Diseases from mouse poop are a hidden danger in homes. Mice often travel through kitchens and storage rooms, leaving droppings that contaminate surfaces and food. Harmful germs like Salmonella may cause stomach illness, diarrhea, and vomiting. Some infections spread without direct contact, simply by inhaling contaminated dust. To prevent sickness, clean affected areas with disinfectant, wash hands thoroughly, and store food in sealed containers. Regular home inspection helps reduce the risk of infestation.
