McDonald's stopped using "pink slime," or ammonia-treated beef, in its burgers starting in 2011, with the ingredient fully out of their U.S. supply chain by August 2011, and the company officially announced the discontinuation in early 2012 to align with global standards for sourcing beef. While the controversy gained public attention around 2012 due to chef Jamie Oliver's campaign, McDonald's stated the decision was made earlier to create consistency across their worldwide beef sourcing.
Some consumers may be familiar with the practice of using lean, finely textured beef sometimes treated with ammonia, which is referred to by some as “pink slime.” We do not use this. Still curious about what's in our burgers.
Let's set the record straight: this image in connection with McDonald's is a myth. In fact, we don't know where it came from, but it's not our food.
In 2002, a United States Department of Agriculture (USDA) microbiologist argued that the product contained connective tissue and that he did not consider it to be ground beef and that it was "not nutritionally equivalent" to ground beef. BPI claims no such connective tissue is used in their product.
Did you know that McDonald's used to use beef tallow to make their fries from 1940 until phasing it out in favor of seed oils in 1990? This switch was made because saturated animal fats were thought to be unhealthy, but we have since discovered that seed oils are one of the driving causes of the obesity epidemic.
Now that the sting of miracle french fries has passed, you may be wondering, “But what about the fries?” As we mentioned before dimethylpolysiloxane (or PDMS) is the silicone compound McDonald's uses in its french fries to prevent the oil from foaming.
But nutrition experts quoted in the article cautioned against using beef tallow, noting that it is high in saturated fat, which is much worse for heart health than unsaturated fats such as vegetable oils (which include seed oils and others such as olive and coconut).
So how can you know if you're eating this additive? Simply look for the term "finely textured beef" or just "textured beef." That's the popular name for pink slime today, according to meat packer Cargill. The beef processing operation offers that juicy tidbit and more on the website GroundBeefAnswers.com.
Dimethylpolysiloxane, a type of silicone, is added as an anti-foaming agent to the nuggets. This is the same ingredient that is used in breast implants and silly putty (and is now being phased out due to health concerns), and this ingredient is now marketed towards children —one- third of which are obese.
After several years of bad press, all three companies have decided to stop using ammoniated beef. Both Burger King and McDonald's released statements to say that their move was in no way connected to the negative press and Taco Bell did not release any statement.
It's regulated by the U.S. Agriculture Department, which classifies it as "generally recognized as safe." The USDA has been purchasing the "pink slime" for years, using the product as a filler.

The paste typically contains a mixture of zinc oxide and eugenol, which provides both adhesive and soothing properties.
“Pink slime” is a type of ground beef that has been treated with ammonia to keep bacteria or other pathogens like salmonella from forming. The process starts with cuttings and trim from cattle carcasses that are sliced up into little steaks and sent away to be turned into ground beef.
However, periodic and thorough cleaning of the surfaces where the pink slime occurs, followed by disinfection with chlorine bleach appears to be the best way to control it.
In McDonald's case, this was exacerbated by a viral online rumor, which supposedly showed a rough-looking mixture of smooth meat called "pink slime." The burger chain is not totally off the hook for using pink slime in the past, but the mixture is not and never was used in Chicken McNuggets.
Ammonia gas is used to treat the beef slurry as it passes through specially designed stainless steel pipes. Some of the ammonia dissolves in the meat's moisture and maintains the alkaline conditions needed to control bacteria. Neither the dissolved ammonia, nor the ammonium hydroxide it forms presents a health concern.
The unhealthiest item at McDonald's is often cited as the Big Breakfast with Hotcakes, packing over 1,300 calories, nearly a full day's sodium, and significant saturated fat, making it a calorie and nutrient bomb, with other contenders including large shakes, certain Angus burgers, and large fries.
Before August 2016, dimethylpolysiloxane and TBHQ were listed as ingredients in the McNuggets cooking process. According to Lisa McComb, a media relations representative for McDonald's, dimethylpolysiloxane is used as a matter of safety to keep the frying oil from foaming.
Chemical changes occur during cooking. Oven gases in a heated gas or electric oven react chemically with hemoglobin in the meat tissues to give it a pink tinge. Often meat of younger birds shows the most pink because their thinner skins permit oven gases to reach the flesh.
Previously, pink slime was sometimes folded into ground beef sold in supermarkets, or more commonly sold to fast-food purveyors for use in burgers. The anti-contaminant treatment used by BPI is ammonia, which is legal in the US but not in Canada or in the European Union, where pink slime is thus banned.
Whole Foods also confirms to Consumer World that all its ground beef, both fresh and frozen is pink slime-free, as does Costco.
Ammonia has diverse chemical processing uses, from a leavening agent and acidity regulator in food manufacturing to caramel coloring in food and beverage production. Ammonia hydroxide applications help encourage cheese cultures to grow, reducing its cultured acidity level for healthy cheese development.
Beef tallow is a rendered form of fat taken from cows. Workers kill the cows, then melt down the hard, white fatty layer around their organs. Beef tallow is sometimes called “beef drippings.”
“Beef tallow is high in saturated fats,” says Ansari. “High intakes of saturated fat contribute to elevated LDL cholesterol levels and increase risk of heart disease.”
We stopped using tallow primarily due to health concerns in the late 20th century, specifically its high saturated fat content linked to heart disease, leading to a shift towards vegetable oils in commercial cooking, though some trends now re-evaluate its place in diets. A major catalyst was a public health campaign by Philip Sokolof in the 1980s, who used newspaper ads to highlight saturated fats in foods like McDonald's fries, causing companies to switch oils to avoid backlash and lawsuits, notes Yahoo and Reddit r/todayilearned.
