Diagnosis. To diagnose botulism, your doctor will check you for signs of muscle weakness or paralysis, such as drooping eyelids and a weak voice. Your doctor will also ask about the foods you've eaten in the past few days, and ask if you may have been exposed to the bacteria through a wound. Symptoms Difficulty swallowing or speaking. Dry mouth. Facial weakness on both sides of the face. Blurred or double vision. Drooping eyelids. Trouble breathing. Nausea, vomiting and abdominal cramps. Paralysis. Doctors treat botulism with a drug called an antitoxin. The toxin attacks the body's nerves, and the antitoxin prevents it from causing any more harm. It does not heal the damage the toxin has already done. US researchers take a strip off botulism. A test strip that can detect botulism-causing toxins has been developed by US researchers. The test detects the toxin and not the bacteria and distinguishing between them is informative as some serotypes (such as A and B) are most commonly associated with the disease in humans. Normal thorough cooking (pasteurisation: 70°C 2min or equivalent) will kill Cl. botulinum bacteria but not its spores. To kill the spores of Cl. botulinum a sterilisation process equivalent to 121°C for 3 min is required.

Prognosis. The paralysis caused by botulism can persist for 2 to 8 weeks, during which supportive care and ventilation may be necessary to keep the person alive. Botulism is fatal in 5% to 10% of people who are affected. However, if left untreated, botulism is fatal in 40% to 50% of cases.

In foodborne botulism, symptoms generally begin 18 to 36 hours after eating a contaminated food. However, symptoms can begin as soon as 6 hours after or up to 10 days later. If you or someone you know has symptoms of botulism, see your doctor or go to the emergency room immediately.

Symptoms usually begin within one to two days after eating contaminated food. Early or mild symptoms, which may go away on their own, include: Abdominal pain, nausea, vomiting or diarrhea (not usually present in wound botulism)

Botulism is a very rare but life-threatening condition caused by toxins produced by Clostridium botulinum bacteria. These toxins are some of the most powerful known to science. They attack the nervous system (nerves, brain and spinal cord) and cause paralysis (muscle weakness).

https://www.cdc.gov/botulism/general.html

Botulism (“BOT-choo-liz-um”) is a rare but serious illness caused by a toxin that attacks the body's nerves and causes difficulty breathing, muscle paralysis, and even death. This toxin is made by Clostridium botulinum and sometimes Clostridium butyricum and Clostridium baratii bacteria.

The botulinum toxin has been found in a variety of foods, including low-acid preserved vegetables, such as green beans, spinach, mushrooms, and beets; fish, including canned tuna, fermented, salted and smoked fish; and meat products, such as ham and sausage.

The first vaccine used to protect against botulinum neurotoxin was a chemically detoxified extract from Clostridium botulinum. A Pentavalent botulinum toxoid (PBT) vaccine in service today is administered under an Investigational New Drug (IND) application held by the CDC.

The proportion of vinegar to water in this pickling brine is 1 to 4 and is too low to be safe. Making sure enough vinegar is added to the cucumbers is important to make safe pickles; Clostridium botulinum can grow in improperly canned, pickled foods with a pH higher than 4. 6.

You cannot see, smell, or taste botulinum toxin—but taking even a small taste of food containing this toxin can be deadly. Low-acid foods have a pH level greater than 4. 6, which means they are not acidic enough to prevent the growth of botulinum bacteria.

Botulinum neurotoxin is considered a potential bioweapon because there is no FDA-approved antidote. Researchers have identified a compound that strongly inhibits botulinum neurotoxin, the most toxic compound known.

Everyone is at risk for foodborne botulism, especially those who eat home-canned, low-acid foods. Drug users, especially those who use black-tar heroin, may be at risk of wound botulism. Infants younger than 12 months who are fed honey are at risk of infant 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 a toxin. When eaten, even tiny amounts of this toxin can lead to severe poisoning.

When your case is mild, you may need weeks or months for a full recovery. It may take months or years to completely get over a very serious case. If the illness isn't treated, botulism can be life-threatening. But people recover in about 90% to 95% of cases.

W hat happens when someone gets sick from botulism? In food-borne botulism, symptoms usually begin 18 to 36 hours after eating a contaminated food. However, symptoms can show up as early as six hours or as late as 10 days.
