Thousands of types of bacteria are naturally present in our environment. Microorganisms that cause disease are called pathogens. When certain pathogens enter the food supply, they can cause foodborne illness. Not all bacteria cause disease in humans. For example, some bacteria are used beneficially in making cheese and yogurt.
Very close to everywhere on Earth.
yes it is true that some bacterias are not pathogens
Some are, some aren't. Parasites are pathogens and can be quite large in some cases.
Means that bloodborne pathogens may be present.
Sputum culture is the laboratory procedure for determining which pathogens are present.
Yes, pathogens are agents capable of causing infections or some types of diseases. Pathogens are normally on our skin and any objects without causing problems. Not all pathogens succeed in their goal to find a host, but many pathogens do.
chlorine dioxide does kill pathogens in the body and is extremely effective but it is not a naturally occurring element so I would question it but not disregard it if I was extremely sick in any way.
No sulfur dioxide is not present naturally. It pollutes the water.
This means that the food has been treated in some manner to kill pathogens that may be present in it. This can be done with heat, chemicals, radiation, or pressure.
Toxins
Pathogens such as E. Coli (coliform bacteria) can cause diarrhea. Other pathogens may cause intestinal infections, fever, nausea, vomiting and dehydration, among other things.
