Swallowed Plum Pit: Risks, Cyanide Concerns & When to Seek Care

Accidentally swallowing a single plum pit (stone) is usually harmless—it typically passes uneventfully. However, risks exist:

Potential Hazards

• Sharp tip: Can scratch esophagus or, rarely, lodge in throat.
• Blockage: Multiple pits or fragments may cause intestinal obstruction, especially in children or those with strictures.
• Amygdalin → cyanide: Pits contain amygdalin, which releases hydrogen cyanide when crushed/chewed. Swallowing whole pits releases negligible amounts—the hard shell prevents significant exposure.
• Aspiration: Inhaling a pit into the airway (rare) is a medical emergency.

What to Do

Monitor for: difficulty swallowing, severe abdominal pain, vomiting, fever, or breathing trouble. Seek medical attention if any develop. For children or multiple pits, consult a clinician proactively.

Prevention

Spit out pits. Teach children to do the same. Consider pitted varieties for young kids.
