Microbes need a food to survive
Microbes are decomposers. And they will begin the process of removing nutrients from food by breaking down the food.

Microbes are in our food but for a good reason. They are in our food to keep there blood pumping. Microbes are also used in our foods so then our sugar level keeps the same.
It depends on the amount of salt. It can "pull" the water out of the microbes, killing them. This is the reason salt is used to preserve food as microbes can't grow on very salty food.
Most of the time, after you eat the food, your stomach juices destroy them if there isn't too many too handle.
If you mean microbes, yes your food is full of them.
Microbes can be prevented from spreading through measures such as regular handwashing, disinfection of surfaces, and proper food handling practices. For example, handwashing with soap and water helps to remove microbes from the hands, while disinfecting surfaces kills microbes present on them. Proper food handling practices, such as cooking food to the appropriate temperature, help to kill microbes that may be present in the food.
Common microbes found in food include bacteria (such as Lactobacillus and Escherichia coli), yeasts (such as Saccharomyces cerevisiae), and molds (such as Aspergillus and Penicillium). These microbes can play a role in food fermentation, spoilage, and foodborne illnesses if present in high numbers.
