How safe is home canning?
Home canning is an excellent way to store and preserve produce and other foods. But it can be risky—and even deadly—if it’s not done correctly. Many home canners are not aware that improperly canned food can cause botulism, a rare but extremely serious form of food poisoning that can lead to paralysis and even death.
Can you kill botulism by microwaving?
The germs that cause food poisoning are killed in the microwave by the heat that is produced, not by radiation. “While the botulinum spores can survive in boiling water, the botulinum toxin is heat-labile. Microwaves can be very effective in the reheating process if used correctly.
Why is garlic in oil dangerous?
Garlic in oil is very popular, but homemade garlic in oil can cause botulism if not handled correctly. Unrefrigerated garlic-in-oil mixes can foster the growth of clostridium botulinum bacteria, which produces poisons that do not affect the taste or smell of the oil.

Eating raw garlic on its own doesn’t pose a threat of botulism, since it’s exposed to air. Nor does heating garlic in oil, or mixing raw garlic and oil and using it right away. To preserve garlic, you can put it in vinegar, which has a high acid content that will inhibit the growth of botulism.
