Botulism

What is botulism?

Botulism is a severe type of food poisoning. It occurs when you eat food that contains a poison produced by a type of bacteria called Clostridium botulinum.

Botulism can be a fatal disease. The poison made by the bacteria can damage important nerves of the body and cause paralysis. If botulism is not treated right away, you may not be able to breathe and could die.

How does it occur?

Botulism occurs when the poison produced by Clostridium botulinum bacteria is eaten. It may happen when you eat food that has not been canned or preserved properly.

Botulism can also happen in wounds, but this is rare. It happens when the bacteria grow in a wound and make the poison.

Babies less than 1 year old can get botulism from honey. About 10% of all honey contains the bacteria. The bacteria can grow well in baby’s gut. The bacteria and their poison can make the baby very sick.

What are the symptoms?

Symptoms usually start 18 to 36 hours after you eat contaminated food. In some cases it may be several days. The symptoms include:

• trouble with your vision, especially double vision and trouble focusing
• drooping eyelids
• trouble swallowing
• trouble speaking
• weak muscles
• trouble breathing.

Fever is not a symptom of botulism.

If you suspect that you have eaten food contaminated with botulism, call your healthcare provider right away or go to the emergency room. If botulism is not treated right away, botulism can kill you.

How is it diagnosed?

Your healthcare provider will ask about your symptoms and about food you have eaten recently. Your provider will examine you and take samples of your blood and the suspected food, if it is available. The samples will be tested in the lab for poison produced by Clostridium botulinum bacteria.

How is it treated?

You may need to stay at the hospital. In all cases, this illness requires close observation. Because the nerves to the breathing muscles may be affected, it is important to keep close watch of your breathing. If your breathing muscles stop working, a ventilator (breathing machine) will be used. The machine will let you to keep breathing until the poison is out of your body. This can take days to weeks.

Your healthcare provider may give you antitoxin medicine to counteract the poison.

How long will the effects last?

The symptoms of botulism may last several days. If botulism is not treated, you may not be able to breathe and can die.

How can I take care of myself?

Follow all of your healthcare provider's instructions, including when you are to check back with your provider.
