Canning botulism


There is a recent rise in home canning. With the wave of interest has been concern about the safety of home canning. Most people are turning to home canning in an attempt to make healthier choices for themselves and their families. Making them sick is counterproductive!

What is botulism?

A greater concern in home canning is botulism. Botulism is caused by a bacterium that is literally everywhere. This bacteria is not the problem, however. It is when the bacteria enters a perfect environment for development, which creates a toxin. The toxin is what is fatal.

This rare but often fatal food borne illness grows well in low-acid, liquid, air-free environments. Ideal place for botulism to grow a lot is a vase incorrectly in canned foods with low-acid (such as meat or vegetables).

A terrifying botulism is that it is not possible to get there (unless you are working in a lab environment and groping). Foods contaminated with it will not look or smell different.

Symptoms of botulism

After eating something that contain botulism usually takes 12-38 hours (but sometimes up to 10 days) for symptoms to appear. It is important to get medical aid AMeSWS. Botulism occurs only if some 20-25 cases per year, approximately 10% of them are fatal. Treating it early is a key to survival.

Some of the symptoms to watch for include: dry mouth, blurred vision, slurred speech, vomiting, diarrhea, difficulty swallowing and respiratory failure.
