Doesn’t sound like anything I want to mess around with!

Did you know that Clostridium
Botulinum spores are on most fresh food
It is in the dirt, it is just about everywhere.
The spores are harmless on fresh foods. However, when certain conditions exist, these spores will germinate, multiply, begin dying, and then produce a deadly toxin.
It is this toxin that causes serious food poisoning known as botulism.
The conditions where the spores become dangerous are:
Sounds just like the conditions in canned foods! Both home canned or commercially canned.
Botulism spores at temperatures above 240 degrees Fahrenheit. This is only achievable in a pressure canner.
As a home canner, If you follow the recommended guidelines, and process your foods with the correct canning methods you should have no problems.
As an added
precaution it is suggested that you boil low acid foods for 10 minutes before serving.
This includes all vegetables and meats.
There is apparently some debate even among extension services about whether this is a necessary step. To read more about this click here....
After talking with my local extension service , I have decided that the extra step is not that much work and it gives me peace of mind and so I do it. I'd recommend the same for you. You'll have to decide.
Boil for 10 minutes, plus one minute per 1,000 feet above sea level. Home canned spinach and corn should be boiled for 20 minutes before eating.
This is especially important at higher altitudes and in the Western United States. According to my local extension service, soil in the area from the Rocky Mountains to the Pacific Ocean contains higher rates of Type A Chlostridium Botulinum.
