When a home has been the site of a suicide, homicide, or fatal accident, it can become a biohazard. Contaminated blood, saliva, or body fluids that have been spilled over a long period of time can cause dangerous microorganisms and toxins to spread. Additionally, if a home is filled with dirt and debris, it can become a breeding ground for bacteria and other pathogens. Feces, urine, vomit, and other body fluids can carry these pathogens with them.
Rotten food can also attract insects and rodents that can spread contagious diseases. To protect the health and safety of the occupants of the house and their pets, it is essential to thoroughly clean and disinfect any home that has become a biohazard. This will help to prevent the spread of infectious diseases.
