Question

While returning from the school, Boojho ate chaat from a street hawker. When he reached home, he felt ill and complained of stomach ache and fell ill. What could be the reason? 

Answer 1

The reason could be that the chaat was contaminated by pathogenic microorganisms. The unhygienic conditions present near the shop becomes the breeding place for microbes, flies, etc.

The pathogens can be transmitted to places by flies and other vectors, even the utensil used for serving could have been contaminated by the pathogenic microorganism. If such microbial contaminated food is consumed several disease like diarrhoea, dysentery, cholera, etc., may occur.
