Pest Organisms / Oriental Cockroach
Risks
The main health concern is allergen exposure. Both the Illinois Department of Public Health and UC IPM tie cockroaches to allergic and asthmatic reactions; Illinois explains that shed exoskeleton fragments and feces act as airborne antigens, and UC IPM names indoor infestations a risk factor for childhood asthma.

They are also a food-safety hazard. Illinois DPH notes cockroaches transfer disease-causing bacteria — including those behind food poisoning — by contaminating food, preparation surfaces, dishes, and utensils, and Utah State independently lists disease transmission among the Oriental cockroach's potential risks.
