Food pests are organisms that invade food supplies, causing contamination and spoilage. Common examples include cockroaches, ants, and rodents, which can carry diseases and compromise food safety. These pests are often attracted to food sources due to improper storage or sanitation practices. Preventing food pests involves maintaining cleanliness in kitchens and food storage areas. Sealing food in airtight containers and regularly cleaning surfaces can help deter these pests. Additionally, monitoring for signs of infestation, such as droppings or gnaw marks, is essential for early detection and control.
