Can you get food poisoning from canned food?
Canned goods, especially home-canned produce, can harbor a bacterium that needs no oxygen to multiply and is not destroyed by cooking. This bacterium causes botulism, a rare but potentially fatal food poisoning.

Can you survive botulism?
Although botulism can cause severe and prolonged symptoms, most people recover completely from the illness. Early treatment reduces the risk of permanent disability and death. However, even with treatment botulism can be fatal. Without treatment, more than 50% of people with botulism would die.
Can you get botulism from a dented can?
Botulism, caused by the bacteria clostridium botulinum, occurs when a dent or damage to a can creates even a pinhole-size opening. The mixture of air and moisture from the food within the can spurs growth of the bacteria, and the food becomes contaminated. … Dented cans are the biggest culprit of botulism.
How fast does botulism kill?
Symptoms usually appear within 12 to 36 hours (within a minimum and maximum range of 4 hours to 8 days) after exposure. Incidence of botulism is low, but the mortality rate is high if prompt diagnosis and appropriate, immediate treatment (early administration of antitoxin and intensive respiratory care) are not given.
Why is botulism so rare?
Spores are not killed by boiling, but botulism is uncommon because special, rarely obtained conditions are necessary for botulinum toxin production from C. botulinum spores, including an anaerobic, low-salt, low-acid, low-sugar environment at ambient temperatures.

At what temperature does botulism grow?
Nonproteolytic types grow between 38 and 113 degrees F, with an optimum for growth and toxin production at about 86 degrees F. For these types, refrigeration above 38 degrees F may not be a complete safeguard against botulism.

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.
