Overview
Botulism is a rare but serious illness caused by Clostridium botulinum bacteria. The bacteria may enter the body through wounds, or they may live in improperly canned or preserved food.
What are symptoms of Botulism?
Symptoms usually appear 8 - 36 hours after consuming contaminated food. There is NO fever with this infection. In adults, symptoms may include:
- Abdominal cramps
- Breathing difficulty that may lead to respiratory failure
- Difficulty swallowing and speaking
- Double vision
- Dry mouth
- Nausea
- Temporary lack of breathing
- Vomiting
- Weakness with paralysis (equal on both sides of the body)
Symptoms in infants may include:
- Constipation
- Weakness, loss of muscle tone
- Weak cry
- Poor feeding and weak sucking
- Respiratory distress
- Alertness, despite weakness
What causes Botulism?
Clostridium botulinum is found in soil and untreated water throughout the world. It produces spores that survive in improperly preserved or canned food, where they produce toxin. When eaten, even tiny amounts of this toxin can lead to severe poisoning. The foods most commonly contaminated are home-canned vegetables, cured pork and ham, smoked or raw fish, and honey or corn syrup. Botulism may also occur if the organism enters open wounds and produces toxin there. Infant botulism occurs when living bacteria or its spores are eaten and grow within the baby's gastrointestinal tract. The most common cause of infant botulism is eating honey or corn syrup. Clostridium botulinum also occurs normally in the stool of some infants. Approximately 110 cases of botulism occur in the U.S. per year. The majority are in infants.
Who is at highest risk?
Infants are especially vulnerable to botulism. If you utilize home canning methods you, too, may be at an increased risk for contracting botulism.
When to seek urgent medical care?
Botulism can be life-threatening if left untreated. Contact your doctor immediately if you suspect you or your baby have botulism.
Diagnosis
The doctor will perform a physical exam. There may be signs of:
- Absent or decreased deep tendon reflexes
- Absent or decreased gag reflex
- Eyelid drooping
- Loss of muscle function/feeling
- Paralyzed bowel
- Speech impairment
- Urine retention with inability to urinate
Blood tests can be done to identify the toxin. A stool culture may also be ordered. Lab tests can be done on the suspected food to confirm botulism.
Treatment options
- Botulinus antitoxin is given.
- Breathing trouble requires hospitalization. The health care team will establish a clear airway and provide supportive therapy. A tube may be inserted through the nose or mouth into the windpipe to provide an airway for oxygen. A breathing machine may be needed.
- Intravenous fluids can be given when the patient has swallowing difficulties. A feeding tube may be inserted in the nose.
Cases of botulism are reported to state health authorities or the U.S. Centers for Disease Control and Prevention by health care providers so that the contaminated food can be removed from stores. Antibiotics are often given, but have not been shown to always be beneficial.
Where to find medical care for Botulism?
Directions to Hospitals Treating Botulism
What to expect (Outlook/Prognosis)?
Prompt treatment significantly reduces the risk of death.
Possible Complications
- Aspiration pneumonia and infection
- Long-lasting weakness
- Nervous system problems for up to 1 year
- Respiratory distress
Prevention
NEVER give honey or corn syrup to infants younger than 1 year old -- not even just a little taste on a pacifier. Prevent infant botulism by exclusively breastfeeding, if possible. Always throw away bulging cans or foul-smelling preserved foods. Sterilizing home-canned foods by pressure cooking at 250 degrees Fahrenheit for 30 minutes may prevent botulism. Keep foil-wrapped baked potatoes hot or in the refrigerator, not out in room temperature.
