Are Plastics Toxic?

The Bottom Line

Ingested plastic is not toxic. If you swallow a small piece, it should pass through your digestive system without causing harm. If you choke on the piece of plastic or it gets stuck in your throat or esophagus, you may experience difficulty breathing or chest pain. If the piece of plastic is sharp, it could cut somewhere along your digestive tract, which can cause bleeding.

What happens if you swallow a small piece of plastic?

If you swallow a small piece of plastic, you will probably not experience any symptoms. A small piece of plastic will usually harmlessly pass through your digestive tract. You may see the plastic appear in your stool within 2-3 days, although it can sometimes take longer. You may also experience breathing difficulties if you choke on a small piece of plastic and aspirate (accidentally inhale) it into your lungs. 

Is plastic toxic if ingested?

Plastic is not toxic if ingested. However, if you swallow a large piece, you can experience symptoms such as nausea, vomiting, and/or stomach pain. If it gets stuck in the throat or esophagus, more severe symptoms such as difficulty breathing or chest pain can occur. If the piece of plastic is sharp, it might cut your digestive tract, which can cause bleeding. If you are allergic to plastic, you may experience asthmatic symptoms such as difficulty breathing or wheezing, as well as other signs of allergy. 

Can plastic get stuck in your digestive system?

If you swallow a piece of plastic and it enters the stomach, it will probably be able to pass through your digestive system. A larger piece of plastic could get stuck in your esophagus and cause difficulty swallowing and chest pain.

This Really Happened

A 12-year-old boy was eating a hot dog with a plastic fork and his mother noticed that a prong was missing. The boy stated that he may have swallowed it. He felt fine, until his mother started worrying about it, at which point the boy said that his throat might be sore. His mother called Poison Control, who asked about symptoms. The mother mentioned the sore throat. The boy was having no trouble swallowing, drinking, or eating. Poison Control told the mother that a small piece of plastic was not a problem and since his sore throat seemed to be due to worry rather than injury, he could stay at home. The mother was told to call back if he developed any further symptoms.
