Meat-based sausages generally contain ground or chopped meat, fat, salt, and seasonings. Some recipes include binders or other ingredients, and some use a casing. Plant-based sausages use a different mixture, so there isn’t one ingredient list that covers every product.
The ingredients also don’t tell you whether a sausage is ready to eat or can be stored in a cupboard. Check both the cooking directions and the storage directions on its label. A smoked or dried sausage may still need refrigeration, cooking, or both.
What Goes Into a Sausage?
Sausage making has a long history, and recipes vary across regions. The University of Georgia’s guide to sausage making traces the word to the Latin “salsus,” meaning salted. But making meat into a sausage does not automatically preserve it for room-temperature storage.
It helps to separate the meat and seasonings from optional ingredients and the casing. Sausage can be sold as loose meat or patties as well as links, so a casing is not always part of the product.
1. Ground Meat
Common meat choices include pork, beef, chicken, and turkey. Sausage recipes can use meat trimmings, and some varieties include ingredients such as liver. Those details depend on the product, so check the ingredient list if you want to know which meats it contains.
Salt, herbs, and spices season the meat mixture. The amount of fat and the other ingredients vary with the recipe. Some sausages also contain curing ingredients or other additives, but you shouldn’t assume that every sausage has the same formulation.
2. Fillers
Fillers are optional. Depending on the recipe, ingredients such as wheat flour or nonfat dry milk may be used as binders or extenders. These ingredients can help with texture or moisture retention, but their function depends on the formulation.
The ingredient list on a meat or poultry product lists ingredients in order by weight, from the greatest amount to the least. Read it rather than assuming that a sausage contains breadcrumbs, milk, or any other particular ingredient.

3. Casing
A casing holds the sausage mixture in a particular shape. Natural casings generally come from the intestines of animals such as pigs, cattle, or sheep. Manufactured casings include collagen, cellulose, and plastic, but they are not all used in the same way.
Some manufactured collagen casings are edible and are made from animal hides. Cellulose and plastic casings are generally not eaten. So “manufactured” does not mean “inedible.” Follow the package’s instructions about whether to remove the casing rather than deciding from its appearance.
5 Different Types of Sausages
These five descriptions overlap. A sausage can be both cooked and smoked, while “vegetarian” describes what it is made from. They are useful ways to describe a product, but they do not replace its cooking and storage instructions.
1. Fresh Sausages
Fresh meat sausages are uncooked and must be refrigerated or frozen. Don’t eat them raw. Follow the package’s cooking directions and use a food thermometer to check the internal temperature.
Under USDA guidance, uncooked sausage made from ground beef, pork, lamb, or veal should reach at least 160°F (71.1°C). Sausage that contains ground chicken or turkey should reach at least 165°F (73.9°C). These temperatures are for cooking raw meat sausage; they are not instructions for curing or drying it.
Keep raw sausage and its juices away from foods that are ready to eat. After handling it, wash your hands with soap and water, and clean the utensils, cutting boards, and work surfaces with hot, soapy water.
2. Smoked Sausages
Smoking can add a smoky flavor, but a smoked sausage may be uncooked or fully cooked. If its label says that it needs cooking before eating, follow those directions even if the sausage looks cooked. The word “smoked” is not a doneness check.
Storage is a separate check. If the package says to keep the sausage refrigerated, do so even when it is fully cooked. Store it at room temperature only when the product’s instructions allow that, and check whether the directions change after opening.
3. Dried Sausages
Dry sausages have moisture removed during controlled processing, and some are fermented. This can change their flavor and texture, but drying is not the same as cooking. USDA notes that E. coli can survive dry fermentation, so a dry appearance is not proof that a product is safe to eat.
Some commercial dry sausages are shelf stable, while others need refrigeration. Shelf stable also does not necessarily mean ready to eat: some shelf-stable sausages still require cooking. Check both parts of the label, including what to do after opening, rather than assuming that a dry sausage never spoils.
4. Cooked Sausages
Cooked sausages have already been cooked during manufacture, and they may also be smoked. Bologna and frankfurters are examples. A fully cooked product can still need refrigeration, so follow its storage directions as well as any preparation instructions.
5. Vegetarian Sausages
Vegetarian and vegan sausages use a different mixture from meat sausages. For example, some products use soy protein, while others use pea and rice proteins along with plant oils and other ingredients that affect their texture. The ingredient list and Nutrition Facts panel are the useful guides to the product you are buying.
Plant-based sausages also have their own handling requirements. Some are sold frozen, while others are refrigerated, and they may need cooking before serving. Follow the package’s instructions rather than applying one storage time or cooking method to every vegetarian sausage.
How Do Sausages Taste?
Sausages can taste quite different because recipes use different meats or plant ingredients, seasonings, and processing methods. A smoked sausage may have a smoky flavor, while a fermented dry sausage may have a tangy flavor. Texture also varies, so you shouldn’t assume that every smoked or dried sausage will be firmer or more flavorful than a fresh sausage that has been cooked.

How To Store Sausages?
Start with the package’s storage instructions, including whether it must be kept refrigerated or frozen and what changes after opening. The guidance below is based on U.S. USDA and FDA advice for meat sausages. Plant-based products should follow their own package directions.
Keep your refrigerator at 40°F (4°C) or below. USDA recommends using raw fresh sausage within 1–2 refrigerated days, whether the package is opened or unopened. Once you cook fresh sausage at home, use it within 3–4 refrigerated days. Follow a shorter limit if the package gives one.
Those leftover times are for sausage cooked at home. Commercially cooked sausage and shelf-stable dry sausage have different storage instructions, so check the actual product rather than extending the same time to them. A product that can be stored in a cupboard while unopened may need refrigeration after opening.
Refrigerate perishable sausage within two hours, or within one hour if the temperature is above 90°F (32°C). Discard it if it has been left out longer. You cannot use its smell or appearance to establish that it is safe, and cooking it later may not remove toxins that developed during unsafe storage.
A “best if used by” date is about quality, not a guarantee that the sausage is safe until that day. The USDA explanation of food dates does not replace the need for proper refrigeration or the short storage period for raw fresh sausage.
If you won’t use raw sausage within its refrigerated storage time, freeze it while it is still safe. FoodSafety.gov lists 1–2 months in the freezer for best quality. Food that stays continuously frozen at 0°F (−18°C) remains safe indefinitely, although quality declines. Freezing does not make previously mishandled food safe; thaw sausage in the refrigerator rather than on the counter.
