In the ER, Sarah was able to describe her symptoms to a physician. The physician made note of what Sarah had eaten during the last 24 hours and was especially interested in the fact that Sarah s grandmother canned all of her own vegetables. The physician observed that Sarah s breathing was becoming labored. She ordered Sarah s blood sampled, her gastrointestinal tract pumped, and a mechanical respirator prepared for use. Fearing that Sarah suffered from a case of botulism, she asked that Sarah s grandparents be contacted and samples of the Thanksgiving meal retained, if possible, and sent to a local clinic for analysis.
Botulism is a form of food poisoning caused by exposure to a toxin called botulin.
Botulin is produced by Clostridium botulinum, a spore forming, anaerobic bacterium that can contaminate food. Whereas commercially canned foods are specifically heated to destroy botulinum spores, home canned foods that are not boiled for a half-hour prior to canning may be contaminated. The botulin toxin binds to the presynaptic membranes at motor end plates and prevents the release of acetylcholine from motor neurons, thereby preventing synaptic transmission and muscle contraction. The mortality rate for botulism is about 15 percent and the cause of death is suffocation. Enter your answer here.
