I understand that bacteria makes the food rotten (side note is this in all cases?) but how does the bacteria get there in the first place? It cant just show up in rotten food. Is it a part of the plant/animal it came from or is it a result of food processing? If it comes from plants/animals then does the bacteria harm the plant/animal it originally came from when it was alive? Is it produced by the original animal/plant or is it something the animal picks up in the environment?
In: Biology
Bacteria are pretty much everywhere. In all organisms, in the soil, in the air, everywhere. Most of them are pretty harmless, but if you give them enough space to grow in the food, they can either produce toxins that make us sick, or they simply overwhelm out protective mechanisms and then infect our guts.
