The USDA has a letter-grading system for maturity of the cow. It runs from A to E-
-A is an animal less than 30 months old, D is an animal that's between 6 and 8 years. E is any animal over 8 years. Basically, grade D and E cattle are used-up milk cattle. It's thoroughly possible they'd use this beef in their products; there's absolutely nothing wrong with it and all that time on the hoof would give it lots of good flavor. The odds of them using it are very low, though, because there's just not that much of it. Most beef in America is slaughtered before the animal reaches 30 months, so you can figure most of Taco Bell's meat is going to be A grade.
The grade I suspect Taco Bell uses is called "standard-minus."
If only someone who actually KNOWS the answer would kick their two cents' worth in...
I believe the boxes containing the dining halls meat shipments say it best - Grade D But Edible.
Surf to http://www.epicportions.com/2009/12/02/taco-bell-grade-d-meat/. Taco Bell is using non-food in their meat. I wonder what that is. Cat food? Dog food? Does anyone know?
A B C after that grade D
No, the only failing grade is an F. D is just below average.

A D is a passing grade for 9th grade. It is the overall average of all grades that makes the difference between passing and repeating a grade.
Probably a D grade.
1.0
This will vary from school to school. At most times a D is a passing grade, but at some schools if you get 3 D's than you would go to summer school. If given a D you are given partial credit.
4th grade :D
It will have a bad effect on your grade.
Usually, it will be a grade of 'D+'
