Name a common household pest associated with food contamination.

Cockroaches are highly regarded as common household pests known for their association with food contamination. They thrive in environments where food is present, often invading kitchens and pantries. Cockroaches can carry various pathogens that may lead to foodborne illnesses, as they tend to scavenge waste and decaying organic matter. Their droppings, saliva, and shed skin can contaminate surfaces and food, posing health risks to humans.

In contrast, while ants may also invade food sources, they are often considered more of a nuisance than a direct threat concerning foodborne illness. Spiders, generally beneficial for controlling insect populations, do not typically contaminate food. Termites primarily consume wood and cellulose materials, not food items, and do not pose a risk of food contamination. Therefore, cockroaches stand out as a primary concern in the context of household pests impacting food safety.
