Spores in the form of spores live in the soil, along with vegetables and fruits fall into closed cans. Also vectors are mushrooms, grains, meat and fish.
Bacteria of botulism begin to multiply actively and release toxins in a medium without oxygen. Bacteria are extremely stable. Spores can withstand temperatures of up to 100 degrees, even for several hours. It is bent at a temperature of 120 degrees, with boiling for about half an hour. But such a high temperature is difficult to achieve at home. And these bacteria can withstand even a high concentration of acetic acid and salt.
