Processed Meats: Convenience, Nutrition, Taste
Processed meat and poultry products like bacon, hot dogs, sausage, ham and other deli meats are great American traditions and iconic foods. In fact, bacon is often called the ultimate “conversion food” because it tempts even the strictest vegetarian. Processed meat and poultry products are commonly called “convenience meats” because they have already been prepared for easy and safe consumption by consumers. These products are offered in a variety of choices so the consumer can make the best food decision for their lifestyle.
Ninety six percent of Americans make meat and poultry products part of their diets. But recently, questions have arisen about processed meat and poultry products. What are they? How are they different from fresh meat and poultry products? Are they safe and nutritious? This consumer guide aims to provide the facts about processed meat and poultry products. It also offers a guide to the many choices available in the meat and poultry case today. In this way, armed with information, you can make the best choice for you and your family.
Processed Meat’s Ancient History
Historically, salting and smoking preserved meats and kept them safe to eat for longer periods of time.
Meat processing has its roots in the salting and smoking of meats that began centuries ago before refrigeration was available. Salting and smoking preserved meats and kept them safe to eat for longer periods of time. Many of these products are culturally important in other parts of the world like Europe and as people have immigrated to the U.S. in the last two centuries those traditions have developed into the U.S. culture.
While refrigeration is widely available today, over time, many people have come to appreciate the taste, variety and convenience that processed meats can offer.
The common thread is this: processed meats are fresh products that have been changed from their original state. Some have added ingredients like spices. Some are cooked and some are cured.
So What Exactly IS a Processed Meat?
Processing can take many forms. Processed meat and poultry products are a very broad category of many different types of products all defined by having undergone at least one further processing or preparation step such as grinding, adding an ingredient or cooking, which changes the appearance, texture or taste.
Some processed meat and poultry are ready-to-cook, like fresh breakfast sausages that contain meat ground with spices or other flavorful ingredients, or a turkey breast that is marinated and ready-to-cook.
The ready-to-cook category also includes uncooked smoked sausages that are mildly cured through the addition of sodium nitrite, an ingredient that imparts a characteristic pink color and distinct taste. Uncooked, smoked sausages require cooking before eating. Examples include kielbasa, mettwurst and Italian pork sausage.
Other processed meat and poultry are ready-to-eat. Some are smoked sausages that are cured and cooked. They include frankfurters, ham, knockwurst, bologna, mortadella and other luncheon meats. Other processed products such as sliced roast beef and turkey are not cured, but cooked with other ingredients to enhance flavor and more recently to improve food safety.
Linked, cooked smoked sausage like hot dogs and knockwursts are typically consumed steaming hot. Lunch meats or deli meats include products such as pimento loaf, olive loaf, sliced turkey, corned beef and cooked roast beef that are typically consumed without further preparation. Some traditional lunch meats are jellied, like souse and head cheese.
Other ready-to-eat processed products are cured and fermented using seasonings, sodium nitrite and lactic acid, which provides a tangy taste. These products include salami, pepperoni, summer sausage, thuringer and cervelat. Some are called dry and some are called semi-dry depending upon the moisture level in the final product.
The list goes on, but the common thread is this: processed meats are fresh products that have been changed from their original state. Some have added ingredients like spices. Some are cooked and some are cured. Some are ready-to-cook and some are ready-to eat.
Processed Meats Offer Good Nutrition
Processed meats are commonly made from beef, pork, chicken and turkey and each of these offer high quality protein, vitamins and minerals. They can fit into the U.S. Dietary Guidelines eating plans.
Meat and poultry are uniquely rich in protein and absorbable essential vitamins and minerals including iron, zinc, and vitamin B12. These foods are also rich in selenium, choline, vitamin B6, thiamine, niacin, and riboflavin.
Protein from animal sources, such as eggs, milk, beef, pork, poultry, or fish, is of the highest quality becuse it provides all of the essential amino acids. Vegetarian diets must contain a wide variety of plant protein sources in order to provide the complete array of amino acids needed for health that are naturally present in meat and poultry.
When it comes to iron and zinc, the type found in meat and poultry is more “bioavailable,” meaning they are more easily absorbed and utilized by the body, than these same nutrients from grains or vegetables.
Processed meat and poultry products – and all meat and poultry products – also are nutrient dense foods, meaning they provide a high amount of nutrition benefit per calorie.
While meat and poultry processing often uses salt for flavoring and to enhance food safety, meat and poultry processors have been actively engaged in efforts to reduce sodium and offer a wide array of choices with different sodium content, including reduced sodium, in which a product features 75 percent reduction from the original formulation, and low sodium, which contains 140 milligrams or less per serving.
Similarly, for those watching their fat intake, meat and poultry processors offer options that contain less fat.
Do We Eat Too Much Meat, and Particularly Processed Meat?
The Dietary Guidelines for Americans, 2010 recommend that Americans consume between five and seven ounces from the meat and beans group (now called the protein group) per day. Federal data show that women consume, on average, 4.4 ounces per day from the protein group while men consume 6.9 ounces depending upon age, gender and level of activity 1. Just a small fraction of total meat and poultry consumption is processed meat and poultry.
While there will always be people who over-consume or under-consume, the data suggest that on average, consumers are consuming meat and poultry at recommended levels.

Ingredients in a Popular Meatloaf Recipe from Southernfood.com
- 2 eggs, beaten
- 1/3 cup ketchup
- 3/4 cup water
- 1 packet dry onion soup mix
- 1 1/2 cups bread crumbs
- 2 pounds lean ground beef
What’s the difference?
The USDA-inspected product that meets USDA label requirements must detail all the ingredients in the product. Each component in ketchup, onion soup and bread crumbs is detailed on the pre-made meatloaf, making it look more complex than the homemade one, when they are actually strikingly similar.
Home Cooking = Meat Processing
All meat and poultry needs to be processed in some way before it is consumed. At home, a food preparer may marinate a chicken breast in lemon juice or teriyaki sauce and then grill it. She or he might make meatloaf by combining raw ground beef with spices like salt, pepper, ketchup and onion powder and then egg and bread crumbs to “bind” the meat together into a loaf and then bake it at 350 degrees F° for an hour. This is very similar to the process used in meat processing plants, where it’s done on a much larger scale.
Consumers sometimes wonder why an ingredient label on a processed product appears to contain more ingredients than a recipe used at home. That’s because a recipe may say “1 cup bread crumbs.” At home, the consumer typically reaches for a container of bread crumbs and thinks nothing more. At a processing plant, the food must be labeled as containing bread crumbs, but then must also declare any ingredients used to make those bread crumbs, like salt, parsley, preservatives and more. (See Box Above). The finished product is the same, but the commercially prepared label looks more complex.
Inspection and Labeling
Meat and poultry products are inspected by U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) every day. Inspectors monitor plant sanitation, proper processing and cooking, when applicable.
As part of their duties, inspectors also check to be sure that labels accurately reflect product ingredients. Any ingredient used in a processed meat or poultry product must be declared on the product label.
Safety and Preparation
The CDC recommends that pregnant women, the elderly, and other immune compromised people reheat lunch meats until steaming hot before consuming them.
Processed meat and poultry products have an excellent safety record. Some processed meats, like a marinated chicken breast, require additional cooking. Consumers should follow instructions on packages carefully and use an instant read thermometer to ensure that the product has reached the proper internal temperature.
Ready-to-eat meat and poultry products, like hot dogs, cooked ham, deli meats and salami, are pre-cooked. When processed in plants, scrupulous sanitation is used to ensure that they are safe and free of bacteria when packaged. However, on very rare occasions, a product may not be 100% free of bacteria like Listeria monocytogenes, which can pose a risk to certain higher risk populations. Pregnant women, the elderly and other immune-compromised people should follow the Centers of Disease Control and Prevention (CDC) recommendations2 to reheat lunch meats and other ready-to-eat meats to steaming hot before consuming them.3
Why Is Sodium Nitrite Used?
A panel of experts reviewed NTP’s findings and concluded that nitrite was safe at the levels used and did not belong on the national list of carcinogens.
Sodium nitrite is a compound that is used to “cure” meats. Cured meats have a characteristic color, unique taste and a longer shelf life. Centuries ago, nitrate was used in the form of saltpeter to cure meats before refrigeration was available. This was especially important in preventing the growth of the bacteria Clostridium botulinum, which causes the very deadly disease botulism.
In the 20th century, meat processors shifted to the closely related sodium nitrite because it was more reliable in its effects. Since sodium nitrite has been commonly used in commercially prepared meats, no cases of botulism have been linked to these products in the U.S.
Cured meats contribute very little nitrite to the total diet – less than five percent. The major source of human nitrite exposure is vegetables, especially root vegetables like beets and leafy greens. These foods contain nitrate and when nitrate reacts with your saliva in the mouth, it becomes nitrite.
In the 1970s, a single study that was later discounted cast a dark cloud over nitrite, alleging that its use in cured meats could cause cancer. In response, the U.S. National Toxicology Program (NTP) began a multi-year rat and mouse feeding study to determine if nitrite posed a health risk. In May 2000, a panel of experts reviewed NTP’s findings and concluded that nitrite was safe at the levels used and did not belong on the national list of carcinogens.
‘Alternatively Cured’ Meat Products
Despite nitrite’s safety, meat and poultry processors recognize that some consumers prefer meats that are cured using natural nitrate and nitrite sources like celery powder. These products are increasingly available in your grocery stores.
While meat processors believe these products should be called “cured” because they are cured by the presence of ingredients like celery powder, USDA regulates the label and requires that the products say “Uncured.” In a smaller font, the package declares “No nitrates or nitrites added except for that which naturally occurs in celery powder.” This labeling approach is required by USDA.

in a Hot Dog?
What You See on the Label Is
What You Will Find in the Product
Urban legends have led some consumers to wonder – what’s really in a hot dog? While there is much mystery and mystique surrounding hot dog making, the actual process is fairly simple. Small pieces of meat called trimmings, which result when large carcasses are cut into steaks and roasts, are ground in a large chopping bowl and blended with ice, salt, seasonings like garlic and paprika and sodium nitrite. The ingredients form a batter that is inserted into long strands of cellulose casings that are pinched at regular intervals. They are cooked thoroughly, showered in cool water and the casings are removed. The products are then packaged.
Some consumers think that variety meats like hearts or livers are included, but this is rarely the case. While variety meats are safe and wholesome, they are not commonly consumed by Americans and so they are not commonly added to hot dogs. If they are, the product must be called ‘Hot Dogs With Variety Meats” or “Hot Dogs With Meat Byproducts.” The ingredient statement must declare which variety meat was used. A look at the popular brands of hot dogs in the marketplace today will show that it is very unusual to find hot dogs with variety meats in the retail meat case.
Bottom line: what you see on the label is what you will find in the product.
Meat and poultry processors pride themselves in providing a range of products from classic products, reduced fat, reduced sodium to beef, pork and poultry options with different flavors.
Nutrition Benefits and Options
Research continues to document the benefits of protein in the diet, particularly in controlling hunger and in managing weight. 4 Processed meat and poultry products are convenient sources of protein that are packed with key vitamins and minerals including iron, B-vitamins, thiamin and zinc. In fact, meat and poultry products are among the most nutrient dense foods – meaning they offer high nutrition benefits per calorie. Meat and poultry processors understand that people have different health and wellness goals and needs and pride themselves in providing a range of products from classic products, reduced fat, reduced sodium to beef, pork and poultry options with different flavors. Today’s meat and poultry case offers choices for everyone.
Final Thoughts: Balanced Diet
The meat and poultry industry offers many processed meat and poultry choices that are convenient, tasty and nutritious and that meet a range of taste preferences and nutrition needs. Consumers should feel confident in including processed meat and poultry products – from a convenient, marinated pork loin, to a deli turkey sandwich to a juicy bratwurst – as part of their healthy, balanced diets.
