What is Grade D Beef?

Q: What does USDA 'wholesome' mean?

'Wholesome' is a legal safety standard indicating that meat is fit for human consumption and accurately labeled. It is a mandatory inspection for safety, but it is not a voluntary quality grade like Prime or Choice.

Grade D beef is a term often used in urban legends to describe low-quality meat allegedly served in fast-food restaurants, but it does not actually exist as an official USDA quality grade. While consumers are familiar with retail labels like USDA Prime, Choice, and Select, the American grading system uses names rather than letters for its categories. In contrast, Grade D beef does exist in Canada, where it refers to meat from older cattle typically used for ground beef and processed products.

The Short Answer: There is no such thing as Grade D beef in the United States. The USDA uses names like Prime, Choice, and Select for quality grading. The “Grade D” label is a persistent myth often incorrectly associated with fast-food meat quality, especially in regard to Taco Bell.

Why You Won’t Find Grade D Meat at the Grocery Store

The reason you never see a “Grade D” label at the butcher counter isn’t that stores refuse to carry it; it’s that the United States Department of Agriculture (USDA) doesn’t use a letter-based grading scale for beef at all. While other countries, such as Canada, utilize letters like A, B, and D to categorize quality, the American system relies entirely on descriptive names.

Mandatory Inspection vs. Voluntary Grading

It is important to distinguish between safety and quality of the meat. Every single carcass processed in the US must undergo mandatory inspection for safety, wholesomeness, and accurate labeling, which is funded by tax dollars. However, quality grading is strictly voluntary. Beef producers actually pay out of pocket to have USDA inspectors evaluate their meat for traits like marbling, tenderness, and flavor.

If a producer chooses not to pay for this service, their meat isn’t “Grade D.” Instead, it is simply “Ungraded”.

USDA Beef Grades

The best quality beef is USDA Prime. The second highest quality is Choice. And, the third is Select. The age of the cattle absolutely affects the grading with Prime beef coming from younger cattle. Of course, how well the cattle are fed makes a difference in marbling and flavor.

Prime beef: has the most marbling and it is the most tender and juicy. It will have at least slightly abundant marbling to moderately abundant marbling.
Choice: is still well-marbled and tender. It has less marbling than Prime but at least a small amount.
Select: is leaner than the higher grades but uniform in quality. It can still be a tender cut of beef but will be less juicy and flavorful than the higher grades.

Below USDA select are Utility, Cutter, and Canner grades. You won’t see these sold at the butcher section or served in restaurants. They are used for ground beef, processed products, and pet food.

The Myth: Taco Bell Uses “Grade D, But Edible Beef”

While the exact grade of beef Taco Bell uses in its seasoned filling isn’t public knowledge, the persistent claim that they use “Grade D, but edible” beef is 100% untrue. As established, the USDA simply does not have a grade by that name.

The confusion likely stems from a mix-up between official quality grades and industrial processing methods. For years, major food chains were criticized for using boneless lean beef trimmings (BLBT), more notoriously known as “pink slime.”

The “Pink Slime” Connection

In 2012, following a massive public outcry sparked by celebrity chefs and news investigations, Taco Bell announced it would stop using finely textured lean beef trimmings in its recipes.

It is important to understand that “pink slime” wasn’t a “Grade D” meat; rather, it was a processed filler made from fatty beef trimmings that were heated and treated with ammonium hydroxide to kill bacteria. While safe and “edible” by USDA standards, it became a symbol of low-quality, highly processed food.

Beyond the Label

Today, Taco Bell uses a mixture of ground beef, spices, and thickeners. While it’s unlikely they are using high-end USDA Prime or Choice cuts—which would be cost-prohibitive and lose their texture during the heavy processing required for taco filling, the meat is still real, inspected beef. The subjective difference between a “Select” grade and a “Utility” grade mostly disappears once the meat is ground, seasoned, and simmered into a uniform filling.

A viral myth insisted the fried-chicken giant was forced to change its name to KFC because they had stopped using actual chicken, but instead, used something cooked up in Dr. Frankenstein’s basement.

Beef Grades Have Nothing To Do With Healthiness

Regardless of the grade, it is a common misconception that higher-quality beef is “healthier” for you. All beef sold in the U.S. undergoes mandatory inspection for safety and what the USDA calls “wholesomeness.”

The “Wholesomeness” Weasel Word

In the context of government inspection, “wholesomeness” is often used as a bit of a weasel word. To a consumer, it sounds like a guarantee of nutrition or superior quality. To the USDA, however, it is a narrow legal standard meaning the meat is simply fit for human consumption and accurately labeled. It doesn’t mean the beef is safer or better for your body than lower-graded meat; it just means it passed the bare minimum safety check.

Grading vs. Eating Experience

Beef grading is actually a reference to a subjective eating experience. To put it differently, grading helps predict how much you will enjoy the meat based on tenderness and marbling once it is cooked.

Once beef is ground up, seasoned, and simmered—as it is in a fast-food kitchen—much of that “premium” experience is lost. If a chain spent more money on USDA Prime beef for taco filling, the consumer would pay a massive premium for a difference they likely couldn’t taste. This is why most ground beef you buy at the store isn’t a high grade; it doesn’t need to be to make a great taco.

If you like Taco Bell, there is no reason to fear the meat is “bad” for you. It has passed the same “wholesome” inspection as the most expensive steak in the country.

Grade D Beef: US vs. Canada

Because the “Grade D” myth is so persistent, many people are surprised to learn that it actually exists, just not in the United States. While the USDA uses descriptive names, the Canadian Beef Grading Agency (CBGA) uses a letter-based system for certain categories other than their “Prime” beef. While beef grading is not mandatory in Canada, their beef grades consist of:

Grade A beef: The three A grades (A, AA, AAA) represent increasing amounts of marbling from least to highest, AAA being the highest. This is meant to give consumers a choice of fat amounts. Around 98.5% of all beef sold in Canada is Grade A of some type.
Grade B beef in Canada is beef from young cattle that don’t meet the requirements for Prime or A-grade. These are visually less appealing and are usually used in products with further processing. Only about 1.6% of beef in Canada is B-grade.
Grade D beef in Canada is applied to older cattle, usually cows. This beef is usually used for ground beef or further processed products. It can be used for ground beef products in lower-cost food service establishments. Taco Bell would probably fall under this category. It is possible, but unverified, that Taco Bell uses Grade D beef in Canada. This type of beef represents around 11% of all beef in Canada.
Grade E is given to older older bulls showing pronounced masculinity.

The following table shows how Canada’s Grade D Beef compares to lower-tier beef in the U.S.

Feature	US (USDA) Equivalent	Canada (CBGA) Grade D
Typical Source	Older cattle (Commercial, Utility, Canner)	Mature cows
Common Use	Ground beef, canned soups, frozen meals	Ground beef, processed meat products
Appearance	Generally lower marbling; may have yellow fat	Variable marbling; fat can be white to yellow
Availability	Rarely sold as “steaks” in grocery stores	Sold mainly to processors or budget food service

As of my last check, there are 120 Taco Bell locations in Canada. I have been unable to find any information pertaining to Taco Bell’s use of Grade D beef in Canada, or as to what grade of beef they use in that country.

If they have used Grade D beef or continue to use it, it is perfectly edible and has nothing to do with ‘pet food’ or any type of meat that would be considered unfit for human consumption or disallowed in products meant for human consumption.

The quality and safety of our meat supply are of primary concern to consumers. While these concerns are legitimate, they lead to persistent myths about the quality of the beef sold in America. Myths about “Grade D meat” will likely persist, despite the fact that such concerns are easily debunked.
