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.

Gassiness, indicated by tiny bubbles moving upward in the jar (or bubbles visible when you open the can) Food that looks mushy, moldy, or cloudy.
Why are home canned foods most often the source of botulism?
Why is it found in canned goods? The bacteria Clostridium botulinum releases the toxin that causes botulism as part of its natural anaerobic process, meaning it multiplies in an oxygen-free environment, like a sealed can, Schaffner said.
Can you have a mild case of botulism?
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.
What should you do if you suspect botulism?
Seek urgent medical care if you suspect that you have botulism. Early treatment increases your chances of survival and lessens your risk of complications. Seeking medical care promptly may also alert public health authorities. They may then be able to keep other people from eating contaminated food.
Is botulism reversible?
Botulinum antitoxin is available and may be used to prevent the worsening of symptoms, though it will not reverse existing nerve damage. In severe cases, mechanical respiration may be used to support patients suffering from respiratory failure. The nerve damage heals over time, generally over weeks to months.
Is it OK to eat from a dented can?
Is it safe to use food from dented cans? If a can containing food has a small dent, but is otherwise in good shape, the food should be safe to eat. A sharp dent on either the top or side seam can damage the seam and allow bacteria to enter the can. Discard any can with a deep dent on any seam.
Does botulism grow in the fridge?
The proteolytic C. botulinum bacteria will never grow in the refrigerator – they cannot grow at temperatures below 12° C source.
Does Salt prevent botulism?
A concentration of about 10% salt will effectively prevent germination of Botulism spores in your canned food. Instead of messing around with acidity and water activity, the best way for the home canner to control the growth of C. Botulinum in low-acid foods is through pressure canning.
Can botulism grow in alcohol?
How can pruno give me botulism? When people make pruno, they usually ferment fruit, sugar, water, and other common ingredients for several days in a sealed plastic bag. Making alcohol this way can cause botulism germs to make toxin (poison). The toxin is what makes you sick.
Is there an antidote for botulism?
On March 22, 2013, the FDA approved the first botulism antitoxin that can neutralize all 7 known botulinum nerve toxin serotypes. The heptavalent antitoxin is derived from horse plasma and is the only drug available for treating botulism in patients older than 1 year, including adults.
Can pickles cause botulism?
Molds growing in pickles can use the acid as food thereby raising the pH. A raised pH increases the chance that harmful organisms (such as the organism that causes botulism) can grow. The proportion of vinegar to water in this pickling brine is 1 to 4 and is too low to be safe.
