Which of the following is an example of a common pest?

Flies are considered a common pest in food service and handling environments because they can easily access food areas and carry pathogens that can contaminate food. Their presence indicates potential sanitation issues and poses a threat to food safety, as they are attracted to a wide range of food products and can quickly reproduce. Fly infestations can lead to serious health risks, making it crucial for food handlers to implement effective pest control measures to manage and prevent these pests.

While bees, ants, and butterflies may be prevalent in certain environments, they do not typically pose the same level of threat to food safety as flies do. Ants can also be a concern in some situations, but they are often less directly associated with the types of contamination risks that flies present in food handling contexts. Understanding the impact of common pests like flies helps food handlers maintain safe food environments.
