What is a potential consequence of house flies landing on food or surfaces?

House flies are known to be carriers of pathogens and can easily transfer harmful microorganisms when they land on food or surfaces. Their bodies can pick up bacteria and viruses from decaying matter, waste, and other contaminated environments. When they subsequently land on food, they can deposit these pathogens, which can lead to the contamination of the food. This contamination poses a significant risk of foodborne diseases, as consuming such contaminated food can result in illness. Therefore, understanding the role of house flies in the transmission of diseases highlights the importance of effective sanitation and vector control measures in both commercial and residential settings to protect public health.
