What Diseases Can Sewage Backup Cause in a Home?

Sewage contains viruses, bacteria, and parasites that can make you very sick if ingested. Norovirus is a frequent culprit, leading to stomach cramps, vomiting, and severe diarrhea. Bacterial infections from E. Coli or Salmonella cause similar symptoms and can be particularly dangerous for young children or older adults. These organisms enter your body through accidental hand-to-mouth contact after touching contaminated surfaces or floodwater.

Direct ingestion is not the only risk. Simply preparing food on a countertop that had sewage splash on it can transfer pathogens. The germs are microscopic and easily spread. If you experience sudden gastrointestinal symptoms after a backup incident, it is wise to consult a doctor and mention the possible sewage exposure. Prompt, proper cleanup is essential to remove these health threats from your home.

As sewage water sits, it can aerosolize, meaning bacteria and mold spores become airborne. Inhaling these particles can irritate your lungs and sinuses. This is a particular concern during cleanup activities like pumping or agitation. The resulting respiratory issues might include coughing, wheezing, or a sore throat, especially for individuals with asthma or allergies. In any climate, a damp environment can accelerate microbial growth after a spill.

Mold growth is a secondary but significant respiratory hazard. Damp materials left after water extraction provide an ideal environment for mold to flourish within 24 to 48 hours. Exposure to mold spores can trigger allergic reactions, asthma attacks, and other respiratory distress. Proper drying and dehumidification are critical steps that local water damage pros use to prevent this long-term air quality issue in your home.

• Inhalation of aerosolized bacteria from disturbed sewage.
• Irritation of the eyes, nose, and throat from contaminated air.
• Allergic reactions triggered by mold spores growing on wet surfaces.
• Aggravation of pre-existing conditions like asthma or bronchitis.
• Potential for more serious lung infections in immunocompromised individuals.
• Importance of using proper respiratory protection during any cleanup work.

Your immediate priority is to avoid contact with the contaminated water and materials. Keep children and pets far away from the affected area. Do not attempt to clean significant sewage spills yourself, as proper safety gear and disinfectants are needed. Instead, contact local water damage pros who are equipped for sewage backup cleanup and sanitation. They follow strict protocols to remove hazards and disinfect the space thoroughly.

Document the damage for your insurance company by taking photos before cleanup begins. Policies vary, and your insurer decides what is covered. Until the area is professionally cleaned and declared safe, treat it as a biohazard zone. Wash your hands frequently with soap and clean water, and see a doctor promptly if you develop any symptoms like fever, diarrhea, or skin infections after potential exposure.
