Botulism
A disease caused by the bacterium Clostridium botulinum, botulism is most often associated with food poisoning.
The bacteria,
which die in the presence of oxygen, thrive in closed bottles and cans. The
bacterium's characteristics make purification of foods difficult because it forms
spores which are resistant to high temperatures such as those generated
by boiling. When the spores reach a favorable environment, they become bacteria.
Botulism can also occur if the bacteria infects an open wound.
Symptoms of botulism are indirectly related to the bacteria; the real culprit
is botulinum toxin, a waste product that the bacteria produce. Botulinum toxin,
which interferes with the central nervous system, is one of the most lethal
substances known. Because of its effects, small amounts of the toxin, called
Botox injections, have been used to relax
muscles. The toxin, in aerosol form, has also been named a potential
biological weapon.
Symptoms
Botulism symptoms can appear up to three days after exposure to the bacteria
or its toxin. Sometimes, symptoms will appear in less than eight hours. These may include:
- problems speaking
- vision difficulties
- difficulty swallowing
- upset stomach and/or abdominal cramps
- difficulty breathing or temporarily suspended breathing
If you suspect you have symptoms of botulism, see a doctor immediately.
Treatment
An antitoxin can be used to treat the disease if symptoms are caught
early. Treatment usually includes hospitalization to assist with
respiratory difficulties. Botulism survivors may experience nerve problems up to
one year after the disease has been treated.
Reduce Your Risk
Battle food-borne botulism by throwing out misshapen cans, jars with
misshapen lids or broken seals (if never used), and preserves or canned foods
that look or smell less than fresh. Do not taste food items that
you suspect are spoiledonly a small amount of toxin can lead to the disease.
Infants and small children are at an increased risk because their intestinal
tracts cannot process the bacteria. As a result, it can grow unchecked, leading
to disease. For this reason, do not give a child raw honey or corn syrup, both
of which can contain the bacteria.
Be particularly cautious if you can preserves or other foods at home.
The only way to kill botulinum spores is to use a pressure cooker, and heat
foods to at least 250F for 30 minutes before canning.
