"Pink Slime" in Chicken Nuggets?
02/22/2012
After an inquiry regarding mechanically separated chicken in chicken nuggets, we asked Dr. Casey Owens from the University of Arkansas for some clarification. She maintains that this is not the process used to make nuggets.
Many of you have seen it: the so-called "pink slime" video where food celebrity Jamie Oliver seeks to demonstrate to children how chicken nuggets are made. If you haven't seen it, you can view it here:
We talked with Dr. Casey Owens, Associate Professor in the Department of Food Science and member of the Center of Excellence for Poultry Science at the University of Arkansas, to learn more.

Best Food Facts: We received a question from a Best Food Facts reader who wants to know what food products come from "mechanically separated chicken."
Dr. Owens: "Typically, mechanically separated chicken serves as an ingredent for products like hot dogs, bologna, and Vienna sausages - emulsified products. The processor he uses in the video is not what would be used in the industry, nor would this process be used for chicken nuggets as the video suggests."
Best Food Facts: Why is mechanically separated chicken used?
Dr. Owens: "Mechanically separated chicken (MSC) contains proteins that are useful for other products. It takes on a fine, pasty texture, so it can be formed into a desirable shape. Consumers should note that products using MSC typically have a higher fat content."
Best Food Facts: In this video, the people say that the pink in the meat is from blood, that eyeballs are mixed into the paste, etc. What is the truth?
Dr. Owens: "First and foremost - there is NO chance of eyeballs being in the chicken, because the head is removed much earlier in the process. In the Jamie Oliver video, you can see there is no head on the chicken he presents to the children - the same is true in processing facilities. Mechanically separated chicken is made using the meat left after the breast meat and legs are removed - meat found between the ribs, near vertebrae, around joints, etc. as well as some fat, connective tissue and skin (if there is any that remains on the carcass). There will also be trace amounts of bone, which provide calcium - but bone content is monitored closely as only so much calcium is allowed in MSC. Lastly, some of the meat will appear darker in color becasue it either came from legs (dark meat) or is bone marrow (if bones are broken in the process, some marrow can come out)."
Best Food Facts: Take a look at the picture below. The video says this is mechanically separated chicken. What's your take?
Dr. Owens: "Well, it would be great to know the source of that image, because without it, anyone can claim it is anything. If it is any type of meat, I would guess that it is a hot dog batter - not chicken - because of the coloring. When a meat emulsion is made (ie., hot dog, bologna), it becomes lighter in color because of the stable mixture between fat and water that is formed. Kind of similar to the reason mayonnaise is white. Because poultry meat is relatively light anyway, color (e.g., paprika) can be added. The nitrites generally found in cured products (i.e., hot dogs) also create a color reaction in the meat, causing it to have a reddish/pinkish color in meat."
Best Food Facts: Do you eat meat that has gone through mechanical separation?
Dr. Owens: "Yes - in fact, I happen to like hot dogs!"
Best Food Facts: If consumers don't want to eat MSC, how can they avoid it?
Dr. Owens: "If MSC (or MST - mechanically separated turkey) is used in a product, it has to be listed on the ingredient statement as “mechanically separated chicken” (or other species). It would not be listed as just “chicken." Overall, I encourage people to read their ingredient statements before coming to any conclusions. If they are not satisfied with those ingredients, they can choose another product."
How about you... do you eat products like hot dogs and bologna that have been emulsified? Tell us in the comments section below.

I say that the chicken nuggets are growess how they make the chicken nugeets i say stop making them becuase somebody is going to get sick with thIs stuff.

Meg Cossman: Thank you for your inquiry. We have asked Dr. Owens and she will be looking into the specifics once she returns from vacation, but she did share this: "Fat content is generally higher. MSC is used in emulsified products which generally have higher fat content than whole cuts of meat. It still contains the proteins and the calcium can only be up to 0.235%."

M. Leland: To my knowledge, ammonium hydroxide is not used to treat ground turkey. Ground turkey is not processed the same as lean beef trimmings. For your second question, ground turkey meat is not cured, so there is no worry of nitrosamines forming. Theoretically, nitrosamines can form in cured products when subjected to high temperatures. However, even bacon (normally subjected to high temp as compared to hot dog) has a lower limit of added nitrites to reduce chances of nitrosamines forming.

Hot dogs and bologna are processed meats that have been infused with nitrates and nitrites as preservatives, which have been known to cause cancer. I've blogged about it in my blog post entitled: "Hotdogs and Bacon and Cancer, Oh my!" on my blog page: trylivingorganic.com - worth taking a look at! It could save your life if you are a big hotdog eater.

I would like to know the nutritional content of the MSC compared to chicken breast meat or leg meat. Does the increased percentage of bone/cartilage/connective tissue significantly lower its nutritional value?

Ralph then you agree Solent Green is the way to go next.

It's been years since those 1lb "ground turkey" chubs appeared to be regular ground (they're all mech sep. now). Is this also treated with ammonia. Concerned about high temp cooking creating nitrosimines (previously only worried about in hot dogs). what are implications now for char broiled beef/turkey burgers?

It seems like people spend a great deal of time tearing down foods so you eat what they want you to by default, not truly by choice. Is this person really doing a public service and should these young kids have seen him doing this? I would really object if they were my kids. We do have to feed the world. That means making use of all the food that we can.

I am sure I have eaten this kind of food. Guess I will be a better ingredient watcher now.
