How Long Do Bean Sprouts Last?
Bean sprouts last 2–3 days in the fridge and should be kept at 40°F (4°C) or colder. Cooked sprouts keep 3–4 days. The FDA and CDC advise cooking sprouts thoroughly, especially for higher-risk groups.
Bean Sprouts — raw
shelf life- Cooked: 3–4 days in the fridge
Fridge at 40°F (4°C) or below · freezer at 0°F (−18°C). Freezer times are for best quality; frozen food stays safe longer.
Bean sprouts are germinated mung beans or soybeans, grown for several days in warm, humid conditions. Those are the same conditions in which Salmonella, E. coli and Listeria multiply, and contamination often starts inside the seed, where washing cannot reach. They are among the highest-risk items in the produce section and among the shortest-lived.
How to store bean sprouts
- Buy sprouts only from a refrigerated case, choose the freshest date, and make them one of the last things into your cart and the first into your fridge.
- Keep them in their ventilated bag or a container lined with paper towels in the coldest part of the fridge, and plan the meal that uses them within 2 days.
- Rinse sprouts under running water before use, but understand that rinsing does not remove bacteria that are inside the sprout.
- Cook them until steaming hot throughout. A quick stir-fry or a minute or two in boiling broth is enough to greatly reduce the risk while keeping some crunch.
How to tell if bean sprouts have gone bad
- A musty, sour or fishy smell; fresh bean sprouts smell clean and faintly nutty.
- A slimy or sticky feel, or cloudy liquid collecting in the bag.
- Stems turning brown, translucent or limp rather than white, opaque and crisp.
- Dark, mushy root tips and wilted or rotting yellow heads throughout the bag.
Bacteria that cause food poisoning usually do not change the look, smell or taste of food. Go by the time limits first, and the signs above second.
Bean Sprouts shelf life chart
| State | Fridge | Freezer | Pantry |
|---|---|---|---|
| Raw | 2–3 days | Not recommended | Not safe |
| Use by the package date if sooner. Freezing turns them limp and watery. | |||
| Cooked | 3–4 days | 2–3 months | Not safe |
| As part of a stir-fry, soup or noodle dish. | |||
Not safe = perishable: no more than 2 hours at room temperature (1 hour above 90°F / 32°C). Not recommended = possible, but quality suffers or it serves no purpose.
Frequently asked questions
Is it safe to eat raw bean sprouts?
Raw sprouts carry a real risk, and health agencies advise against them for some people. The FDA and CDC say children, older adults, pregnant women and anyone with a weakened immune system should not eat raw or lightly cooked sprouts of any kind. For everyone else, thorough cooking is the way to reduce the risk. Fresh-looking sprouts can still carry bacteria.
Why do bean sprouts go bad so fast?
Bean sprouts are living, fast-growing seedlings that are nearly all water and have no protective skin. They keep respiring in the bag, which generates moisture and heat, and they arrive carrying a high load of microbes from sprouting. Even kept cold, they turn brown and slimy within 2–3 days.
Does washing bean sprouts make them safe?
No. Rinsing removes surface dirt, but the bacteria linked to sprout outbreaks can be inside the seed and the sprout tissue itself, where water does not reach. Home-grown sprouts are not safer either, since the contamination usually comes from the seeds. Only thorough cooking reliably reduces the risk.
Can you freeze bean sprouts?
Freezing raw bean sprouts is not recommended, because they thaw into limp, watery strands with no crunch. If you have extra, the better choice is to cook them into a dish within 2 days. Cooked dishes containing sprouts can be frozen for 2–3 months, though the sprouts will be soft.
