Which pest is commonly associated with food products?

The Indian meal moth is commonly associated with food products because it is primarily a pest of stored grains and processed food products. This moth is known for infesting cereals, flour, nuts, and dried fruits, making its presence a significant concern in food storage and processing facilities. The larvae of the Indian meal moth can feed on various food items, and they can contaminate these products with their webbing and droppings, leading to quality degradation and potential health risks for consumers.

In contrast, while the German cockroach, termite, and housefly do interact with food environments, their associations are not as directly tied to food products as the Indian meal moth. German cockroaches may inhabit kitchens and contaminate food, and houseflies can carry pathogens from waste to food. Termites, on the other hand, are wood-destroying insects that target structural wood rather than food items. Therefore, the distinct relationship of the Indian meal moth with a wide range of food products makes it the correct answer in this context.
