How to Tell If Sausage Is Bad
Quick answer
Sausage is bad if it smells sour, feels slimy, or looks gray or moldy. Raw sausage lasts 1–2 days in the fridge, and cooked or fully cooked smoked sausage lasts 3–4 days once opened.
When in doubt, throw it out. Bacteria that cause food poisoning often don't change the smell or look. Go by the time limits below too.
Signs Sausage has gone bad
- Sour or rancid smell. Sausage should smell of the spices and meat. A sharp sour, ammonia, or old-grease smell means it is past its prime.
- Slimy casing. A tacky, slick feel on the casing or on cut ends signals bacteria growth.
- Gray or green meat inside. Cut a sausage open and look. A gray, green, or faded interior is a bad sign, especially with an off smell.
- Mold on casing. Fuzzy spots on fresh or cooked sausage are a stop sign. Dry-cured types may carry harmless white surface bloom, but fresh sausage never should.
- Too many days in the fridge. Bacteria can multiply silently in ground meat. Raw sausage past 1–2 days is a risk even if it looks fine.
Looks weird, but it's fine
- Pale or reddish tint from spices. Paprika and other seasonings give sausages a wide range of colors.
- Wet-looking casing right out of the package. A little moisture from packaging is normal, as long as it is not sticky or smelly.
- Browning on cooked links. Slight color change from reheating or air exposure is normal if it smells fine and is within date.
How long does Sausage last?
| Where | How long | Note |
|---|---|---|
| Fridge (raw) | 1–2 days | |
| Fridge (fully cooked, opened) | 3–4 days | |
| Fridge (fully cooked, unopened) | Use by the package date, about 2 weeks | |
| Freezer | 1–2 months (raw), 1–2 months (cooked) | quality, not safety. Frozen at 0°F stays safe indefinitely |
| Counter | Max 2 hours (1 hour above 90°F) |
How to store it
- Keep raw sausage on the bottom shelf, away from ready-to-eat foods.
- Freeze raw links in a single layer first, then bag them, so you can pull out as many as you want.
- Cook raw pork or beef sausage to 160°F and poultry sausage to 165°F, then check with a thermometer.
Use it up before it turns
Frequently asked questions
How can you tell if sausage has gone bad?
Trust smell, feel, and color: a sour odor, slimy casing, gray interior, or mold means toss it. Also count the days, because safe-looking sausage can still be too old.
Can you eat sausage past the date on the package?
Unopened, fully cooked sausage kept cold may be fine briefly, but raw sausage should be cooked or frozen within 1–2 days of purchase. When in doubt, throw it out.
Does cooking kill bacteria in spoiled sausage?
Cooking kills live bacteria, but not the toxins from spoilage. If it smells or feels wrong, do not cook it.
