Cooking and laundry starch are both made from vegetable products, most commonly:
Both are usually considered nonpoisonous (nontoxic), but some older laundry starches may contain:
- Magnesium salts
- Polishing agents
Starch is found in:
- Cooking starch
- Cosmetic products
- Laundry products (laundry starch)
Cooking starch and laundry starch are different substances. There are many brand names for both. Other products may also contain starch.
Swallowing cooking starch can cause a blockage in the intestines and stomach pain.
Swallowing laundry starch over a very long period of time can cause the symptoms below in different parts of the body:
BLADDER AND KIDNEYS
- Decreased urine output
- No urine output
EYES, EARS, NOSE, AND THROAT
- Yellow eyes (jaundice)
HEART AND BLOOD
STOMACH AND INTESTINES
- Coma (decreased level of consciousness and lack of responsiveness)
- Convulsions (seizures)
- Twitching of the arms, hands, legs, or feet
- Twitching of the facial muscles
If the starch is inhaled, it may cause wheezing, rapid breathing, shallow breathing, and chest pain.
If the starch contacts the eyes, it may cause redness, tearing, and burning.
Seek medical help right away. DO NOT make the person throw up unless poison control or a health care provider tells you to.
If the person swallowed the starch, give them water or milk right away, unless a provider tells you not to. DO NOT give anything to drink if the person has symptoms that make it hard to swallow. These include vomiting, convulsions, or a decreased level of alertness. If the starch is on the skin or in the eyes, flush with lots of water for at least 15 minutes.

What to Expect at the Emergency Room
Bring the starch with you to the hospital, if possible.
For cooking starch:
The person will probably not need to go to the emergency room, unless they cannot drink fluids or are in severe pain.
For laundry starch:
The provider will measure and monitor the person's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated.
The person may receive:
- Activated charcoal
- Blood and urine tests
- Breathing support, including a tube through the mouth into the lungs and a breathing machine (ventilator)
- Chest x-ray
- ECG (electrocardiogram, or heart tracing)
- Fluids through a vein (by IV)
- Medicine to treat symptoms
How well someone does depends on how much starch they swallowed and how quickly they receive treatment. The faster medical help is given, the better the chance for recovery. Cooking starch is generally not harmful, and recovery is likely. Poisoning from laundry starch is more serious.
