How to tell if onions (cut) has gone bad
Most vegetables fade in quality long before they become unsafe. Trust your senses before any calculator — including ours. Throw onions (cut) away if you notice:
- An off, sour, or unusual smell that wasn't there when fresh
- A slimy, sticky, or tacky surface texture
- Visible mould or unexpected discolouration
- It's been past the safe window in the table above
⚠️ Bacteria that cause food poisoning often produce no smell, taste, or visible change. Food can look perfectly fine and still make you sick — that's why the time limits matter even when everything seems okay.
Storage tips for onions (cut)
Use the crisper drawer and its humidity setting: high humidity for leafy greens, low for anything that rots when damp.
Revive limp vegetables in ice water for 15–30 minutes — limp is a hydration problem, not a safety problem.
