Bacteria are naturally everywhere, but with a stronger presence indoors due to their ability to rapidly colonize. Exposure to some indoor specific bacteria, either through the air or through a surface, is linked to infectious and non-infectious negative health outcomes.   Some of the common bacteria found indoors that cause health risks are: Staphylococcus aureus (S. aureus), Staphylococcus pneumonia (Pneumonia), Escherichia coli (E. coli), and Salmonella.

Sources of Bacteria:

Most bacteria are found on surfaces and/or on mediums such as food, water, hands, surfaces, and in the air (i.e. on particulates). The main sources that produce bacteria are humans, animals, soils, plants, and food.

Harmful Effects:

Bacteria can cause significant harm, especially to those who are immune compromised. Yet, still the heavy presence of bacteria can cause/spread infectious diseases, hypersensitivity pneumonitis, tuberculosis, legionnaires’ disease, food poisoning, and other illnesses.
