Excreta typically is defined as containing which of the following?

Excreta are commonly understood to be human or animal waste that can be a significant concern for public health and environmental sanitation, particularly due to its potential for containing high levels of pathogens. The correct response indicates that excreta can contain approximately 2,000 million fecal coliforms per 100 to 200 grams.

Fecal coliforms are a group of bacteria found in the intestines of warm-blooded animals and are often used as an indicator of fecal contamination. Their presence signifies that other harmful pathogens may also be present, which can pose health risks if they contaminate food, water, or the environment.

This level of fecal coliform presence is a reflection of the potential health risks associated with the management and disposal of human and animal waste. Understanding this quantitative aspect is crucial for environmental health specialists who monitor water quality and contribute to sanitation efforts.

In comparison, while the other options discuss fecal coliforms and the presence of hazardous substances, they do not provide a typical or accepted measure for fecal coliform in excreta. As a result, they fail to align with standard definitions used within environmental health practices. Thus, B captures crucial information that highlights the public health impact of fecal contamination
