Question

a) How do house flies carry disease-causing microbes (or pathogens)?

Answer 1

• House flies feed on garbage, animal excreta, and dead organic matter.
• When the housefly sits on garbage or animal excreta for feeding, the millions of disease-causing microorganisms present in the garbage stick to the body of the housefly.
• When this house fly sits on uncovered food, they may transfer the pathogens and food gets contaminated.
• When this contaminated food is consumed by a person, pathogens enter into his body and cause various diseases.
