Explain Microorganisms Associated With The Raw Foods?

Foods of animal and plant origin are in direct contact with air, soil and water and get contaminated with the microorganisms present in these environments. Contact with already contaminated surfaces also adds the microorganisms. Further, plants can also become contaminated with the animal manure used as fertilizers. Similarly, animals obtain microorganisms through consumption of contaminated food and by contact with insects, pests and other animals and their faeces.
