<p>Botulism is a rare but serious illness caused by&nbsp;<em>Clostridium botulinum</em>&nbsp;bacteria. The bacteria may enter the body through wounds, or by eating them from improperly canned or preserved food.</p>

<h2><a id="1" name="1">Causes</a></h2>

<p><em>Clostridium botulinum</em>&nbsp;is found in soil and untreated water throughout the world. It produces&nbsp;<a href="https://medlineplus.gov/ency/article/002307.htm">spores</a>&nbsp;that survive in improperly preserved or canned food, where they produce a toxin. When eaten, even tiny amounts of this toxin can lead to severe poisoning. Foods that can be contaminated are home-canned vegetables, cured pork and ham, smoked or raw fish, and honey or corn syrup, baked potatoes cooked in foil, carrot juice, and chopped garlic in oil.</p>

<p><a href="https://medlineplus.gov/ency/article/001384.htm">Infant botulism</a>&nbsp;occurs when a baby eats spores and the bacteria grow in the baby&#39;s gastrointestinal tract. The most common cause of infant botulism is eating honey or corn syrup, or using pacifiers that have been coated with contaminated honey.</p>

<p><em>Clostridium botulinum</em>&nbsp;can be found normally in the stool of some infants. Infants develop botulism when the bacteria grow in their gut.</p>

<p>Botulism may also occur if the bacteria enter open wounds and produce toxins there.</p>

<p>About 110 cases of botulism occur in the United States each year. Most of the cases are in infants.</p>

<h2><a id="2" name="2">Symptoms</a></h2>

<p>Symptoms often appear 8 to 36 hours after you eat food contaminated with the toxin. There is NO fever with this infection.</p>

<p>In adults, symptoms may include:</p>

<ul>
	<li>Abdominal cramps</li>
	<li><a href="https://medlineplus.gov/ency/article/003075.htm">Breathing difficulty</a>&nbsp;that may lead to respiratory failure</li>
	<li>Difficulty swallowing and speaking</li>
	<li><a href="https://medlineplus.gov/ency/article/003029.htm">Double vision</a></li>
	<li>Nausea</li>
	<li>Vomiting</li>
	<li>Weakness with paralysis (equal on both sides of the body)</li>
</ul>

<p>Symptoms in infants may include:</p>

<ul>
	<li>Constipation</li>
	<li>Drooling</li>
	<li>Poor feeding and weak sucking</li>
	<li>Respiratory distress</li>
	<li>Weak cry</li>
	<li>Weakness, loss of muscle tone</li>
</ul>

<h2><a id="3" name="3">Exams and Tests</a></h2>

<p>The health care provider will perform a physical exam. There may be signs of:</p>

<ul>
	<li>Absent or decreased deep tendon reflexes</li>
	<li>Absent or decreased gag reflex</li>
	<li><a href="https://medlineplus.gov/ency/article/003035.htm">Eyelid drooping</a></li>
	<li>Loss of muscle function, starting at the top of the body and moving down</li>
	<li>Paralyzed bowel</li>
	<li>Speech impairment</li>
	<li>Urine retention with inability to urinate</li>
	<li>Blurred vision</li>
	<li>No fever</li>
</ul>

<p>Blood tests can be done to identify the toxin. A&nbsp;<a href="https://medlineplus.gov/ency/article/003758.htm">stool culture</a>&nbsp;may also be ordered. Lab tests can be done on the suspected food to confirm botulism.</p>

<h2><a id="4" name="4">Treatment</a></h2>

<p>You will need medicine to fight the toxin produced by the bacteria. The medicine is called botulinus antitoxin.</p>

<p>You will have to stay in the hospital if you have breathing trouble. A tube may be inserted through the nose or mouth into the windpipe to provide an airway for oxygen. You may need a breathing machine.</p>

<p>People who have trouble swallowing may be given fluids through a vein (by IV). A feeding tube may be inserted.</p>

<p>Providers must tell state health authorities or the U.S. Centers for Disease Control and Prevention about people with botulism, so that the contaminated food can be removed from stores.</p>

<p>Some people are given antibiotics, but they may not always help.</p>

<h2><a id="5" name="5">Outlook (Prognosis)</a></h2>

<p>Prompt treatment significantly reduces the risk of death.</p>

<h2><a id="6" name="6">Possible Complications</a></h2>

<p>Health problems that may result from botulism include:</p>

<ul>
	<li><a href="https://medlineplus.gov/ency/article/000121.htm">Aspiration pneumonia</a>&nbsp;and infection</li>
	<li>Long-lasting weakness</li>
	<li>Nervous system problems for up to 1 year</li>
	<li>Respiratory distress</li>
</ul>

<h2><a id="7" name="7">When to Contact a Medical Professional</a></h2>

<p>Go to the emergency room or call the local emergency number (such as 911) if you suspect botulism.</p>

<h2><a id="8" name="8">Prevention</a></h2>

<p>NEVER give honey or corn syrup to infants younger than 1 year old -- not even just a little taste on a pacifier.</p>

<p>Prevent infant botulism by breastfeeding only, if possible.</p>

<p>Always throw away bulging cans or foul-smelling preserved foods. Sterilizing home-canned foods by pressure cooking them at 250&deg;F (121&deg;C) for 30 minutes may reduce the risk for botulism. Visit the Centers for Disease Control and Prevention website for more information on home canning safety (<a href="http://www.cdc.gov/features/homecanning" target="_blank">www.cdc.gov/features/homecanning</a>).</p>

<p>Keep foil-wrapped baked potatoes hot or in the refrigerator, not at room temperature. Oils with garlic or other herbs should also be refrigerated as should carrot juice. Make sure to set the refrigerator temperature at 50&deg;F (10&deg;C) or lower.</p>
