Gross filth typically involves a building or residence that a reasonable person would find uninhabitable due to a combination of fecal matter, bodily fluids, excessive trash, expired food, odor, boxed items, mold, mildew, etc. The task of cleaning an area of gross filth can be challenging and often impossible for an individual untrained in decontamination and odor removal. In addition, those tasked with such a job must be trained in locating and safely eliminating biohazards. Blood, mold, mildew, and fecal matter can contribute to serious illnesses if proper precautions are not taken while cleaning a gross filth site.
