package of ground beef from Miller's farm. There was no accumulated fat in the pan, just a slight slick to the bottom of the pan. Night and day difference.
